Study on State Estimation of Distribution Network Based on Load Current
Author(s): 
Pages: 70-73
Year: Issue:  4
Journal: ELECTRICAL EQUIPMENT

Keyword:  状态估计雅可比矩阵负荷电流支路电流;
Abstract: 基于负荷电流的配电网状态估计方法以负荷电流为状态变量,将支路测量函数用负荷电流表示,利用三相潮流计算方法得到支路电流的状态估计值,从而降低了状态估计问题的求解空间,提高了算法的收敛性和计算速度,通过将该算法与三相潮流计算法比较,结果表明状态估计算法在效果、速度、收敛性方面都较常规方法优越.
