摘要
基于瞬时无功功率理论的谐波检测算法基本原理,提出该理论的ip-iq谐波检测算法的改进方案———直流分量法。通过理论推导并在Simulink仿真环境中进行的建模仿真实验表明:直流分量法比传统的滤波器法具有更好的动态响应特性。
A modified method for harmonic detecting -- DC component is proposed based on instantaneous reactive power theory. By theoretical derivation, the results of simulation examples for DC component verify a faster transient response than using conventional filters.
