摘要

随着电网的发展

变电站的谐波问题已经从原来单纯来自于负荷发展为受系统电源和负荷共同影响的复杂问题

这也给变电站的谐波源定位带来了巨大的挑战。本文从谐波的有功功率和无功功率的方向出发

通过分析功率传递的物理过程

确定利用谐波功率的正负判断功率流向

并最终实现谐波源的准确定位。在此基础上

根据某220 kV变电站的谐波实际测试数据以及该站谐波情况的分析

利用该站主要次谐波的谐波功率计算

实现了该变电站谐波源的定位分析。

Abstract

With the development of the power grid

the harmonic problem of substation has developed from a simple load problem to a complex one affected by both system power and load

whichalso brings great challenges to the harmonic source localization of the substation. In this paper

staring from the active and reactive power of harmonics

the positive and negative harmonic power is used to judge the power flow through the physical process analyzing power transfer

and finally achieve accurate location of harmonic source. On this basis

the harmonic power calculation of secondary harmonic of a substation in accordance with the actual test data of harmonics and analysis of the harmonics of 220 kV substation so to achieve locationanalysisofharmonicsourceofthesubstation.
