小容量光伏发电系统接入配电网的电压特性分析
Analysis of Voltage Characteristics of Small Capacity Photovoltaic Power Generation System Connected to Distribution Network
摘要
Abstract
Aiming at the changes in voltage distribution and even overvoltage exceeding limits caused by the access of a large number of distributed photovoltaic(PV)power generation systems into the distribution network,which can lead to a reduction in the reliability,stability and security of power supply of the distribution network in serious cases,the author investigates the relationship between the transmission line voltage distribution and the installed capacity and location of the PV power system by mathematical modelling method,and carries out the argumentation analysis by building example method.The results show that voltage exceeding may occur in transmission lines after the installing site of PV power generation systems,and voltage exceeding may also occur when the installed capacity is large.关键词
