| 摘 要： | 本文针对PMU技术以及当前WAMS和SCADA系统量测并存的现状,研究基于PMU的状态估计算法。首先在动态估计中利用PMU量测进行边界协调;然后利用滤波步得到的状态变量值和PMU量测值进行一次线性估计,将非线性动态估计和线性估计结合起来,最大限度利用了PMU数据。

| Abstract: | In this paper, PMU and WAMS technologies, as well as the current SCADA system measuring the status of both , Study of the PMU- based state estimation algorithm. First of all, the use of estimates in the dynamic measurement PMU to carry out border coordination; Step-by-step and then the use of filtering received PMU state variable value and a measured value of the linear estimates, Will be non-linear and linear dynamic estimate estimate combining data to maximize the use of the PMU. |
