| 摘 要： | 电力系统状态估计作为一种高及应用软件，在整个能量管理系统中起着非常重要的作用。本文在对已有状态估计方法进行分析的基础上，并考虑了实际电网的一些特点，提出了一种将电压量测量和功率、电流量测量分解开来进行计算的加权最小二乘法状态估计算法。研究了该方法在微机ＤＯＳ平台上的实现，和其他方法进行了比较，认为该方法具有收敛性好，计算速度快的优点。

| Abstract: | As a kind of power advanced application software, power system state estimator play a important role in the power management system.The shesis analyzed the state estimation method which are exited, taking account of the distribution system, then proposed a new weighed least spuare state estimation method ,which break down the measurement, one is the voltage measurement, the other is the power or current measurement .It also discussed the realization of the method on the DOS platform of the personal computer ,and compare with the basic WLS method. We think the new method is suitable for the distribution system state estimation as the high computing efficiency and well convergence. |
