Intelligent distribution network self-healing control method based on fault-tolerant thought

Abstract

The invention provides an intelligent distribution network self-healing control method based on a fault-tolerant thought. According to the intelligent distribution network self-healing control method, an association relationship between the effect expressed in a system of each set of equipment in an actual distribution network and the equipment is analyzed, and an operation state of the distribution network is combined to divide the distribution network into a current function resource which is operated at present, a redundant resource capable of being called and a path unit, so that a distribution network resource structure network model is established; when the operation of the distribution network is in an early warning state, the redundant resource needs to be put into operation; once if the redundant resource slips off to an emergency state or a critical state, the system rapidly controls the path unit, and the redundant resource is accessed into the distribution network, so that the operation state of a power grid is improved and the power grid is prevented from being worsened and entering a fault state; and a distribution network resource structure is flexibly converted, and then foundations are provided for fault-tolerant control of the distribution network, so that the reliability of the distribution network is effectively improved and the emergency capability is enhanced.

Description

technical field

[0001] The invention relates to the technical field of electric power intelligent control, in particular to a self-healing control method of an intelligent distribution network based on the idea of ​​fault tolerance. Background technique

[0002] "Self-healing" refers to isolating the problematic components in the power grid from the system, and prompting the system to quickly return to normal operation with little or no human intervention, so as to achieve continuous and uninterrupted power supply services to users. Since the distribution network is directly oriented to users, it concentrates the most important load, involves the political and economic lifeline of the country, and is related to thousands of households. Once a power failure occurs in the distribution network, it will cause huge impact and loss. Constructing a self-healing smart distribution network with self-perception, self-diagnosis, self-decision-making, and self-recovery capabilities is o...
