SEL-400 Series TiDL Quick-Start Guide

Transcription

1 Getting Started This guide describes features and capabilities of the SEL-400 series relay with Time-Domain Link (TiDL ) technology. The SEL-400 series relays, including the SEL-421, SEL-451, SEL-487B, and SEL-487E, have the capability to receive analog input from the, a remote data acquisition system. The Axion provides the remote analog data over an IEC EtherCAT TiDL network. This technology provides very low and deterministic latency over a point-to-point architecture. What follows are simplified instructions for turning on the unit, modifying settings, and achieving basic operation. Please refer to the product-specific SEL-400 Series and SEL-2240 Axion instruction manuals for detailed operating instructions and protection element setting details. Unpacking and Inspection Unpack the relay and inspect the device for any external damage that may have occurred during shipment. After verifying that the relay is undamaged, ensure that the box also contains the following accessories: Step 1. SEL-C5300 power cable SEL-C662 front-panel EIA-232 cable Attach the power cable to the lower right-hand corner of the unit as shown in Figure 1. Ensure a solid protective ground connection by using the supplied SEL-C5300 cable ring lug connection. Figure 1 Relay Rear Panel

2 2 Figure 2 Ground Screw Detailed View of the Relay Power Connections The relay operates from a Vdc or Vac 50/60 Hz power supply. Exact power supply capabilities are model-dependent and are printed on the nameplate sticker affixed to the relay rear panel. Step 2. Please ensure that the safety ground connection (green conductor with a ring lug) is solid and fastened tightly to the ground screw to the right of the GND symbol, shown in Figure 2. Step 3. Apply power and verify that the relay turns on (within 10 seconds). Figure 3 shows the relay front panel. Figure 3 Relay Front Panel You can use relay front-panel pushbuttons to display relay measurements. Press the ENT pushbutton, for example, to display various current and voltage measurements. Measurement screens update approximately five times per second. Using the Front-Panel Menu to Check Remote Data Acquisition Connections Use the front serial port or Telnet (using Ethernet 5C or 5D) to modify relay settings. All existing SEL-400 series relay settings should be unchanged from previous firmware versions. Use the relay front-panel pushbuttons according to the following steps: Step 1. Verify that the relay displays the default Rotating Display screen as shown in Figure 4.

Rotating Display Screen ROTATING DISPLAY Line Current (A) RMS IA = IB = IC = FREQ = Press for menu If the relay displays something other than the default Rotating Display screen, press the ESC pushbutton to cycle to that screen. Then press the ENT pushbutton. The relay should display the Main Menu screen with the following menus. Hz MAIN MENU METER EVENTS BREAKER MONITOR RELAY ELEMENTS LOCAL CONTROL SET/SHOW RELAY STATUS VIEW CONFIGURATION DISPLAY TEST RESET ACCESS LEVEL Step 3. Use the front-panel Up/Down Arrow pushbuttons to scroll to and highlight METER. Then press the ENT pushbutton. This opens the Meter Menu screen, which displays the following menus. METER MENU RMS METER FUNDAMENTAL METER ENERGY METER MAX/MIN Establishing Serial Communication With the Relay Front-panel setting control is impractical for all but the simplest setting modifications. Perform the following steps to establish communication with the relay through use of a serial port interface: Step 1. Locate or download a USB port-based ASCII terminal emulation program (Tera Term or similar programs can be downloaded for free from Step 2. Step 3. Use the supplied SEL-C662 USB to EIA-232 cable to connect the front-panel serial port to the computer. Open a terminal emulation program (e.g., Tera Term).

4 4 Step 4. Use the drop-down menu to select the applicable serial port (see Figure 5). Figure 5 Tera Term New Connection Window Step 5. Set the terminal emulation program, as Figure 6 illustrates, to 9600 bps, 8 bits, no parity, 1 stop bit, and no flow control. Figure 6 Terminal Emulation Settings Window Step 6. Click OK and then press <Enter> to activate the session. Your cursor should advance to a new line, indicating successful connection with the relay. Depending on your terminal emulation setup, your display may show special characters (hearts or smiley faces) that represent the carriage return linefeed (CR LF) sequence shown in the Figure 7. Figure 7 Terminal Emulation Carriage Return Linefeed

