摘　　要：针对银川东换流站运行时无功消耗量大的情况,通过分析直流输电系统无功产生的原因,计算无功消耗的大小,研究了±660 kV直流输电系统无功控制的方法,并提出了交流滤波器的控制原则和投切策略。应用结果表明:控制原则和投切策略确保了换流站交流母线电压在合格范围。Aiming at reactive power consumption large when operation in Yinchuan Eastern Converter Station, analyzes the causes of reactive power produced in DC power transmission system, calculates the amounts of reactive power consumption, studies the method of reactive power control in ±660 kV DC power transmission system, and puts forward the control principle of AC filter and switching strategy. The application result shows that the control principle and switching strategy can guarantee AC bus voltage of converter station within the qualification.
