6 Chapter 2 VAr-Min Overview Valquest Systems, Inc. offers the new state-of-the-art capacitor control: VAr-Min. This intelligent capacitor control model incorporates proven microcontroller technology, serial RS- 232 ports to communicate to a PC, and industry-standard meter base connectors encased in durable polycarbonate enclosures. The VAr-Min is compatible with a wide selection of Distribution Systems and Configurations allowing it to function in a diverse set of operating environments. These capabilities along with its feature rich and friendly operating environment make the VAr-Min a versatile and economical instrument used to Measure, Control and Record and Analyze various system characteristics and respond with the appropriate action or user selected action. By implementing efficient hardware design techniques combined with user-defined or wizard generated control algorithms, real-time monitoring, and capacitor-bank switching capabilities the efficient management of capacitor banks are possible. Each capacitor control samples analog current and voltage waveforms and converts each signal into a digital format. An embedded software algorithm operating in a real-time mode measures and/or calculates the voltage, current, watts, VARs, phase angle and power factor. An efficient capacitor switching algorithm, preprogrammed by the user, uses these calculations and as well as possible other variables (such as Time or Temperature) to control the on/off capacitor bank switching capabilities. With an optional personal computer or laptop having a Microsoft Windows 2000, XP, or later based operating system and the VAr-Min companion software, users can exchange data between the computer and the VAr-Min internal memory for configuration, setup or data recording and analysis. The companion software is written using Microsoft Visual Basic and features the same look and feel of other windows based visual menu driven environments. The companion software also provides the user with the ability to visually examine the signal characteristics using tables, charts and graphs presenting the information needed to understand and make recommendations for corrective action and improved system performance. The software furnished with each VAr-Min capacitor control system is easy to use yet powerful enough to provide detailed information in report or graphical formats. Recording parameters and Report generators can be configured for short-term or long-term data recording modes (up to 273 days). Multiple data files are also supported for long term historical data analysis. This data can be directed to your computer screen, printed to a printer, stored in ASCII or standard spreadsheet formats such as Microsoft Excel. Valquest Systems Inc. Page 6 12/2/2009

7 VAr-Min Variants The VAr-Min is supplied to clients in many unique wiring configurations. These configurations are based upon factors such as type of Current Sensor, Temperature Sensor, Wiring requirements, Mounting Style and/or related Equipment located at the Installation Site. Before installation or when replacing a unit verify that the wiring and configuration is correct prior to connecting unit for proper operation. Valquest Systems Inc. Page 7 12/2/2009

48 Voltage Constants Control Group This control group consists of 3 dropdown list boxes which allow the user to select the conversion constants used by the capacitor control to correctly convert the voltage and current inputs to their correct engineering values. This is necessary so that the control can correctly and accurately calculate kwatt, kvar, and Power Factor values. The Voltage Constants defined are the Primary Phase-Neutral, Secondary Metering voltage and the Line Frequency. The list box options for each of the Voltage Constants are as follows: Primary Phase-Neutral ( in Volts) Secondary Metering (in Volts) Line Frequency (in Hertz) Power Direction Control Group This control group consists of 3 radio buttons (only 1 can be selected at a given time) to allow the user to define how the capacitor control is to detect the direction of the power flow positive, normal or reverse. The Positive (Always) option treats the direction as positive no matter the direction of power flow. The Normal option tells the capacitor control to treat the power flow away from the substation as positive and the power going into the sub-station as the negative. The Reverse option tells the capacitor control to treat the power flow as a signed value. However power flow away from the sub-station is negative and power flow into the substation is positive. Current Sensing Control Group This control group consists of 2 radio buttons used to select the type of Current Sensing unit (CT or Line Post Sensor (LPS). Based upon the Current Sensor type selected the individual control group changes. Valquest Systems Inc. Page 48 12/2/2009

The phase Difference dropdown list box provides the user with a method to select the Phase Difference for installations where the Voltage or Potential Transformer (PT) and the Current Transformer (CT) is not on the same phase. In a 4 wire Y, the phase difference will be 0,120 or 240 degrees. A Delta circuit will have a number of 90 degrees when the current is on the opposite phase of the PT or +/- 30 degrees on an adjacent phase. Valquest Systems Inc. Page 49 12/2/2009

