Abstract

The invention discloses a method for researching and judging a power outage fault in a distribution network. Overall path matrix; judge the distribution of ant colony to determine the sub-path matrix of ant colony search, and use it as a sub-pheromone matrix; use ant colony algorithm to search for faults, search for paths for all ants in the ant colony, and update them synchronously The element value of the sub-pheromone matrix; all ants have been judged as the termination condition, and the maximum value of the element in the sub-pheromone matrix is ​​the power failure point. The invention improves the speed and accuracy of fault location, shortens the response time, reduces the cost, and improves customer satisfaction and system operation indicators without increasing hardware investment cost.

Description

technical field

[0001] The invention relates to a method for researching and judging a power outage fault of a distribution network, and belongs to the technical field of distribution networks. Background technique

[0002] Since the introduction of the smart grid in 2009, my country has comprehensively promoted the construction of smart distribution networks, and the automation level of the grid has been continuously improved. At the same time, users have raised higher requirements for the reliability and quality of power supply services. Positioning has also become a hot spot of research attention.

[0003] For a long time, for low-voltage side fault information, the power supply company has mainly used the repair calls of residents, used the power outage management system to handle low-voltage lying network faults, and predicted the location of the drop insurance or switch based on the calls made by users after the power outage. Analyze the personnel strength and emergenc...
