Abstract

The invention discloses a power distribution network fault monitoring system and method based on multi-source measurement data, and the system carries out the layer and domain partitioning of the obtained multi-source measurement data through a multi-source data partitioning module, and obtains the partitioning data corresponding to different partitioning types. The multi-source data fusion moduleis used for carrying out fusion processing on the division data of different division types according to the division types to obtain fusion data of different fusion types; the fault identification module selects a corresponding fault identification unit to perform fault identification on the fusion data according to the fusion type to obtain a fault identification result; and the fault processing module is used for obtaining a fault identification result, processing the fault identification result according to a preset fault processing mode and sending processed information to the monitoringprotection platform, so that the measurement data is effectively utilized to monitor the fault of the power distribution network, the detection accuracy is improved, and the power distribution network is safely and effectively monitored and protected.

Description

technical field [0001] The invention relates to the technical field of power systems and automation thereof, in particular to a distribution network fault monitoring system and method based on multi-source measurement data. Background technique [0002] With the continuous maturity of power electronics technology and new energy generation technology, more and more distributed power sources are connected to the distribution network, which greatly increases the complexity of the distribution network method, making the distribution of power flow and post-fault problems in the distribution network The current characteristics have changed. With the continuous improvement of distribution automation methods, a large number of intelligent terminals such as FTU (Feeder Terminal Unit, feeder monitoring terminal), DTU (Distribution Terminal Unit, distribution terminal unit), TTU (TransformerTerminal Unit, distribution transformer monitoring terminal), RTU (Remote Terminal Unit, remote...
