基于QR-RLS算法的自适应配电网谐波电流检测
摘要：电力有源滤波器对配电网中谐波的治理起着重要作用,而电力有源滤波器的核心是谐波电流检测算法。为了提高谐波电流检测的有效性,本文提出了基于QR分解的递归最小二乘(QR-RLS)算法的自适应配电网谐波电流检测,该方法能够准确地把基波电流和谐波电流分离出来。本文通过PSCAD/EMTDC仿真软件建立仿真电路得到电路中的电流数据,仿真数据和实测数据的分析结果证明了该算法的有效性。
Abstract:Active power filter plays important role to manage the harmonic currents of distribution network, while the key issue is harmonic current detection algorithm. In order to improve the effectiveness of the harmonic current detection, an adaptive harmonic current detection method is put forward based on QR-RLS algorithm, which can accurately separate the fundamental currents and harmonic currents. In this paper, the simulation circuit is built by PSCAD / EMTDC software to obtain the current data. And the analysis of simulation data and measured data verifies the effectiveness of the algorithm.
