1 Application Note Application-oriented testing of line differential protection end to end in the field using the corresponding RelaySimTest template Author Jens Baumeister Date Feb. 10, 2015 Related OMICRON Product CMC, RelaySimTest, CMGPS 588 Application Area Line differential protection end to end testing Keywords RelaySimTest, system testing, line differential protection, end to end testing, GPS synchronization, PTP Version v1.1 Dokument-ID ANS_14003_ENU Abstract Due to the increasing complexity of our electrical power systems, the need for highly selective protection is increasingly being fulfilled by the use of line differential protection. To test such a protection system thoroughly, a distributed end to end test with synchronized injection can be utilized. This application note describes how this could be done in an easy and comfortable way using the OMICRON RelaySimTest software. RelaySimTest offers simulation based system testing methods. To perform a test a fault scenario is calculated based on the simulation of the power system network. The resulting voltages and currents for the different relay locations can be used to test the correct behavior of the differential protection system. For this reason RelaySimTest offers the possibility to control several distributed and time synchronized CMC test sets. OMICRON Page 1 of 22

5 2 Introduction 2.1 General requirements Before you get started with this application note, read the Getting Started manual [1] of RelaySimTest. Please make sure that you also have a good knowledge about the CMC test system. 2.2 What this application note describes The application note describes the end to end relay tests of the RelaySimTest predefined line differential protection template. Therefore it covers the following content of the test template. 1. Line differential protection (general information) 2. System under test 3. Test cases 4. Test sets configuration The application note does not describe single end tests, wiring checks and parameter tests. To test the protection thoroughly such tests are also recommended. 2.3 Line differential protection A line differential protection system compares the current flowing into the protected area with the current flowing out of the protected area. Under normal conditions there should be nearly no difference between this currents. A high differential current (Idiff) indicates a fault on the line. The protection system should switch off the line as fast as possible if a fault occurs. Figure 1: Protection principle: no fault on the line (left); fault on the line (right) Some effects like capacitive currents and measurement errors lead to a relatively small differential current even if there is no fault. To prevent unwanted tripping due to these influences the protection system has to be stabilized. For this reason many relays calculate a bias (or stabilization) current Ibias. Depending on this a relay operating characteristic defines which differential currents have to lead to a trip and which not. OMICRON 2015 Page 5 of 22
6 Figure 2: Example of a differential operating characteristic The protected area is defined by the current transformer at the beginning and the end of the line. That means a line differential protection system provides 100% selectivity for the line, but no back-up protection for any other object. Faults outside of the protected area should not provoke a trip of the differential protection system. Figure 3: Protection principle - fault outside the protected area Figure 4: Line differential protection system Due to the fact that the line ends are distanced from each other, there has to be one relay on each end of the line. For the comparison of the currents a communication between the ends is necessary. With this communication the measured current values are transmitted to the relay at the remote end. This is often realized by optical fiber. Two synchronized CMCs are necessary to test such a distributed system with two ends (see chapter 5.1 ). For more information about line differential protection see [2] OMICRON 2015 Page 6 of 22
7 3 System under Test 3.1 Application example Protected line The following figure shows the line with its line differential protection system that is used as example in the RelaySimTest template. A CB A 3-pole trip time = 50 ms close time = 100 ms Trip 110 V CT A 600 A / 1 A Line Data 50 Hz Solidly grounded system 110 kv 600 A 32,5 km R = Ω/km X = 0.4 Ω/km RN/R = 0.6 XN/X = 0.6 CL = µf/km CN = µf/km CT B 600 A / 1 A CB B same as CB A Trip 110 V B Relay A communication connection Relay B Figure 5: Application example - protected line (CT: current transformer, CB: circuit breaker) The help menu of RelaySimTest shows the definition of CL and CN. 3.2 Settings of the System under Test menu in RelaySimTest The parameter of the protected line, the protection concept and the substations with their bays and relays according to the example (see chapter 3.1 ) are in the System under Test menu. The number colors in Figure 6 correspond to the colors of Figure 5 to show where the different parameters are defined. Comments: 1. Protected line: The settings of this menu item use primary values. The menu item does not include the definition of line capacitances. They are defined in the Model editor of the Test cases menu (see chapter 4.1 ). 2. Protection concept: The protection system uses telecommunication. 100% of the line length is protected with a nominal trip time of 0 s to clear faults on the line. 3. Bay A and B: This menu contains the trip and close time of the circuit breaker (CB). With this information the binary outputs of the CMC could simulate the behavior of the CB. However the test template doesn t use this feature. Furthermore the Bay menu item contains the sub menu Instrument transformers that includes the CT direction setting (see Figure 7). 4. Relay A and B: This menu item contains the test voltage and current limits. Relay manuals specify a voltage and a current that does not cause damage to the relay. The limits of RelaySimTest should be adapted to the current and voltage limits of the relay manual. Nevertheless it is important to do breaks between the tests to ensure that the relays are not stressed too much! OMICRON 2015 Page 7 of 22