5 5 Step 7. Step 8. Step 9. Type ACC and press <Enter>. If prompted for a password, type OTTER. Type 2AC and press <Enter>. If prompted for a password, type TAIL. You should now be at the second access level, from which you have access rights necessary to show and modify relay settings. Type such commands as SHOW or HELP to view settings, and type such commands as SET or SET G (for Global settings) to modify settings. Settings are self-explanatory, but some familiarity with the SEL-400 series relay will be necessary. IMPORTANT: It is strongly advised that all relays be commissioned/ operated with the password security feature enabled (SEL default). NOTE: You cannot change, Alias, or DNP settings until a valid topology has been commissioned and the relay is enabled. Please note this relay has been shipped with default passwords. For better security, change default passwords to strong passwords. You can also access the relay through Ethernet by using the Telnet protocol (which is also available through Tera Term and similar terminal emulation programs). To activate this function, it is necessary to first set the relay IP address. Do this by using the EIA-232 terminal access. Access the relay IP address and other Ethernet port settings by typing SET P 5 ( 5 is the Ethernet port on this platform). TiDL SEL-400 Series Relays Axion Remote Modules The SEL-400 series relays that support TiDL will all have a 4U chassis. The SEL-421, SEL-451, SEL-487B, and SEL-487E relays will support I/O on the main board as well as one additional I/O board. The main board and additional I/O board will be mapped to the 100- and 200-level inputs and outputs. Additional I/O for the 300, 400, and 500 levels will be provided by the Axion remote modules. The protection functions remain unchanged from the standard SEL-400 series relays. Refer to the product-specific instruction manual for protection functions and settings. The SEL-2240 Axion is a fully integrated analog and digital input and output (I/O) control solution that is suitable for remote data acquisition. An Axion node consists of a 10-slot, 4-slot, or dual 4-slot chassis configurable to contain a power module and combinations of CT/PT, Digital Input (DI), or Digital Output (DO) modules.

6 6 Figure 8 Axion Chassis SEL-2243 Power Coupler Each chassis will require a power coupler module (SEL-2243). This module will be responsible for supplying power to the rest of the node, as well as transmitting the data to the relay through fiber-optic communications. Although the power coupler has two fiber-optic ports, only PORT 1 will be used initially for TiDL. NOTE: The SEL-2243 Power Coupler must be installed in Slot A in the Axion chassis. There should only be one SEL-2243 module per Axion chassis. Figure 9 SEL-2243 Power Coupler The SEL-2243 has sufficient power capacity to accommodate an entire Axion node. The terminal strip at the bottom of the unit (shown in Figure 9) is the connection point for incoming power. All Axion modules have a 55-position IEC C-style connector that provides a communications and power interface to the backplane. See the SEL-2240 Axion Instruction Manual for more information. SEL Digital Input Module The SEL Digital Input module (see Figure 10) consists of 24 optoisolated inputs that are not polarity dependent. These inputs can be configured to respond to ac or dc control signals. The TiDL system will map as many as 72 DI points to the relay in the 300, 400, and 500 I/O board levels, based on the modules that occur in the network. Only the first 12 of 24 inputs will be used in each module to help distribute the I/O around the network more efficiently. The inputs are mapped to the relay inputs based on the order in which the DI module occurs in the TiDL network. There can be multiple DI modules in an Axion node, and the order of the DI modules will proceed from left to right in the node to determine the mapping of the inputs.

7 7 The first DI module that exists in the system, for example, on PORT, will map to IN301 IN312, and if a second module is available on PORT, it will map to IN313 IN324. If a second module does not exist on PORT, IN313 IN324 will be mapped from the next module appearing in the TiDL system. Mapping order determination starts with PORT and ends with the last port, PORT 6H. First SEL DI module Second SEL DI module Third SEL DI module Fourth SEL DI module Fifth SEL DI module Sixth SEL DI module IN301 IN312 IN313 IN324 IN401 IN412 IN413 IN424 IN501 IN512 IN513 IN524 Figure 10 SEL Digital Input Module SEL Fast High-Current Digital Output Module The SEL consists of 10 fast, high-current output contacts. The outputs will use the first 8 of the10 outputs and will be mapped as follows: First SEL DO Module OUT301 OUT308 Second SEL DO Module Third SEL DO Module Fourth SEL DO Module Fifth SEL DO Module Sixth SEL DO Module OUT309 OUT316 OUT401 OUT408 OUT409 OUT416 OUT501 OUT508 OUT509 OUT516

8 8 Figure 11 SEL Fast High-Current Digital Output Module For both the DI and DO modules, use AWG ( mm 2 ) wire of sufficient current capacity to connect to the digital inputs and output terminals for your application. The order of mapping for DO modules is the same as that for DI modules. SEL AC Analog Input Module The SEL is a protection class ac analog input (CT/PT) module that can accept three voltage and three current inputs. The module samples at 24 khz and is 1 A or 5 A software-selectable. Depending on the supported fixed topology, multiple CT/PT input modules can be installed in each node. Some topologies only support one CT/PT module per node. See Topologies for more information on supported relay topologies and their connections. Figure 12 SEL AC Analog Input Module Topologies Each relay will have a set of fixed topologies. These topologies will map the voltages and currents internally in the relay to maintain existing settings and functionality. When the TiDL system is commissioned (see Commissioning), the firmware validates the connected Axion nodes and identifies if the installed CT/PT modules in the system match one of the supported topologies in each SEL-400 series relay. s listed as optional in the following topology diagrams do not require a CT/PT module to be connected to them. All other ports require a CT/PT module to be connected in order for the relay to verify the topology.

