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.