50 Line Post Sensor In the Case of a Line Post Sensor, the Line Post Current Sensor (LPCS) control group consists of 2 dropdown list boxes to select the type of Line Post Current Sensor and the Maximum Expected Line Current (MELC), 2 text boxes are used to set the Current Sensor Ratio and Phase Shift as well as a single checkbox to enable/disable Harmonic Compensation for the Sensor. This is illustrated below: The user must select one of the LPCS types from the following list. The selection should be the same type used at the installation site. The available types are as follows: Generic Lindsey CVMI Lindsey MultiCore Fischer-Pierce 1301 x1a Fischer-Pierce 1301 x7a If the LPCS selected is pre-defined (any except Generic) the information for the Current Sensor Ratio, Characteristic Phase Shit and Sensor Needs Harmonic Compensation will be automatically filled in and these entry options will be grayed out. If the Generic LPCS option is selected, the user will need to fill in each of the characteristic items in there respective locations based upon the specific sensor data. Valquest Systems Inc. Page 50 12/2/2009

51 The Current Sensor Ratio setting is used by the internal calculations to convert the current sensor input to amperes. The Characteristic Phase Shift setting is used to compensate for the internal phase shift that occurs in the LPCS. The Sensor needs Harmonic Compensation checkbox is used to compensate for the nonlinearity at frequencies above 60 Hz. If this is checked, a mathematical compensation for the errors caused by the harmonic content of the 60 Hz waveform is applied to the measured current value resulting in a true current reading. Switching Delta-V This control group consists of 2 textboxes used to display the open and close switching voltages, 2 Vertical slider controls are used to set or adjust the switching voltages (between 0 and 10 volts in 0.1 volt increments) and a checkbox to enable or inhibit the learn mode for predictive switching values. Close - Open - The Close switching value is the voltage rise that is expected when the capacitor bank is connected to the line. A good starting value is 2.0 volts for each of these switching modes. The Open switching value is the voltage drop that is expected when the capacitor bank is removed from the line. A good starting value is 2.0 volts for each of these switching modes. Learn Mode - The capacitor control has the capability to adapt itself to the actual voltage changes that occur for the specific line connection. If enabled, these voltages will be calculated and used as part of the control algorithm. Valquest Systems Inc. Page 51 12/2/2009

Switch Status The Switch Status control group consists of a single textbox used to show the current switch status and 2 command buttons for Opening and Closing the switch remotely (via the pc/laptop). When the unit is in the Auto or manual mode, the 2 command buttons are not usable since all operations must be made manually from the front panel or are being controlled by the algorithm selected for automatic mode. When the unit is in Remote mode, the Open and Close buttons are activated and the user may select either function to set the switch position. These buttons work in a Boolean fashion, so when one button is pressed the other button will not be active. Example, if the Switch Status is closed, then the Open button will be active. If the Switch Status is Open, then the Close button will be active. Control Status The Control Status group consists of 2 textboxes used to show the time period for any currently pending switch operations as well as the delay prior to any switch operation which is to occur. Operating Mode The Operating Mode control group consists of a single textbox used to show the Mode (Auto, Remote or Manual) and 2 command buttons for which allow the user to set the VAr-Min in the Auto or Remote position. To control the VAr-Min Automatically or Remotely, the user must place the Auto/Manual switch on the front panel to the Auto position. This will enable the either the Auto or Remote command button in the Operating Mode control group Valquest Systems Inc. Page 67 12/2/2009

68 depending on the current setting. If the Operating Mode is set to Auto, the Remote button will be active, if the Operating Mode is set to Remote, the Auto control button will be active.

73 Chapter 7 Algorithm Builder Algorithm Builder The Algorithm Builder was introduced in a previous chapter, but because of its significance and importance in the user getting the most out of the capacitor control it is necessary to devote an entire Chapter to the Algorithm Builder dialog windows and the programming theory. When viewing template algorithms and developing algorithms it is very important to understand how these statements work as explained below: The algorithm is basically 2 separate loops that describe the behavior (when open - what the switch is to do)and the second loop describes the behavior (when closed- what the switch is to do). Depending on the state of the switch, the loop is serviced 1 time per second. Example: If the switch is open, the Switch Open loop will be examined and checked against the criteria 1 time per second until a test is met and the switch is directed to close. After the switch is closed, the Switch Closed loop will be examined and checked against that criteria 1 time per second until a test is met to direct the switch to trip (open). This process repeats itself based upon the users individual operating criteria. Select the Algorithm Builder from the SetUp dropdown list. Clicking the selection opens the Algorithm Builder dialog window. The following screen image illustrates this dialog box with a sample algorithm for Control on Time with No Override : Valquest Systems Inc. Page 73 12/2/2009

