摘要
有源电力滤波器是用于对电力系统谐波、无功及负序电流进行动态综合补偿的装置,其中的谐波电流检测电路是决定补偿性能好坏的重要环节。以三相电路的瞬时无功功率理论为基础,对改进型的检测方法进行了理论分析。通过MATLAB进行仿真研究,仿真结果表明:采用该方法的滤波器可以实时地检测和滤除谐波。理论分析和仿真结果都证明了该方法的正确性。
Active power filter is a kind of device used for dynamic comprehensive compensation of the harmonics of power system, reactive power and negative sequence current, in which the detection circuit of harmonic current is an important point which decides the compensation performance. In this paper, the theoretical analysis for the modified detection method is performed on the basis of transient reactive power theory of three phase circuit. The simulation study is made through MATLAB, showing that filter with the method can real-time detect and eliminate harmonies. The correctness of the method is verified by both analysis and simulation results.
