数字仿真在电网控制保护装置入网检测中的应用

为了研究电力系统全数字实时仿真装置(Advanced Digital Power System Simulator,ADPSS)在宁夏电网控制保护装置入网检测方面的应用效果,以2套典型线路保护为检测样例,搭建系统模型进行仿真后,通过外接物理接口与保护装置连接,从而检验其动作特性。测试结果显示2套线路保护在所有类型的模拟故障中均动作合格。结果表明:利用ADPSS进行的控制保护装置检测试验,仿真度高、实时性强,可为装置入网提供可靠的试验依据,为系统的安全稳定运行提供良好的技术保障。

Application on digital simulation of the control protection device inspection before entrance power grid

In order to study the application effect of Advanced Digital Power System Simula?tor(ADPSS) for inspection before entrance power grid of control protection device in Ningxia PowerGrid, takes two sets of typical line protection as inspection example, after built system model to makesimulation, through external physical interface connecting with protection device, verifies its opera?tion performance, the test shows that two sets of line protection action is qualified in all types of simula?tion faults. The result shows that using ADPSS make control protection device inspection test has highsimulation level, strong real-time, which can provide reliable test data for protection device inspectionbefore entrance power grid, as well as offer better technological guarantee for safe and steady operationof power system.
