分布式光伏接入配电网的主电路可靠性分析

Reliability Analysis of the Main Circuit for Distributed Photovoltaic Access to Distribution Networks

随着分布式光伏越来越多接入配电网,对分布式光伏接入配电网的主电路可靠性分析具有重要意义。本文首先研究了光伏接入配电网的原理,接着研究集中式逆变器和组串式逆变器两种经典的分布式光伏接入配电网的主电路架构,并分别分析了可靠性指标。最后的算例计算了同等容量下的分布式光伏的可靠性数值。

As more and more distributed Pv is connected to the distribution network,it is of great significance to analyze the reliability of the main circuit of distributed PV to the distribution network.This paper first studies the principle of photovoltaic access to distribution network,then studies the main circuit architecture of two classical distributed photovoltaic access to distribution network,and analyzes the reliability index respectively.Finally,the reliability of distributed Pv with the same capacity is calculated.
