摘要

谐波谐振严重危害配电网的安全可靠运行

合适的谐波谐振分析方法十分重要。传统模态分析法是分析电网谐波谐振的一种主要方法

能够获得谐振的各种信息

如谐振频率、最高激发点、最高观测点以及参与因子

但其计算效率较低

且无法准确判断配电网谐波谐振中的最高激发节点。本文提出的改进模态分析法将频谱分析法与传统模态分析法相结合

增加了判断激发节点在谐振频率下能否发生谐振的条件。仿真结果表明

本文提出的方法能够高效准确地确定出配电网谐波谐振频率和最高激发节点。

Abstract

Harmonic resonance endangers seriously safe and reliable operation of grid and an appropriate resonance harmonic analysis method is of great importance. The traditional mode analysis method is a kind of main method to analyze harmonic resonance of grid so to obtain various harmonic information such as resonance frequency

maximum excitation node and observation node as well as participation factor. However

its calculation efficiency is lower and has no way to judge accurately the maximum excitation node in the harmonic resonance of the distribution grid. The improved mode analysis method proposed in this paper combines the frequency spectrum analysis with the traditional mode analysis method

and the condition whether the judgment excitation node can occur resonance at resonance frequency is added. It is shown by the simulation result that the method proposed in this paper can effectively and accurately determine harmonic resonance frequency and maximum excitation node of distribution grid.
