光伏电站接入宁夏电网的系统谐波评估实用计算

摘要

In order to use solor energy better,the design period needs to make harmonic evaluation before the photovoltaic substation connecting into power system and assure the connection of photovoltaic substation has less effect on power energy quality of the system.Uses the electric power system integrated analysis software to make modeling,evaluates the photovoltaic substation connecting into power system.the calculation results shows： the connecting points of the photovoltaic substation all accord with the demands and allow to connect into the power system.%为保障现有电网的安全稳定,更好利用太阳能,在光伏电站接入系统前的设计阶段需对光伏发电接入系统进行谐波评估计算,以确定光伏电站的接入对系统电能质量不造成大的影响。本文采用电力系统综合分析软件进行建模,对即将接入系统的光伏电站进行评估计算,计算结果表明：光伏电站接入点符合要求,允许接入系统。
