摘　　要：提出的链式静止同步补偿器(STATCOM)阀周期触发和熄灭试验方法对于装置的工程化具有重要意义,既检验了阀的基本性能,又可以发现工程设计中的缺陷。结合上海西郊变电站±50Mvar链式STATCOM科技示范工程,根据PACAD仿真结果分析了阀在吸收无功和发出无功2种工况下的电压、电流应力。在此基础上,提出了阀周期触发和熄灭试验的试验方法及其试验电路,详细分析了电路的基本工作原理,建立了相应的数学模型,并利用PSCAD仿真软件加以验证。最后给出了试验结果,验证了试验方法的正确性。The periodic firing and extinction test method of STATCOM valve employing chain circuits is very important in its application. Combined with the design of ＋50Mvar chain circuits topology STATCOM, the voltage and current stresses of valves during different states are studied based on simulation results. The circuits, method and mathematical model for periodic firing and extinction test are presented. Furthermore, the principle is also investigated elaborately and proved by simulation with PSCAD. Finally the test results are given, which verify the feasibility and correctness of the test method.
