摘要
提出了一种基于等效电阻概念和功率平衡原理的串联型有源电力滤波器(APF),新串联型有源电力滤波器不需要进行复杂的谐波检测计算,通过简单的控制就可以获得电源电流的参考信号,实现对谐波和无功电流的同时补偿。研制了实验样机,实验结果与理论分析和仿真结果相吻合,验证了所提出控制方法的正确性,并显示所提出的串联型APF对电压型谐波源有良好的补偿特性。
A novel series active power filter control method based on the principle of equivalent resistor and power equilibrium is proposed in this paper. The new control method can be implemented with very simple circuit, doesn＇t need to take harmonic detection and complex computation. And the harmonic and reactive current can be compensated simultaneous. Based on the theoretical analysis and simulation research, a single-phase series active power filter proto type employing the proposed control method is designed. The experiment results meet with the simulation results, and confirm the validity of theoretical analysis. The experiment results indicate that this control method has good compensation performance. The series active power filter with the proposed control method is a simple low cost scheme for power harmonic suppression.