74 The Algorithm Builder dialog consists of 4 primary control groups. The first control group consists of 3 command buttons; Edit, Insert and Delete. These command buttons are by default inactive and only become activated when any of the programming statements have been selected in the With Switches Open or With Switches Closed Control groups. With Switches Open/With Switches Closed These 2 control groups With Switches Open and With Switches Closed are identical in function with the exception that the 1 st refers to Switch Open programming statements and the 2 nd refers to the Switch Closed programming statements. These control groups each contain a variable number of textboxes which contain programming statements and an Add Step command button. Pressing the Add Step command button in each of the windows will open up the Open Step # and Closed Step # dialog windows as discussed below in the Edit command button paragraphs. The (Edit, Insert and Delete) command buttons are used to act upon the actual programming statements contained within the With Switches Open and With Switches Closed dialog windows. When any of the programming statements have been selected Valquest Systems Inc. Page 74 12/2/2009

75 by the user (click on the statement) the statement will turn red indicating to the user that the statement has been activated for modification. In the following example, notice programming statement 1 within the With Switches Open dialog has been activated (visible in red) and that the 3 control buttons are now active and may be used as required to alter or modify the currently selected line. Edit The Edit command button is used to change or modify the currently selected line of code within the With Switches Open or With Switches Closed dialog windows. When this command button is pressed either of 2 dialog windows will be opened as shown: Valquest Systems Inc. Page 75 12/2/2009

76 Step Dialog (With Switches Open) Step Dialog (With Switches Closed) In the above example dialog windows, the dialog names were Open/Closed Step #0. The Step number will change based upon which line you are inserting or editing. If you were inserting or editing the 6 th line in the With Switches Open you would see the dialog name as, Open Step #6. Open/Close Step # The Open/Close Step # dialog windows contain 5 control groups: Parameter, Is, Value, If True, If False. These control groups and associated parameters are used to define the programming statements that determine what parameter is to be tested and the resulting action of the test prior to switch operations. The dialog also contains 2 control buttons; Add and Exit. Parameter The Parameter control group contains a radio selection list containing the primary control methods the user may select as the method of controlling capacitor switching. This selected parameter must be acted upon or influenced to cause an open/close operation based upon the test condition. Valquest Systems Inc. Page 76 12/2/2009

77 Is The Is selection list defines the test condition which must be met for the selected parameter and will vary according to the type of Parameter that has been selected. This is the action or test that must be valid for the selected parameter prior to initiating an open or close operation. Value The Value textbox is used to enter the limit or range value. This field will vary according to the type of Parameter that has been selected along with the particular units for the value. If True & If False The If True & If False control group statements specify what specific switching action(s) are to be taken as a result of the parameter test. Note that there are 4 specific options with may be selected as defined below: Stay Open This selection will either cause the switch to stay open or it will cause the switch to open (based upon a trip condition). Close This selection will either cause the switch to stay close or it will cause the switch to close (based upon a close condition). Next Step This selection is used when the current parameter or result must be checked and validated against another test condition described on the next line in the algorithm prior to changing a switch position. Skip Step This selection is used when the user needs to skip over a step and check for a different condition. OK Valquest Systems Inc. Page 77 12/2/2009

78 The OK command button is used to complete the editing or insertion process. When pressed, the currently statement defined in the Open Step # dialog will be placed at the selected location within the With Switches Open or With Switches Closed dialog window. Exit The Exit command button will close the Open Step # dialog and return the operator back to the Algorithm Builder dialog. Insert The Insert command button is used to add additional programming statements to the algorithm at the point of selection. In the following example, the left dialog window displays the selected line before the insertion process and the right dialog window shows the results of the insertion process. The programming lines must be edited after insertion. Before Insertion (@ Line 1) After Insertion Delete The Delete command button is used to remove and eliminate the currently selected line of code from the algorithm. The last control group consists of 4 command buttons; Read, Send, Wizard and Exit. Valquest Systems Inc. Page 78 12/2/2009

79 Read The Read command button is used to retrieve the current Algorithm from the VAr-Min and display the retrieved values and settings within the dialog window within the With Switches Open/Closed dialog windows. The following dialog will be displayed when the algorithm has been successfully retrieved from the VAr-Min. Send The Send command button is used to transmit the current Algorithm displayed within the With Switches Open/Closed dialog windows to the VAr-Min. The following dialog will be displayed when the algorithm has been successfully sent to the VAr-Min.

