摘要
提出了 1种基于dq理论的改进型谐波提取方法 ,该方法成本低、检测精度高、主要部件参数对谐波检测精度的灵敏度低。传统的检测方法做了比较 ,对 2种方法的各主要参数使用SABER软件进行了灵敏度分析和Monte Carlo分析。最后将这 2种方法应用于一串联型混合有源滤波器 。
An improved harmonic detecting method is presented on the basis of the conventional approach using dq rotating coordination transformation.The detail comparison of the improved approach and the conventional method is performed through sensitivity analysis and Monte Carlo analysis by using software saber. The simulation results indicate that the detecting precision of the improved approach is much higher than that of the conventional method. The analysis results are verified by a simulation prototype of a 56 kVA three phase active power filter.
