Abstract

The invention relates to the field of an electric power system, and discloses a method for restoring self-growth. The method is based on a power distribution terminal which monitors a power distribution line and is used for analyzing the information of the power distribution line in real time. After a fault occurs, fault information is successively transmitted to a tie switch power distribution terminal from a fault point power distribution terminal. The tie switch power distribution terminal starts restoring of a non-fault area. Directly monitored areas are successively analyzed. According to a line operation topology, self-growth analysis is performed until the area where power supply can be restored. The terminal which directly manages the switch bypasses the switch and insulates the area which requires power supply restoring. Furthermore a terminal which directly manages the tie switch switches on the tie switch, thereby finishing power supply restoring to the non-fault area.

Description

technical field

[0001] The invention relates to a power supply recovery control method in the technical field of power systems, and is mainly used for controlling power supply recovery in non-faulty areas when a power distribution network fails. Background technique

[0002] There are a certain number of distribution terminals in the distribution line to monitor the operation of the distribution line. Traditional power distribution lines adopt centralized control to restore power supply to non-faulty areas after a fault. That is, when a permanent fault occurs in the distribution line, the distribution automation master station or a terminal with centralized control mode collects the fault current data of each distribution terminal in the distribution line, and then judges the location of the fault point according to the fault characteristics of the distribution line , to realize fault location, and then send a control command to the power distribution terminal, wait for the...
