Abstract

The invention discloses a self-healing recovery method for a fault of a tail end power distribution network of a mountainous area, which considers power distribution network frequency stability and load importance degree. An electric power system is related to national welfare and the people's livelihood, and optimization of a self-healing recovery method of a tail-end power distribution network is crucial for maintaining safe and stable operation of the electric power system. According to the self-healing recovery method, all feasible solutions configured by all feasible initial switches are traversed, and the self-healing recovery method with the lowest self-healing recovery cost is found. The requirements of power system frequency stability and important load priority recovery in the self-healing recovery process are considered, and the method is of great significance in guaranteeing safe and stable operation of the power system.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a fault self-healing recovery method for terminal distribution networks in mountainous areas. Background technique [0002] The power system is related to the national economy and the people's livelihood, and it is very important to maintain the safe and stable operation of the power system. When the terminal distribution network causes a major blackout due to accidents such as typhoons, in order to quickly restore load power supply and reduce social and economic losses, it is necessary to optimize the self-healing recovery method of the terminal distribution network. Contents of the invention [0003] The purpose of the present invention is to provide a fault self-healing recovery method for a terminal distribution network in a mountainous area, which can effectively solve the problem that the fault of the existing terminal distribution network cannot be self-he...
