摘要
针对当前配电自动化可靠性评估过程中,故障研判和开关控制考虑不全面的情况,提出了一种基于终端配置影响关系的可靠率算法。将馈线根据用户信息拆分为馈线基段,依据终端配置位置确定馈线分段关系矩阵和馈线基段影响矩阵,代入故障处理相关参数得出结果。模拟计算了架空线路的三种终端配置方案,结果表明该算法能够有效求解复杂网架结构下不同终端类型和位置条件下的可靠率,为配电自动化终端配置方案的选择提供参考依据。
Aiming at the problem exiting in reliability assessment of distribution automation,in which fault diagnosis and switch control is not comprehensive enough,a reliability rate assessment algorithm based on terminal configuration influence relationship is put forward in this paper.The feeder is split into base segment,and then,feeder segmentation relationship matrix and feeder base segment influence matrix are determined according to terminal configuration location.Then,the solution value is obtained.Three terminal configurations of overhead lines are simulated and calculated.Simulation result shows that the proposed method can effectively solve the reliability rate with different types and locations in complex network structure,which provides reference for the selection of distribution automation terminal configuration schemes.