9 4 Test cases Figure 8 shows the Test cases menu. It contains the tests with their corresponding grid topology (1), test scenarios (2) and test steps (3). The next three chapter describe these menus referring to the test template of the application note. Figure 8: Test cases menu 4.1 Application example Grid topology The protected line of the application example is part of the grid that is shown in Figure 9. Figure 9: Grid topology OMICRON 2015 Page 9 of 22
10 4.2 Suitable test cases This chapter describes the test scenarios of the RelaySimTest template. They are realized in the corresponding Design test scenario menu (see Figure 8 number 2). Figure 10 gives an overview of the different test cases, while the chapters to describe them in detail. In all test cases the relay trip command of relay A and B is observed. Chapter 4.3 describes how the measurement and assessment is realized. Figure 10: Suitable test cases (1: charging and load current, 2 and 3: fault on busbar, 4: fault on the protected line, 5: fault on the line with small differential currents) To keep the template simple, it uses only the following fault types: > L1-N > L2-L3 > L1-L2-L3 All test cases with faults include these fault types. Depending on the relays under test, on the relay s parameter and on the grid where the protection system is used, it can be necessary to add more fault types. The initial state of a fault is inactive to get transients in the beginning. The fault of test case 5 is an exception, because high transient currents are not wanted for this test (see chapter ). Figure 11: Example for a fault with Initial state "Inactive" OMICRON 2015 Page 10 of 22
11 The nominal trip time of the differential protection is 0 s, therefore the simulation time after a fault or switching event is at least 0.5 s. Hence the protection system has enough time to show its reaction on the event. Sometimes the behavior of the protection system depends on the prefault condition. For example it might be different if there is a load current during the prefault state. However for this example this distinction is not considered. Some of the following test cases are used to test the protection system with particularly high currents (Test case 2 to 4) and one is used to test it with particularly small currents (Test case 5). This is realized by using certain fault conditions like a certain fault location, inception angle or fault resistance. For example the fault resistance RF is set to 0 Ω in test cases where the fault currents should be high. However the impedances of the infeeds are not changed. In a real grid these impedances vary due to the different grid topologies that are used. For this reason those test cases which should lead to high currents can be further improved by using the minimum infeed impedances of the real grid. On the other hand test cases which should lead to small currents can be improved by using the maximum infeed impedances. A Siemens 7SD610 relay system was used to test the RelaySimTest template that belongs to this application note. For more information about this relay see number [4] of the bibliography Test Case 1 - Charging and load current This test case should show that the differential protection does not trip, if the charging current of the line capacitances flows and if a load current flows through the protected area. > First, the line is switched off CBs on both sites are open. Figure 12: Test case 1 > Afterwards CB A is closed, while CB B remains open. Due to the line capacitances a charging current flows. The differential protection system measures this current as differential current, but it should not trip, because there is no fault on the line. > After 0.5 s CB B is closed too. > The phase angle of infeed 2 is varied in 5 test steps between -20 and +20, while the phase angle of infeed 1 stays at 0. A load current flows due to the different phase angles of infeed 1 and 2. This current flows through the protected line. There is no differential current (except the charging and magnetization current). Therefore the differential protection is not allowed to trip. OMICRON 2015 Page 11 of 22
12 4.2.2 Test Case 2 and 3 Single infeed, fault on busbar These test cases should show that the differential protection does not trip, if a fault occurs outside of the protected area. > In test case 2 a fault occurs on busbar A. > Only infeed 2 is modeled, it will feed the fault current that flows through the protected line. Figure 13: Test case 2 > In test case 3 a fault occurs on busbar B. > Only infeed 1 is modeled to feed the fault current. > The fault inception angle of both test cases is 0 to get high transients. The fault current flows through the protected line. It differs between test case 2 and 3 due to the different source impedances of infeed 1 and 2. There is no differential current (except the load current). Therefore the differential protection is not allowed to trip Test Case 4 Double Infeed, fault on line This test case should show that a fault on the protected line leads to a trip of the differential protection. The height of the fault current depends on the fault location. Hence the fault is placed on different Fault locations. > Fault locations: 0%, 50%, 100% of the protected line. > The fault inception angle is 0 to get high transients. Figure 14: Test case 4 A fault on the protected line leads to a differential current. Therefore the protection system has to trip Test Case 5 Single infeed, fault on line This test case represents a fault on the line that is characterized by a particularly small differential current. OMICRON 2015 Page 12 of 22
13 > Only infeed 2 is modeled to get a small differential current. > Infeed 2 is chosen, because it has a higher source impedance compared to infeed 1. > The fault is placed at the beginning of the line (fault location 0% of the protected line) to have a high impedance from the system feeding the fault to its location (infeed 2, 100% of the protected line). Figure 15: Test case 5 > A fault resistance of 5 Ohm is used to reduce the fault current. (Number [3] of the bibliography shows how to estimate an arc resistance for a 110 kv grid.) > The initial state of the fault is Active to suppress transients. The fault has to lead to a trip, because there is a fault inside of the protected area even if the fault current is small. 4.3 Measurement and assessment The Define measurements menu of the Test steps tab (see Figure 8 number 3) defines the start and stop event for the trip time measurements. > The start measuring event is the beginning of a fault, if the fault has to lead to a trip. > The start measuring event is the beginning of the simulation (0s) for tests where the relays are not allowed to trip. > In both cases the trip command is observed. Therefore the moment when the trip signal becomes active is the stop measuring event. > The trip time is measured for relay A and B. Figure 16: Measurement OMICRON 2015 Page 13 of 22
