摘要
针对分布式状态估计问题,采用基于相量测量单元(PMU)和灵敏度矩阵修正的方法。利用PMU量测量来协调子系统参考节点,并通过修正子系统独立状态估计联络线上的状态量,得到联络线上支路功率变化量,利用支路功率变化量对节点状态量的灵敏度矩阵来修正子系统状态估计结果。以IEEE14节点为例进行仿真,结果验证了该算法的有效性。
PMU and sensitivity matrix modification method were adopted according to distribution status estimation. PMU measuring was applied to coordinate sun system reference node. Power vibration in connecting line was obtained by modifying the independent status of subsystem. The validity of thealgrothm was proved by the case of simulation on IEEE 14
