摘要 砚山串补是南方电网第一个采用分段结构的串补工程。为深入研究这个串补工程的功能及动态特性,搭建了基于RTDS的双端等值电源模型和一个闭环测试系统。闭环测试系统由实时数字仿真器、砚山串补控制保护装置、功率放大器以及实际的线路保护装置等组成。用测试系统详细地模拟了一个串补分段,对另一分段则采用RTDS模型库中的固定串补简化模型。该测试系统引入大功率功放,实现了对砚山串补的电容器不平衡电流保护功能考核。由于将实际线路保护装置接入串补的闭环测试系统,从而可以对砚山分段串补动态特性、串补与线路保护之间协调动作特性进行研究。 Yanshan series compensation project is the first one with 2-sections in China Southern Power Grid. To study the function performance and the dynamic performance of the project, a RTDS-based two terminal equivalent source model and a close loop testing system are set up. The testing system consists of RTDS simulator, Yanshan series compensation control and protect devices, the power amplifier and the real line protecion device, etc. One section of the series compensation is simulated thoroughly by the testing system while the other is simulated with the FSC model of the RTDS library. A large power amplifier is introduced to check the capacitor-unbalance-current protect function of the project. Since the real line protection device is introduced into the close loop testing system, it is available to study the dynamic performance of the Yanshan series compensation together with the cooperation performance between the series compensation and the real line protection device.
