摘要
以1座光伏电站接入系统后,在其电力送出网络中第一落点变电站2台主变压器中1台发生故障时存在的过载问题为例,进行了N-1故障校验分析。提出采用在电网相关厂(站)装设安全自动装置的措施,并给出具体装置配置方案及控制策略,以解决地区电网在新能源电力接入系统后N-1故障情况下的主变压器过载问题。
Based on the intergration of a photovoltaic power station which facing theproblem of transformer overload when either of the two transformers in access substationbreaks down, make an analysis of N-1 fault checking. Then proposes the mearsure whichinstalls automatic safety devices in related stations and gives out specific configurationscheme of device and control strategies, which can solve the problem of transformeroverload under N-1 principle caused by renewable energy′s access grid effectively.