83 Chapter 8 Historical Window (VM Chart) & Data The Historical Report (VM Chart) window provides a user friendly method of quickly displaying previously saved historical trend data and presents this data to the user in Strip Chart format. This visual format makes analysis quick and easy because everything shown is based on the time domain. VM Chart also allows the user to create tabular reports and build Microsoft Excel spreadsheets. The Historical Report (VM Chart) window is comprised of zones or areas which provide the user with a simple means of selecting, observing and interpreting the historical trend data. As many as six (6) parameters can be displayed simultaneously. Each parameter has its own strip with its name (kw, kvar, Switches, etc.) shown on the left just above each one. These are selected from the Setup control button. Each time you start VM Chart, it will remember how you had it configured and will re-configure itself the same way until you enter the Setup window and re-configure the settings. Below is a description of the window and the various areas that contain information followed by a functional description of the areas. Valquest Systems Inc. Page 83 12/2/2009

84 Location Selection List Box Parameter/Command Selection Buttons Chart/Data Presentation Area Status Bar Handle Control File Selection List Box (Location) The File Selection List Box (Location) allows the user to quickly and easily locate and select a Historical (repsubs.dat) file for viewing and analysis. This control operates as a drop down list box and expands as the number of historical files expands within the directory. When the user has located and selected the file under review, a single click will open the file information and display the information based upon the settings in the setup menu. Chart/Data Presentation Area The Chart area is used to present a line graph representing the measured or calculated signal level versus time period. Parameter/Command Selection Command Buttons The parameter selection command buttons provide the user with a simple and easy method to select individual parameters for review and analysis. These parameters are as follows: Valquest Systems Inc. Page 84 12/2/2009

86 VM Chart Setup Command Window The VM Chart Setup window is a powerful tool used to configure the VM Chart Graphics window. The user has the ability to set the strip charts to a default setting in a variety of configurations based upon what is most frequently used for convenience; but the user also has the flexibility to change these settings as conditions and data warrant. Once these configurations are established the user may save these to specific files so that they can be easily recalled depending on specific user requirements without having to re-generate each setup prior to displaying the actual trend data. Below is a sample screen of the Setup window. (Notice that most of the functions are not available until the edit command button has been activated.) Setup Window (Edit un-activated) Setup Window (Edit activated in both control groups for user editing) File Menu Commands The File menu selection contains 6 sub-menu user selectable commands. The options are as follows (in sub-menu order): Valquest Systems Inc. Page 86 12/2/2009

87 Open This menu selection allows the user to open a previously saved (*.fmt) format file. (User doesn t have to re-configure setup each time when using this powerful feature) It is recommended that you provide a standard directory path and use descriptive file names when using this feature to facilitate easy file recall. In the following example, the format file selected is located in the c:\program files\var-min\ folder and the previously saved format file is named VoltTemp.fmt. Save This menu selection will save any changes of the user s current setup configuration into the same filename.fmt file that is presently open and being used for recalling at a later time period. (This will overwrite the setup that existed prior to the changes) Valquest Systems Inc. Page 87 12/2/2009

88 Save As This menu selection will save the users current setup configuration into the filename.fmt file. This file can then be opened and used at a later time period without re-creating the setup configuration. Print This command sends the chart page to the default printer and initiates the standard print function based upon the Print Setup configuration. The chart will print in color if sent to color printer. Print Setup This command provides the user with the Microsoft Windows Print Setup window. This allows the user make printer selections, configuration settings, etc., prior to beginning the actual print function. Build Excel The Build Excel command allows the user to create a Microsoft Excel spreadsheet from the data displayed on the chart page. When selected, the user will be presented with the File dialog box prompting for a filename. Specify the appropriate path and filename and save the data.

When activated each chart has a specific set of Vertical Handles located along the left side of the chart. The bottom chart also contains a Horizontal Handle set which allows the user to control the time period for all of the currently displayed charts. The following screen illustration shows the handles along the vertical graph axis and the horizontal graph axis. Horizontal Handle Vertical Handles Valquest Systems Inc. Page 94 12/2/2009

95 Horizontal Handles With the handles activated, the user can see how the chart can be expanded to focus on a specific area. The following window will demonstrate a detailed look at the beginning of the measurement cycle. Note the location of the horizontal handles. Valquest Systems Inc. Page 95 12/2/2009

96 Vertical Handles With the handles activated, the user can see how each strip chart can be expanded to focus on a specific area. The following window demonstrates the use of vertical handles on the top strip chart (kw). Note the location of the vertical handles and the scale setting as compared to the other 2 strip charts(kvar and Current). Mouse Control Chart Features Some very powerful and important user features are the mouse control chart features. These features allow the user a great amount of control in data analysis simply by moving the mouse over the data contained in the strip chart. When you move the mouse around the screen, you will notice that a pointing hand will appear when it is on one of the strips. You can see what the numeric values of the strips are by left clicking when the hand points to the desired horizontal location. Refer to the following figure: Valquest Systems Inc. Page 96 12/2/2009

