Embodiment Construction

[0035] Such as figure 1 As shown, the method for handling the fault of the distribution network equipment in the present invention includes.

[0036] S1. Configure terminal association information.

[0037] (1) Establish a directed association list for each terminal, which includes all adjacent terminals connected to the terminal with feeders, including all forward terminals, backward terminals and parallel terminals associated with the terminal, wherein the The direction of the feeder current from the forward terminal to this terminal is the same as the direction of the feeder current from this terminal to the next terminal, and the direction of the feeder current from the backward terminal to this terminal is opposite to the direction of the feeder current from this terminal to the next terminal. The parallel terminal has the same backward terminal as this terminal.

[0038] (2) Determine the power flow direction of the whole network. For a network with multiple power sour...

Abstract

The invention discloses a power distribution network equipment fault processing method. The method comprises the steps of terminal association information configuration, power distribution network fault recovery and terminal load recovery. According to the power distribution network equipment fault processing method, the automatic operation level is high, remote control and real-time detection can be achieved, fault detection and isolation are automatically completed through joint debugging of feeder line equipment based on associated configuration of the equipment, and rapid recovery of equipment loads is achieved through an optimized load recovery strategy.

Description

[0001] This application is a divisional application. The original application is an invention patent titled "A Method for Troubleshooting Distribution Network Equipment". The application number of the original application is "2020107974768", and the application date is August 10, 2020. technical field [0002] The invention relates to the field of distribution networks, in particular to a method for processing faults of distribution network equipment. Background technique [0003] When a fault occurs in the distribution network, how the distributed power supply operates will directly affect the implementation of the fault recovery strategy. When a fault occurs, when the power grid including equipment such as terminals or local devices is separated from the public power grid, the power grid will perform island operation . [0004] The existing management method is relatively chaotic and lacks relevance for the management of industrial equipment, which leads to a passive respo...
