摘要
根据瞬时无功功率理论基础,基于传统的ip-iq算法在谐波检测中其动态响应及精度上的不足,对其低通滤波器(LPF)进行改进,增加了平均值滤波算法。理论分析及Matlab仿真实验表明,改进后的谐波检测方法具有较快的动态响应与良好的检测精度,具有较高的应用与研究价值。
According to the basis of the instantaneous reactive power theory, based on the insufficiency of dynamic response and precision in traditional ip-iq algorithm which used in harmonic detection, the low-pass filter(LPF) was improved and the average filtering algorithm was added. Theoretical analysis and Matlab simulation results show that the improved harmonic detection method has faster dynamic response and good detection precision, and has higher application and research value.