The first module maps to the I01 I03 currents and V01 V03 currents, the second maps to the I04 I06 currents, and the third maps to the I07 I09 currents. Similar mapping occurs in the second Axion. Figure 23 SEL-487B Topology #3 Commissioning The TiDL system uses a commissioning feature to identify that the connected remote Axion nodes meet the requirements of the supported topologies for the applied relay. These topologies are a balance between copper reduction and number of nodes. The nodes must be connected in one of the supported topologies so that the relay will map the voltages and currents accordingly. The 400-series relay will have a new interface on its back panel that replaces the original CT and PT input connections. These standard inputs are replaced with a remote module interface that supports eight fiber ports, labeled PORT PORT 6H (see Figure 24).

16 16 NOTE: The relay only restarts and resets all settings (other than CTNOM) to default the first time the command is issued and only on subsequent changes of the CTNOM setting (i.e., changing from 5 to 1 or 1 to 5). If subsequent commands are given where the CTNOM setting is not changing, the relay only momentarily disables, but does not restart or reset settings to default values. NOTE: In order to change topologies, the relay must be restarted (either through a power cycle or the STA C command). After the restart, press the COMMISSION pushbutton to force the relay to reevaluate the topology. NOTE: Because the previously mapped topology is retained through a relay restart, you can commission a topology at a test bench and then install the TiDL relay in the substation yard. The relay will enable when the commissioned topology is reconnected to the relay. LED Status In TiDL applications, the relay receives currents from a remote module. It is required to set the nominal current input of the relay to either 1 A or 5 A. Many settings and ranges of settings depend on the nominal current. Use the CFG CTNOM n (n = 1 or 5 for 1 A or 5 A secondary CTs, respectively) command to set the nominal current value. This command is only available in relays that support the TiDL technology. Note that after issuing this command, the relay settings will be forced to their default values and the relay will turn off and back on again to reinitialize the settings. The relay defaults to 5 A nominal, so only use this command if you are switching to a 1 A setting (see Section 14: ASCII Command Reference in the SEL-400 Series Relays Instruction Manual for more information). The SEL-487E has multiple combinations of 1 A and 5 A inputs (see Section 2: Installation in the SEL-487E-3, -4 Instruction Manual for more information). In addition to the CT nominal values, TiDL relays also require the nominal frequency to be set by issuing the CFG NFREQ command. At Access Level 2, enter CFG NFREQ 60 to set the relay to 60 Hz nominal, or enter CFG NFREQ 50 to set the relay to 50 Hz nominal. This command is only available in TiDL relays. The relay defaults to 60 Hz. This command should be issued after the CFG CTNOM command and before settings are sent to the relay. Once all the remote Axion nodes are connected to the relay, press the COMMISSION pushbutton on the Remote Module Interface. This process will verify that the connected ports and Axion nodes are installed according to one of the supported topologies. Once the process is complete, the topology will be stored in memory. At each additional startup of the relay, the firmware will validate that the connected modules match those of the stored configuration. It will recognize if any of the CT/PT modules within the node have changed. If the topology has been changed or needs to be changed (e.g., modules are added or replaced), the relay will be disabled upon restart and the system will need to be recommissioned by pressing the COMMISSION pushbutton. When the commissioning and validation of the topology is complete, the voltages and currents will be mapped according to the topology assignments (see Topologies). Secondary injection testing will take place at each Axion node. Test sources will be required to inject voltages and currents to the Axion node to verify correct installation and mapping. Monitoring of the voltages and currents will remain in the control house with the relay. As shown in Figure 24, the TiDL relay provides LED status indication regarding the network and configuration. Once the system is connected and the COMMISSION pushbutton is pressed, the LEDs will provide the status of the commissioning process. Table 1 shows the status of the rear-panel LEDs for each commissioning state.

See the product-specific instruction manual for a full description of this process. The TiDL interface board has its own firmware upgrade process. The firmware for the TiDL interface board is stored on an SD card. This procedure will upgrade the TiDL interface board as well as the connected Axion modules. To upgrade the firmware, perform the following steps. TiDL Firmware Upgrade Remove From Service Step 1. Remove the unit from service. Step 2. Turn the unit off. Step 3. Remove the front panel. Upgrade Step 1. Step 2. Step 3. Install the SD card. Turn the unit on. Wait for the upgrade to complete. The LEDs located next to the SD card slot will indicate the status of the upgrade as follows. During the upgrade of the TiDL interface board, the eight LEDs will toggle sequentially from left to right.

18 18 During the remote module upgrade, the eight LEDs correspond to each port; i.e., PORT is the left-most LED, and PORT 6H is the right-most. As each module is updated, its corresponding LED blinks at a rate of four times per second. Once the upgrade is complete, the left four LEDs will remain on without blinking. If the TiDL interface board failed to upgrade, the left four LEDs will blink at a rate of twice per second. If any of the remote modules failed to upgrade, the right four LEDs will blink at a rate of twice per second. The upgrade process will be completed in less than 10 minutes. Recommission Step 1. Step 2. Step 3. Step 4. Step 5. Turn the unit off. Remove the SD card (recommended, but not required). Replace the front panel. Turn the unit on. Perform the TiDL commissioning process and return the unit to service. SD Card Slot Figure 25 TiDL Interface Board Factory Assistance We appreciate your interest in SEL products and services.
