Through theoretic reckoning and simulating analyzing, several control strategies for shunt APF were compared and chose ip-iq arithmetic ofthe instantaneous reactive power theory control strategy as the right scheme to produce the instructing current. Based on it, some new control arithmetic was subjoined to suppress the resonance in system and balance the dc side capacitor voltage. Two topologies of main circuit were compared and chose the three-phase voltage-source converter with a split-capacitor as its main circuit structure. The numerical scales of the dc side capacitor and inductance of reactors were calculated. The high-pass filters were designed to eliminate effectively the highfrequency harmonics produced by APF.

Other conclusion include: the trip of transient protection must be locked when the power circuit breaker of transimission line operated,because the trip is incorrect at this time;the features of transient current and its energy is different between the fault and thunder over- voltage in transimission line,and them can be identified;the ratio of high frequency component of current in serise capaciters compensation line , SVC and HVDC system is far little than fault transient current, so all of them do not affect the working of trasient current protection.

研究了在串联补偿电容的输电线路上发生故障时，串联补偿电容的MOV非线性保护电路对暂态保护的影响。串补电容MOV保护电路的非线性电流高频分量含量很小。静止补偿器、高压直流输电系统换流器的非线性特性产生的谐波分量含量极少。仿真计算表明，在与暂态保护判据中高频分量对应的频率范围内，其电流对应的功率谱估计值大大低于线路故障时故障电流的功率谱估计值，因此它们都不会对暂态电流保护的正常工作产生影响。
