安全稳定的控制系统是保证电网安全稳定运行的重要防线,亟须建立有效的现场测试方法,提高其可靠性。提出了一种仿真测试平台,采用4G/5G无线通信方式,远程控制各个厂站的测试终端,实现基于离线仿真数据的同步闭环测试,将安全稳定控制装置动作出口信号和报文与控制策略关联,实现故障仿真过程与装置动作结果的可视化展示和自动检验,辅助验证现场运行装置的控制策略的动态性能。该仿真测试平台既保证测试方案与电网运行方式高度一致,避免测试人员技术经验不足引发的电网安全风险,又有效减少了现场测试人员的工作强度。以新疆某地区电网安全稳定控制系统为实例开展试点应用,实现了稳控策略的远程仿真测试。

It has great significance to build an effective field test method and improve the reliability of the control system because a security and stability control system is a vital line of defense to ensure the operation of the power grid.This paper proposed a platform for simulation tests.It employed 4G/5G wireless communication to remotely control the test terminals of each plant station and realize the synchronous closed-loop test based on offline simulation data.In addition,it associated the action exit signal and message of the security and stability control device with the control strategy to realize the visual display and automatic inspection of the fault simulation process and the device action result.The visual display and automatic inspection could assist in verifying the dynamic performance of the control strategy of the on-site operating device.The result shows that the platform could ensure the test plan is highly consistent with the grid operation mode,and it could help avoid the grid security risks caused by the lack of technical experience of testers.Besides,the system could effectively reduce the work intensity of the field testers.An experimental application has been carried out with the power grid security and stability control system in a certain area of Xinjiang.Experimental results showed that the security and stability control system realize the remote simulation test.
