| 摘 要： | 本文提出了一种新的快速耦配电网状态估计算法。算法采用加权最小二乘估计模型。在等效电流法的基础上引入旋转操作从而使雅可比国和信息矩阵解耦。因为雅可比矩阵完全解耦，所以信息矩阵的解耦是严格的。仿真算例表明该方法在收敛速度和估计精度上均优于等效电流法。

| Abstract: | A new fast decoupled state estimation method is presented for distribution systems. The weighted least square(WLS) approach is used.The equivalent current based formulations are introduced first and then the rotational operator to the state and measurement functions resulting in a decoupling of the Jacobian and gain matrices is discussed. The decoupling of the gain matrix is rigid due to the decoupling of the Jacobian matrix. Digital simulations indicate that the method is better than the current-based method in terms of convergence time and accuracy. |
