摘要
文中基于并联型有源电力滤波器APF传统滞环、定频滞环、定频滞环和空间矢量相结合三种控制策略为目标,通过设计APF电路模型、内部谐波检测电路及选择参数,对APF三种不同控制策略下补偿的电网电压、电流波形及开关频率进行仿真。从APF三种滞环控制策略的补偿效果、开关频率与直流侧电压利用率等方面进行分析比较,验证了APF定频滞环SVPWM控制策略的优越性。
This paper base shunt active power filter traditional hysteresis, fixed-frequency hysteresis, fLxed-frequency hysteresis and space vector control strategies for combining three kinds of goals by designing APF circuit model, the internal harmonic detection circuit and select the parameters, APF grid voltage compensation in three different control strategies, the current waveform and the switching frequency simulation. APF were analyzed and compared in terms of the three hysteresis control strategy compensation effect, the switching frequency and DC voltage utilization, verify the APF fixed frequency hysteresis SVPWM control strategy superiority.
