        摘 要:安全穩定的控制系統是保證電網安全穩定運行的重要防線,亟須建立有效的現場測試方法,提高其可靠性。提出了一種仿真測試平臺,采用 4G/5G 無線通信方式,遠程控制各個廠站的測試終端,實現基于離線仿真數據的同步閉環測試,將安全穩定控制裝置動作出口信號和報文與控制策略關聯,實現故障仿真過程與裝置動作結果的可視化展示和自動檢驗,輔助驗證現場運行裝置的控制策略的動態性能。該仿真測試平臺既保證測試方案與電網運行方式高度一致,避免測試人員技術經驗不足引發的電網安全風險,又有效減少了現場測試人員的工作強度。以新疆某地區電網安全穩定控制系統為實例開展試點應用,實現了穩控策略的遠程仿真測試。

        Abstract: 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 onsite 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.
