摘要
目前国内的配电网主要是中低压类型,不能同时接入大量光伏发电系统,否则会超出中低压配电网的容纳限度,导致配电网的实际电流运行方式产生变化.如果光伏发电系统接入数量超过配电网的安全运行限度,会对配电网的正常运行产生影响,甚至造成严重的安全事故.基于此,主要从分布式光伏发电并网对配电网安全带来的影响入手,分析了我国目前所使用的一些解决方法.
Abstract
Currently,the distribution network in China is mainly of the medium-and low-voltage type and can not access a large number of the photovoltaic power generation system simultaneously,or it will exceed the capacity limit of the medium-and low-voltage distribution network,leading to changes in the actual current operation mode of the distribution network.If the number of access to the photovoltaic power generation system significantly exceeds the safe operation limit of the distribution network,it will have an impact on the normal operation of the distribution network and even cause serious safety accidents.Based on this,the article mainly starts with the impact of the grid connection of distributed photovoltaic power generation on the safety of the distribution network,and analyzes some solutions currently used in China,for reference.
