摘要
为保证10k V配电网合环转供电的安全性,需对合环电流的计算方法进行研究。针对10k V配网合环风险,给出了网孔等值法计算合环稳态电流的方法。结合电网实际接线方式对合环方式进行分类,并统计了各种方式的合环成功率分布情况,给出了合环操作基本原则,提出了不同的合环方式相应的实用指导原则。基于调度实时数据,开发的合环计算程序可以解决单次合环电流的精确计算。基于历史数据库数据,提出的合环计算管理软件可实现地区电网合环点的批量管理。
To ensure the security of 10 k V distribution network loop closing,the calculation method of the loop closing current must be studied.Based on the loop closing risk for 10 k V distribution network,a method to calculate the loop closing current by mesh equivalent method is proposed.The closed loop modes of Dongguan power grid is classified,and the loop closing success rate is counted.Finally,the closing loop operation guidelines and practical suggestions is presented.Combined with the scheduling real-time data,the developed loop closing calculation program can accurately calculate the single loop closing current.With the historical database data,the loop closing calculate management software can batch manage the regional power grid loop closing points.
