摘要
电网发生故障时 ,根据断路器跳闸信息和母线电压信息 ,采用 BFS(广度优先搜索 )的方法搜索出故障区域。基于故障区域建立保护和故障设备之间关系的数学模型 ,将故障诊断问题表示为 0 -1整数规划问题。在目标函数中引入贡献因子 ,通过遗传算法诊断出故障设备。实例表明所提模型是正确的 。
When a fault occurs in a power system,fault area is located using Broad First Search(BFS) method by breakers and bus voltage message.The mathematics model which reflects the relation between the relay and fault equipment is established,and fault diagnosis problem is converted to optimization problem.Contribution factor is introduced in goal function.Genetic algorithm is used to solve optimization problem. Emulation indicates this scheme is feasible.
