QF binary input closed Choose remote control & switching command PT switching On Choose local & BK binary input closed ≥ & PT switching terminals closed Section I PT assistant position input closed Section II PT assistant position input closed & Figure 2-1 Remote/local switching logical diagram 6 User’s manual of MPTS-820Hc PT paralleling and voltage protection Device WLD[K]-JY-309-2018 PT Manual Parallel/Dissolve： PT Switch function ON，put “PT switch ON/OFF” to ON ，-220V is tied to Terminal B01，+220V is tied to Terminal B03， circuit breaker QF in the closing position, B04 and B05 in any one terminal also access +220 V，There is a set of PT in the closing position, the other group in the opening position。+220V is tied to Terminal B02。When switch operates A01-A02、A17-A18、A19-A20、A21-A22、 A23-A24、A25-A26、A27-A28、A29-A30、A31-A32 should be connected，Also light up the Parallel light。 PT remote Parallel/Dissolve： PT Switch function ON，put “PT switch ON/OFF” to ON ，-220V is tied to Terminal B01，+220V is tied to Terminal B03 and B06，B04 and B05 in any one terminal also access +220 V，There is a set of PT in the closing position, the other group in the opening position。When the device receives a remote parallel command， A01-A02、A17-A18、A19-A20、A21-A22、A23-A24、A25-A26、A27-A28、A29-A30、 A31-A32 should be connected，Also light up the Parallel light。 The PT parallel contacts are disconnected when the device receives a remote Dissolve command。 2.2 Over-voltage protection function The device can monitor the voltage of 2 bus sections. When the maximum of line voltage of a bus section is higher than the over-voltage setting value and the delay is reached, the over-voltage protection will operate. The over-voltage operations of the 2 bus sections operate on different outputs. Figure 2-2 Over-voltage protection logical diagram 2.3 Low-voltage protection function The device can monitor the voltage of 2 bus sections. If any voltage of the 2 bus sections is normal,When the minimum line voltage of a bus section is higher than the low reverting voltage and the maximum line voltage of that bus is lower than the low voltage setting value and higher than loss-of-voltage setting, and the delay is reached, the low voltage protection will operate. The low voltage operations of the 2 bus sections operate on different outputs. Figure 2-3 Low voltage protection logical diagram 7 User’s manual of MPTS-820Hc PT paralleling and voltage protection Device WLD[K]-JY-309-2018 2.4 Zero sequence voltage alarm function The device can monitor the zero sequence voltage of 2 bus sections. When single-phase grounding occurs in a bus section, as its zero sequence voltage is greater than the setting value and the delay is reached, a zero sequence alarm signal will be given. Figure 2-4 Zero sequence over-voltage protection logical diagram 2.5 PT failure alarm function The device can monitor PT failure of 2 bus sections. It has the following criterion for any period of busbar PT. When PT failure protection is putting on, negative sequence voltage U2>8V, and the delay 10s is reached, it will be considered PT failure. When PT failure protection is putting on, negative sequence voltage U2<8V, and the delay 3s is reached, it will be alarmed as PT failure. 2.6 Display In normal operation, the LCD screen displays the protection line voltages on primary side of 2 sections Uab1, Ubc1, Uca1,Uab2, Ubc2, Uca2, opening triangle voltage of 2 sections U01,U02,and the frequency of 2 sections F1, F2 and communication address alternatively in turn. The high brightness LED displays the maximum voltage of 2 sections (1b, 2b). 2.7 Network print Device supports network printing function, can print remote control information, soe information and the setting parameter list. The printer IP address must been set rightly on the device(the network segment of printer must be as same as that of device IP addresses), then connect a printer, put on "real-time report print ", it can print the current remote control information or soe information when device is connected to the background(including remote communication shift, protection action), and can print the current soe information when device is not connected to the background. In addition, when press the "ok" button in the "print report" or "print setting value" menu, it can print the all setting parameter or the all report information, including action value. 2.8 Virtual correspondent node remote test The function is used to complete the communication node remote test of the device, do not need to access the actual analog electric quantity or the input quantity. Specific operation as follows, connect to the background, In the remote test menu, operate the “virtual input test”, the “virtual measure test” and the “virtual SOE test” menu in the “remote test” menu, press the "OK" button after the modification of 8 User’s manual of MPTS-820Hc PT paralleling and voltage protection Device WLD[K]-JY-309-2018 various settings, then by observing the background pop-up warning window or the change of the corresponding value, to determine whether the device communication node is right. It is convenient for debugger to debug the device on-site. 2.9 GPS clock synchronization The GPS clock synchronization signal is input as rs485 differential voltage, the device is able to receive GPS clock second synchronization. If there is GPS signal, there will be flashing on the bottom of cycle menu. Otherwise won’t. The principle of GPS clock synchronization: The second pulse or minute pulse act with the monitoring system, the time base with second precision is sent by monitoring system, when the GPS second differential signal arrives, the time base is unified and the milliseconds are cleared. The device is able to receive GPS clock second synchronization or IRIG-B through RS485 differential voltage, and it can be done with monitoring system to accomplish GPS precise clock synchronization or Ethernet-based SNTP synchronization. 2.10 Overhaul status When the device put into overhaul plate, remote sign, remote measure can uploading background computer. But the device can’t remote control by background computer. The SOE event、Alarm event、Trip event, etc also can’t uploading background computer. 3.
