摘要
基于当前国内风力发电场运行现状,本文对风电场的集电线路能够带多少箱变进行倒送电而不导致线路跳闸的数量问题进行了分析研究。通过对某风电场箱变的励磁涌流及继电保护配置分析,给出了思路和计算方法。最终得出继电保护不动作情况下最多能够带多少箱变进行倒送电。
Based on the current status of wind farm operation in China,this article analyzes how many transformers can be carried when the line is powered up without causing the line to trip.This paper analyzes the inrush current of the transformer and relay protection configuration of the wind farm,in addition,the ideas and calculation methods are also given.Finally,it is concluded that the maximum number of transformers can be carried if relay protection does not trigger.
