| 摘要: |
| 智能变电站进行二次安措操作时，如果操作不当，可能造成保护误动或误闭锁，或无法确保运行设备与检修设备之间的有效隔离，从而造成严重影响。针对二次安措操作错误的产生原因，提出一种信号仿真方法用于二次安措操作校核。选取与保护功能相关的虚端子和压板进行仿真建模，通过信号在仿真模型中不同的流通情况，可以将安措操作中保护动作情况、闭锁情况、受检修影响情况通过仿真直观地展现出来，以此判断安措操作的正确性。 |

| Abstract: |
| When the secondary equipment of intelligent substation is operated with safety measures, if the operation is improper, protection maloperation or false locking may be caused, or the effective isolation between the operating equipment and the maintenance equipment may not be ensured, thus causing serious impact. In view of the causes of the operation errors of the secondary safety measures, a signal simulation method is proposed to check the operation of the secondary safety measures. Virtual terminals and platens related to protection function are selected for simulation modeling, and different flow conditions of signals in the simulation model can directly show the protection action, blocking situation and the situation affected by maintenance in the operation of safety measures through simulation, so as to judge the correctness of the safety measure operation. |
