摘要
研究了机电暂态程序PSASP的换相失败仿真方法,分析了2012年8月8日上海的多条直流逆变站连续换相失败对送端华中电网的影响。该仿真方法可以在故障起因和受端网架结构未知的情况下,利用WAMS录波数据在送端换流母线设置冲击负荷,模拟直流功率的波动,再现逆变侧换相失败对整流侧的扰动。实例仿真的结果验证了该方案的有效性。
The commutation failure simulation technique in the electromechanical transient simulation software PSASP is analyzed in this paper,and the continual commutation failures in Shanghai on August 8,2012 is taken as a case to illustrate the impacts on the sending terminal of East China Grid.Since the cause of fault and the topology of the receiving terminal are unknown,the recorded data of WAMS in the sending terminal can be used to set the impact loads at rectifier stations in order to simulate the DC power fluctuation and reproduce the disturbance of inverter-side commutation failures on the rectifier side.The simulation results verify the validity of the proposed method.
