中文摘要：

采用利用支路参数的状态估计法辨识网络拓扑错误。引入支路参数表示支路运行状态,并将其作为参数变量扩展进传统最小二乘状态估计模型中的状态变量中,通过构造新的目标函数求解参数估计值,根据参数估计值大小判断支路运行状况。所述方法在试验系统上进行了试算。

英文摘要：

State estimation method of branch parameter is employed in this paper to identify the network topology errors. This paper introduces the branch parameter which represents the operation condition of branch,and takes it as parameter variables expanded into the conventional state estimation model of least square method,which composes the minimum problem of objective function,and the operation conditions of topology structure is judged according to the estimation value of branch parameter. The mentioned algorithm is tested on an actual testing system.
