摘要
随着光伏渗透率的逐年增加,其接入对电能质量的影响日益显现。本文通过建立光伏电池、MPPT、DC/DC和逆变器等并网光伏发电系统数学模型,并基于Matlab/Simulink平台搭建了含分布式光伏发电的仿真模型,分析了光伏接入对电能质量的影响,并提出采用多功能在线监测装置改善电能质量。
With the increasing of distributed photovoltaics(PVs),the influence of the access on the power quality became more andmore.In this paper,mathematics models of photovoltaic cell,MPPT,DC/DC,and the inverter etal were set up.Also the simulating modelswere set up based on Matlab/Simulink.The influence on power quality was analyzed and the countermeasures were given.To improve thepower quality,adopting multi-function online monitoring devices was provided.