14 The Set assessment condition menu (next to the Define measurements menu) defines the assessment of the test steps. For test points where the relays have to trip the option Automatically obtain min/max time grading set in System under test is active to use the time assessment of the menu Protection concept (see Figure 6 number 2). For those test points where the relay are not allowed to trip the option No stop event occurs is the assessment condition. Figure 17: Automatically obtain min/max OMICRON 2015 Page 14 of 22
15 5 Test sets configuration 5.1 Test setup Due to the distribution of the protection system an end to end test of a line differential protection system with two ends requires two CMCs. RelaySimTest offers the possibility to control both CMCs with one main application via internet. For this reason two computers with internet access are necessary one at the local and one at the remote end. The local PC runs the RelaySimTest main application, the remote PC just a proxy application which takes care of network connection issues and announces the test device to the controlling software application at the other end. This proxy application is the OMICRON Test Set Remote Agent. How to configure RelaySimTest and the Test Set Remote Agent for such an application is described in the next chapter. Figure 18 illustrates the end to end test setup. To perform a test the main application of RelaySimTest on the local PC calculates a fault scenario based on the simulation of the power system network. It calculates the voltages and currents not only for its own end but also for the remote end. The results are used for the end to end test where the main application controls the local and the remote CMC. To perform an end to end test for a line differential protection system synchronized injection of test currents is necessary. The synchronization ensures that both test sets the local and the remote one start the test at the same time. This is very important since any inaccuracy can result in an unwanted differential current and thus in an unexpected relay behavior. For this reason RelaySimTest supports the use of CMGPS 588 an antenna-integrated GPS controlled time reference to synchronize the starting point of a CMC test process. Each end needs its own CMGPS 588 (see Figure 18). It delivers a time signal using PTP (Precision Time Protocol). For more information about PTP see [5]. Figure 18: Scheme of an end to end test OMICRON 2015 Page 15 of 22
16 5.2 The Test sets configuration in RelaySimTest and the Test Set Remote Agent This chapter expects that the test set up according to chapter 5.1 is already done: > The local PC is running RelaySimTest, the remote PC the Test Set Remote Agent. > Both have Internet access. > The wiring between the CMCs and the relays is already done. > The local and the remote CMC are already switched on and synchronized via CMGPS 588. > If the connections between the CMCs and the PCs are done by Ethernet, it has to be ensured that both CMCs are associated to the local PC. The Test sets configuration menu (local PC) defines the CMCs and their configuration used for the tests. At first the test template includes two general CMCs as shown in Figure 19. The label on the left site of the CMC icon shows that the first CMC belongs to substation A and the second one to substation B. Figure 19: Test sets configuration menu of RelaySimTest (local PC) After a click on the Choose test set button on the right site of the CMC icon, a new window opens and offers the CMC that is connected to the local PC. A click on the local CMC selects it. Figure 20: Local CMC is selected The Test Set Remote Agent on the remote PC has to open an Internet session before RelaySimTest can control the remote CMC. The upper part of the Test Set Remote Agent shows the remote CMC. If the correct CMC is not already selected, it has to be chosen by using the Change test set button. OMICRON 2015 Page 16 of 22
17 A click on Grant remote access announces the remote CMC on an Internet server. After a short time the Test Set Remote Agent displays a session ID for the Internet session. The software offers also the possibility to use a session password, but this is optional. Figure 21: Test set remote agent (remote PC) OMICRON 2015 Page 17 of 22
18 A click on Connect to remote test set in the Test sets configuration menu of RelaySimTest (local PC) opens a window to enter the session ID from the remote end (see Figure 22). Figure 22: Connect to remote test set (local PC) Afterwards RelaySimTest displays both CMCs the local and the remote one. Figure 23 illustrates this. The test sets are ready for time synchronized injection due to the use of CMGPS 588. The green clock icon next to the CMC icons indicate that. Figure 23: Local and remote CMC connected to RelaySimTest The Getting Started manual of RelaySimTest [1] describes how the wiring between the CMCs and the relays can be configured in the Test sets configuration menu. OMICRON 2015 Page 18 of 22
19 6 Performing the test Before a test is started it is strongly recommended to do a wiring check. The execute buttons start the tests. There are different execute buttons - Execute all and Execute selected. What they mean depends on the menu where they are: > If a test case is open a click on the Execute selected button executes only the selected test step. A click on the Execute all button runs all test steps of the test case sequentially (see Figure 25). > In contrast to this in the Test Manager menu the Execute selected button runs all selected test cases, while Execute all runs all test cases (see Figure 25). Figure 24: Execute selected and Execute all button for a certain test case. Especially after tests with high currents it is meaningful to interrupt the test sequence with the Stop button. This ensures breaks between the tests to avoid too much stress for the relays. OMICRON 2015 Page 19 of 22
