摘要

针对实际工程中谐波功率计算时由于电压互感器引起的不利影响

本文提出一种计及电压互感器影响的谐波视在功率概率密度函数计算方法。该方法通过150周波有效值概率密度函数推算得出10周波有效值概率密度函数。通过视在功率与电压、电流的关系

得出视在功率概率密度函数

并在视在功率表达式中加入电压互感器的影响系数。仿真数值及实测数据分析表明了该方法的可用性。

Abstract

As for the unfavorable effect due to voltage transformer in the harmonic power calculation of the actual project

in this paper

a kind of method to deal with influence of voltage transformer on harmonic apparent power calculation using probability density function is proposed.The 10-cycle probability density function r.m.s.is derived with this method through that of 150-cycle.The apparent power density function is obtained through the relationship between the apparent power and voltage as well as current and the influence coefficient of voltage transformer is added in the apparent power expression.The applicability of the method is shown by the simulation value and the actually measured data.
