This paper points out that three-phase real-time data that acquired by FTU and TTU can be resolved into three sequences of data and then state estimation can be made on each sequence of network to get the operation conditions of the whole network.

• 该文以此为出发点,将FTU、TTU采集到的三相实时数据分解为三序分量。 然后对每一序网做状态估计得到整个网络的运行状态。
