电网单点等值下等效谐波参数计算
Equivalent harmonic parameters calculation at single point of power grid
摘要
Abstract
In this paper , a method is proposed to calculate the parameters of the equivalent system in power grid such as the equivalent harmonic voltage and the equivalent harmonic impedance .The method makes every five sampling points as a set to linear regression based on complex field to achieve the harmonic voltage of equivalent circuit and har -monic impedance parameters of the equivalent system , and then the single-point equivalent model of grid is built .This method is featured with high accuracy and good stability .The accuracy of the proposed method is verified by the simu-lation of IEEE14-bus system based on PSCAD/EMTDC software .关键词
