23 1MRK UUS B Section 3 Overview Section 3 Overview About this chapter This chapter presents a general overview of the. 3.1 Operator overview The Local human-machine interface (LHMI) on the IED provides an ideal mechanism for the day to day operation and even advanced use of the IED. The keypad, LCD and LEDs on the front of the IED are what constitute the LHMI. Troubleshooting, apparatus control, monitoring, setting and configuring are all possible via this interface. Through the screens and menu elements available, as well as the keypad, the user is able to navigate throughout the menu structure and move from screen to screen. This document is, to a great extent, arranged in the same way as the IED software is structured and describes all aspects of operation via the LHMI. The operator can document disturbances so that their causes can be analyzed and evaluated for future reference. For example, the fault currents and voltages at the time of the fault can be documented. The operator can also retrieve data about protected objects, providing further information for fault analysis. This implies viewing the mean value of current, voltage, power and frequency or primary and secondary measured phasors. The operator can check the IED status at any time. In some cases the operator may need to change the way the IED operates. This might include changing the active setting group or a parameter value. This must always be done strictly according to applicable regulations because un-authorized changes may lead to severe damage of the protected object especially if a fault is not properly disconnected. 3.2 Identify the IED To identify the IED, open the diagnostics menu. The identity of the IED along with other data is found under: Main menu/diagnostics/ied status/product Identifiers When the Product identifiers submenu is opened, the user sees the following screen: 17

This can occur on both X61/62 then shown in row 2 and X81/82 then shown in row 4 (Stator & Rotor) simultaneously or on ether of them. Analog output saturation. This status is set when the analog signal, current and or voltage, to REG670 IED is too high and may thereby be incorrect due to saturation in amplifier stage. Saturation status will be shown in the status column (column 1) in row 3 or 5 depending on the saturation occurrence 1 2 Over voltage blocked status overrides displaying of this status 3 Injection switch and over voltage blocked overrides displaying of this status Not applicable Backlight is on for 30 seconds after pressing any button. Backlight activation by pressing any button does not cause any other action than turning on the backlight. 32

39 1MRK UUS B Section 5 Understand the injection unit local human-machine interface 5.5 How to set frequency and voltage and current gain factors Frequency, current and voltage gain for the stator and/or rotor can be set and stored from the injection unit HMI. If a value is out of range, the limit value is stored. The display shows the latest stored settings. The settings are stored in non-volatile memory, which means that they remain stored in case IED is powered off Setting system frequency Frequency can be set to either 50 or 60 Hz. 1. Use the Up and Down button to select frequency. 2. Store the new frequency by pressing the Enter button, or clear the last stored frequency by pressing the Clear button Setting stator and rotor injection frequency Frequency can be set as integer in range 50 to 250 Hz for a stator and 75 to 250 Hz for a rotor. 1. Use the keypad to navigate to stator or rotor frequency (row 2 or 4) 2. Press E to enter value change state 3. Use the Up and Down button to select frequency 4. Store the new frequency by pressing the E (Enter) button, or clear the chosen frequency by pressing the C (Clear) button Selecting rotor gain Default (gain factor 3) is the recommended level, where a defined effect of worst case single fault at exciter circuit is allowed. A higher gain factor (4) may cause saturation in case of single fault in exciter circuit. A lower gain factor may be needed if the degree of disturbance is high. Change from default value only if requested by ICT tool during calibration procedure. Select rotor gain factor according to the table below. 33

40 Section 5 Understand the injection unit local human-machine interface 1MRK UUS B Table 4: Rotor gain Gain factor Note 1 Extreme 2 Enhanced 3 Default 4 Reduced Selecting stator gain Stator gain factor for both voltage and current depends on the highest voltage that may occur at the injection point of VT or DT. That voltage depends on the VT/DT ratio and the stator rated primary voltage. Select gain factor in accordance with highest voltage that may occur at the injection point. See Technical reference manual for exact formulas depending on particular injection arrangement. Table 5: Stator gain VmaxEF [V] Default value up to 120 Note Resetting overvoltage Stator and rotor injection output is protected against voltages exceeding maximum operating range (10% of rated VT/DT) by a relay blocking the injection circuit. This blocking is controlled by measuring the stator and/or rotor voltage, and remains blocked until manually reset. The blocking remains in the non-volatile memory when the IED is powered off. Overvoltage blocking is indicated by a symbol shown in Table 3. Resetting procedure: 34

41 1MRK UUS B Section 5 Understand the injection unit local human-machine interface 1. Power off the REX Press and hold the C and Key-lock buttons. 3. Power on the REX060 and wait until the status indication Over-voltage (symbol) disappears from the display. 4. Release the C and Key-lock buttons. REX060 stator and rotor overvoltage protection of injection circuit Both rotor and stator have two levels of protection, injection circuit interruption controlled by the voltage sense input and a fuse for over-current protection. The voltage controlled interruption, overvoltage, will normally occur prior to interruption by fuse and the reset sequence is described above. A blown fuse requires module disassembling to replace the fuse (F 4 A 250 V for stator and F 160 ma 250 V for rotor). However, if this occurs it is recommended to identify the reason for the overcurrent and take necessary actions to reduce the current before restarting the unit. The problem must be outside the injection unit since this unit cannot provide enough energy to blow the fuse. REX062 input protection REX062 limits overvoltage by a varistor at the injection output to stator. Normally, REX060 will interrupt the injection circuit in case of excessive over-current in the injection chain. Fuse within REX062 is an additional protection in case of failure within REX062 during over-voltage condition. A blown REX062 fuse requires a module disassembling to replace the fuse (F 6.3 A 250 V). However, if this occurs it is recommended to identify the reason for the overcurrent and do needed actions to reduce the current. 35

