| 摘 要： | 本文在分析瞬时无功功率理论亦即pq分解法中瞬时功率特征的基础上，提出了一种改进的谐波检测方法－数字积分滤波器。分析了该滤波器在各种供电系统中的性能，并通过对这一方法和传统的模拟低通滤波器的仿真比较，证明了该数字积分滤波器能提高谐波检测的精度，并满足实时性要求。

| Abstract: | Based on the characteristic of the instantaneous power in instantaneous reactive power theory,a improved harmonic detection method-digital integral filter is proposed.The performance of the filter is discussed at various power supply systems.By the simulation of MATLAB it is proved to be able to improve the accuracy of harmonic detection and meet the request of the dynamic compensation. |