97 Each time you click, a vertical line (cyan color above) will be shown which spans all the strips with values just above each strip. Down in the lower left hand corner, the Strip Chart Status Bar will show the date and time at the vertical line. You can make the vertical line go away by right clicking on a strip. If you move the mouse in between the strips you will notice that it will become a sizing symbol. This allows you to change the size of the strips so that you can see the information better. The figure below illustrates this point by expanding the kw strip chart and shrinking the other 3 strip chart areas: Valquest Systems Inc. Page 97 12/2/2009

98 As many as six (6) parameters can be displayed simultaneously. Each parameter has its own strip with its name (Voltage, kw, Current,Switches, kvar, etc.) shown on the left just above each one. These are selected from the Setup Page. Each time you start VM Chart, it will remember how you had it configured and will re-configure itself the same way. Exit The Exit command provides a means for the user to close the Historical (VM Chart) window and return to the main Menu Bar. Valquest Systems Inc. Page 98 12/2/2009

99 Chapter 9 Capacitor Control Simulator The VAr-min companion software includes a Capacitor Control Simulator. The Simulator is primarily used to assist in developing, training and testing various scenarios in which the Capacitor control may be used without the need of an actual VAr-Min unit. The following screen image illustrates the Simulator dialog window. Note that the left side of the dialog screen is very similar to the actual VAr-min hardware in appearance. The VAr-min panel controls also function very similar to the actual VAr-Min as well, except they are controlled using a mouse over control hotspots. The right side contains three control groups for user configuration and interaction. VAr-Min Simulator Panel The Capacitor Control Simulator shown below has 8 software hot-spots which allow the user to perform the same functions that would be manually performed on an actual VAr-Min. These software hot-spots are highlighted within the Red blocks in the following illustration. Valquest Systems Inc. Page 99 12/2/2009

100 Software hot-spots The hot-spots are controlled by placing the mouse over the position shown and clicking the left or right mouse button. This activity will produce the same result as the mechanical action on the real VAr-Min. Auto Clicking the Auto hot-spot will place the VAr-Min simulator in the Auto Mode. Manual Clicking the Manual hot-spot will place the VAr-Min simulator in the Manual Mode. Close Clicking the Close hot-spot will cause the VAr-Min simulator to manually Close the capacitor switch.

(This control responds to the left mouse click by acting as though the user is manually turning the Modify knob in the counter-clockwise position and responds to the right mouse click by acting as though the user is manually turning the Modify knob in the clockwise position.) << Clicking this hot-spot will allow the user to cycle through the menu displays from the current menu position back to the first menu choice. (This functions as though the user were turning the Modify knob in the Counter-Clockwise direction.) >> Clicking this hot-spot will allow the user to cycle through the menu displays from the current menu position to the last menu choice. (This functions as though the user were turning the Modify knob in the Clockwise direction.) The display and LED indicators function like they do on the actual VAr-Min. Version The version dropdown list allows the user to select the most appropriate version of the capacitor simulator. Load Parameters The Load parameters are user controls (Slider Bars) which allow the user to vary and adjust the various list of parameters for testing. This allows the user to have an algorithm or program defined and by adjusting the parameter(s) switch testing can be performed. The Load Parameters are as follows: Reverse Volts Freq Amps Angle kw kvar Valquest Systems Inc. Page /2/2009

102 Source Parameters The Source parameters are textboxes which allow the user to view the current levels or amplitudes of the respective parameters. The Source Parameters change based upon the changing load conditions. These parameters are as follows: Volts Freq Amps Angle kw kvar Line Parameters The Line parameters are textboxes which allow the user to change or configure the respective Line parameters. These may be changed by clicking within the textbox and changing the setting to a new value. These parameters are as follows: Voltage L-N Max Amps Bank kvar Switching dv Temperature C/ F Status The status icon is used to represent the capacitor bank switch positions. There are 2 icons which are used to reflect the Open and Close switch positions. Refer to the following illustrations: Open Switch Position Close Switch Position Valquest Systems Inc. Page /2/2009

103 Clicking on these icons forces the switch to change position. Example: If the switch is in the Open position it will be changed to Closed. Valquest Systems Inc. Page /2/2009
