摘要
一些大规模的光伏电站接入配电网,导致原先的单端配电网逐渐转变为双端甚至是多端的供电性网络,这会引起配电网中的潮流分布出现一定的变化.当出现短路故障时,会发生继电保护的误动和拒动,对配电网的安全运行造成很大的影响.为此,分析研究了光伏新能源并网对继电保护带来的影响,并采取有效措施来提高光伏发电的效率,确保并网的质量.
Abstract
Some large-scale photovoltaic power stations are connected to the distribution network,leading to the gradual transformation of the original single end distribution network into a dual end or even multi end power supply network,which will cause certain changes in the power flow distribution in the distribution network.When a short circuit fault occurs,the misoperation and rejection of relay protection will occur,which will have a significant impact on the safe operation of the distribution network.To this end,the impact of photovoltaic new energy grid connection on relay protection was analyzed and studied,and effective measures were taken to improve the efficiency of photovoltaic power generation and ensure the quality of grid connection.