45 1MRK UUS B Section 7 Read measured values Section 7 Read measured values About this chapter This chapter describes measurement categories and how to locate them using the HMI. Each measurement category has a section of its own that includes a general description of the type of quantity being measured and the path in the local HMI to the measurement. 7.1 Overview The measurement menu contains primarily analog measurement data. External signals can also be viewed as they are or as they appear in the Signal Matrix Tool (SMT). These signals are a virtual representation of the hard wired signals on the various inputs and outputs. SMT is only accessible via PCM600 and is intended to simplify the configuration of the IED. It allows hardware changes to be made without having to reconfigure the internal logic. Signals that can be used in SMT are indicated with the Suffix SMT. The functions available under measurements are outlined below. 1. Analog primary values are the quantities measured on the primary side of the current and voltage transformers (CTs and VTs). 2. Analog secondary values are the quantities measured on the secondary side of the current and voltage transformers. These are the quantities measured on the Transformer module (TRM) inputs. 3. Analog mean values are the quantities measured at the inputs of the milliampere module (MIM). 4. Under Monitoring a number of submenus are available. These include Service values, Current phasors, Voltage phasors, Current sequence components and Voltage sequence components. 5. Metering displays the pulse counter and energy calculation and demand handling functions. The measurements available for pulse counter show pulse counter status data. All measurement descriptions in this document reflect the maximum number of hardware units possible in any application. In reality the hardware in the IED will be chosen according to a particular application. For example, it is possible to equip a 1/1 x 19 case IED with 14 I/O modules. In reality fewer I/O modules may be installed. In 39

46 Section 7 Read measured values 1MRK UUS B the measurements menu the operator will only see data from the hardware and software installed. Measurement for voltage channels used for injection protection (i.e. connected to REX060) will not display correct values because injection frequency differs from the rated power system frequency. To monitor these values use service values under respective protection function. 7.2 View analog primary values Overview The analog primary values are analog quantities measured on the primary side of the TRM and reflect the actual current or voltage on the primary side of the VTs and CTs. The ratio is adjusted under settings and also depends on the rating of the TRM. 24 primary values and phase angles are displayed in this view. The analog primary values are values on the input (primary equipment side) of the merging unit (MU) when IEC LE process bus communication is used. These values are scaled according to a fixed "universal" scaling of 1 ma per LSB and 10 mv per LSB and transmitted to the IED via IEC LE protocol. Main menu/measurements/analog primary values Displays the quantities measured by the transformer module (TRM) or received via IEC LE process bus. For each channel used the amplitude of the voltage or current and its phase angle is shown. If the amplitude is to low for calculation, the angle will be indicated with "- - -". The status of the module is always shown and channels not in use are indicated with "- - ". Data from TRMs and LDCMs as well as Merging Units can be viewed. All currents and voltages are given in RMS values. 7.3 View analog secondary values Overview 40

47 1MRK UUS B Section 7 Read measured values Analog secondary values shows secondary CT currents and VT voltages. These are the actual current and voltage values at the TRM inputs. For analog values received from Merging Units, no analog secondary values are shown. Main menu/measurements/analog secondary values Displays up to 24 channels with secondary CT and VT data. RMS values are shown. 7.4 View analog mean values Overview Measurements from the Milliampere Input Module (MIM) are found in this part of the measurements menu. Data from either the hard wired ma module or Signal Matrix Tool ma modules are shown here ma input module MIM Main menu/measurements/analog mean values/ma modules/mim:x Displays input data from the milli-ampere module which has six inputs. Each input has a range of +/- 20 ma. The value displayed on the screen is however dependant on the settings for the Milli-ampere Module. In the menu for settings, the range and a transformation factor can be adjusted to suit the application. This means that an input 3 ma may be displayed as temperature of 45 degrees. The output values shown are without units Signal matrix for ma inputs SMMI Main menu/measurements/analog mean values/smt ma modules/instance:x Displays the input signals coming into the Milli-ampere Module. Each module has six physical inputs with an input tolerance of +/- 20mA. The value displayed depends on the settings applied to this board which may for example cause an input of 3mA to show a value 30. The SMT ma modules are the virtual representation of MIMs in Signal Matrix Tool. 41

These indicate how well balanced a system is. In an ideal balanced system the zero sequence current should be zero, the positive sequence current should be equal to the current of each phase with the same phase angle (relative to GPS) as the A phase signal and the negative sequence current should be zero Voltage sequence component VMSQI Main menu/measurements/monitoring/voltagesequencecomponents(msqi)/ VMSQI:x 42
