Due to the actual fact of weak measurement configuration and incomplete information in distribution network, the comprehensive utilization of real-time data of the distribution network and the main network,quasi real-time data of distribution transformer,electricity data of marketing system,historical data,load forecasting data,and typical load characteristics are used to realize the distribution network state completion.The research contents include topological analysis,measurement data preprocessing to eliminate the unreasonable data,analysis of observability,load data calibration and complete of distribution network,switch measurement completion of distribution network.It has high practical value for distribution network normal operation and management,ensuring the distribution management system to work as intended.
