Problems solved by technology

Once the 35kV power supply of the medium and low voltage power distribution system has a permanent failure due to natural disasters, man-made damage or equipment failure, etc., it will often cause a large area of ​​power loss in the power distribution area, resulting in a series of serious consequences
At present, there are few studies on how to quickly and effectively restore power supply when power failures in urban medium and low-voltage distribution networks, especially 35kV power failures, cause large-scale power outages.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of power system automation and low-voltage power supply failure recovery control in an intelligent distribution network, in particular to a recovery system and method based on a 35kV power supply failure in an intelligent distribution network. [0003] (2) Technical background [0004] With the rapid development of urban modernization, the complexity of urban power distribution systems and users' requirements for power supply reliability are getting higher and higher, showing the characteristics of many branches, small power supply radius, dense load, and complex structure, which greatly increases The difficulty of recovery after a distribution network failure. In recent years, with the country's emphasis on smart grids, smart distribution network technology has been greatly developed, and the automation level of urban distribution networks has gradually improved. A large number of data acquisition...
