摘要:
有源电力滤波器( active power filter,APF) 是一种动态抑制谐波和无功的电力电子装置,以并联型有源电力滤波器为研究对象,从 APF 补偿电流的控制和直流侧电容电压角度出发,分析了电源电流控制方式,实现补偿电流的检测及双闭环反馈控制,提高系统的补偿精确度和动态响应性能。另外,直流侧电压的指令值都是根据电网电压的工作范围、APF 的直流侧电容、额定输出电流、PWM 逆变器输出侧电感、电流电压调节器以及调制策略等参数设计的,在考虑直流侧电压与 APF功率损耗和补偿性能关系的基础上,提出了采用下垂调节器设计逆变器直流侧电压的控制参考值,使其兼顾 APF 的功率损耗及补偿性能综合平衡的优点。仿真结果验证了该 APF 控制系统的正确性和有效性。
Abstract:
he active power filter( APF) is a dynamic power electronic device to suppress the harmonicsand reactive power. From the perspective of the compensation current and DC side capacitor voltage ofAPF,a three-phase,three-wire parallel type active power filter applied detecting source current controlmethod to achieve the compensation current detection and the double closed loop of current control,whichimproved the compensation accuracy and dynamic performance. Moreover,DC link voltage reference wasdesigned according to operating space of the grid voltage,DC link capacitor value,rating output current,output inductance value,current regulator,voltage regulator,and modulation strategy etc. Based on the re-lationship between DC link voltage and power loss and APF compensation,
the droop controller was adopt-ed to achieve a comprehensive optimization between active power loss and the compensation performanceof APF. Simulation results prove the validity and feasibility of the APF control approach.
