摘要
设计了一种新型的单相有源电力滤波器(APF),应用特定消谐技术,不需实时检测负载的无功电流和高次谐波电流,即可实现同时补偿负载无功及高次谐波电流的需求。给出了一种优化特定谐波消除PWM技术开关角的求解方法;设计了单相有源电力滤波器PI控制器。仿真结果表明该滤波器具有响应速度快,稳定性好,能有效地消除和抑制谐波,并能够对无功功率进行灵活地调节等特点。
The paper designs a new type of single-phase active power filter（APF）,By applying selective harmonic elimination technique ,the APF can compensate the reactive component and high harmonics of line current without detecting the reactive current and harmonic current of the load. A switch angle＇s solution method of optical SHEPWM is presented, PI controller of the APF is also designed. The simulation results show the APF has the advantages of fast resPonse time and good stability, effectively restraining and eliminating harmonics, and flexible regulation of reactive power.
