Method for achieving fault isolation and recovery of power distribution network with permeability distribution type power supply

Abstract

A method for achieving fault isolation and recovery of a power distribution network with a permeability distribution type power supply belongs to the field of power distribution network operation management and is characterized by achieving fault isolation and recovery of the power distribution network with the permeability distribution type power supply on the basis of the intelligent distribution type feeder automation mode and is high in the intelligent degree and fast and accurate in judgment in the fault isolation and recovery process. The logical conditions can be modified and supplemented according to the practical topological structure of the power grid, and the whole control mode is based on the existing equipment and is not limited by the existing equipment. The various action logical conditions can be modified and supplemented according to the practical topological structure of the power grid along with continuous updating of the intelligent power grid equipment, so that computer simulation and fault trend analysis are facilitated, and guarantee is provided for scheduling and operation management of the power distribution network with the permeability distribution type power supply. The method can be widely applied to the field of scheduling, operation management and fault emergency treatment of the intelligent power grid.

Description

technical field [0001] The invention belongs to the field of operation and management of distribution networks, in particular to a fault isolation and recovery method for distribution networks. Background technique [0002] Since the 1990s, distributed power generation has developed rapidly. Many countries in the world have taken renewable energy as the basis of their energy policies. The development of distributed power generation has become a benchmark for sustainable development in all countries in the world. [0003] The development of distributed power generation in my country is relatively late. In recent years, clean energy distributed power generation has just started. In recent years, my country's distributed power has developed rapidly. [0004] At present, the massive and rapid development of distributed power generation poses severe challenges to national support policies and grid access support. [0005] As a large number of distributed power generation is con...

AI Technical Summary

Problems solved by technology

Because it is only limited to the traditional conventional relay protection system, and the purpose of its invention is to quickly remove the faulty distributed power supply, it does not observe and solve the problem from the perspective of the entire power distribution network, and lacks the overall power grid scheduling and management. Vision cannot adapt to the operation, scheduling and management level of the intelligent distribution network

[0010] As for the feeder automation FA (feeder automation) solution with distributed power, there is no development and application, and there is no application example in the power supply company
