摘 要:为了消除由电力电子装置产生的谐波,提出了一种基于有功能量平衡控制的单相有源滤波器的设计方法.该方法不需要应用传统的检测方法,只需对电源电流和滤波器直流侧电压进行采样控制即可实现谐波补偿.对方案的双闭环控制系统进行了校正分析,应用Saber仿真软件对该方案进行了验证,并设计了实验样机.仿真与实验结果表明该方法可将谐波畸变率控制在10%以内.<abstract> order to eliminate the harmonic currents from the currents generated by electrical and electronic apparatus, the design method of a single-phase shunt active power filter (APF) based on the active energy balance was proposed. For it was difficult to measure the harmonics in single-phase system, the traditional method for harmonics measurement was abandoned. In this method, the harmonic wave compensation could be easily realized by sampling and controlling the source current and DC voltage of the filter. The double-closed control loop was emendated. The model of APF was built and simulated using the simulation software Saber, and an active power filter was designed. The simulated and experimental results indicate that the total harmonic distortion is less than 10%.
