Problems solved by technology

In this way, the selectivity of fault isolation through the self-healing control unit is not strong. It will take a long time to blindly disconnect all the switches around the fault point, and then restore the power supply in the non-fault area. Communication reliability is also required to be high

Abstract

The invention discloses a panoramic perception self-healing system and method for a power distribution network. The system comprises a sampling module, a communication module, a fault isolation module, a self-healing gate module and a backup protection module. The method comprises the following steps that: the self-healing terminal acquires analog quantity, switch state and operation information of each accessed interval in real time; a plurality of self-healing terminals are connected to form a looped network, and data sharing is performed on analog quantity, on-off states and operation information in the looped network; when a fault occurs in the protection range of the self-healing terminal, the fault area is isolated; carrying out a self-healing charging function, checking the voltage condition of a fault side, and supplying power when the voltage is abnormal; and when the power distribution network has an abnormal phenomenon after fault isolation or power supply recovery, a protection function is started. According to the invention, the fault isolation and the self-healing gate can be carried out on the local terminal, and the purposes of real-time decision making and rapid control are achieved.

Description

technical field [0001] The invention relates to the field of distribution network monitoring, in particular to a panoramic perception self-healing system and method for distribution networks. Background technique [0002] Power distribution is an important part of the power system. It directly faces power users and undertakes power supply services for power users. With the rapid and healthy development of the national economy and the continuous improvement of the people's material and cultural living standards, people have higher requirements for the reliability of the distribution network and the quality of power supply. Effectively reducing the power outage time is the key to improving the user's power consumption experience. index. At the same time, it will be the future development trend to realize the panoramic perception, flexibility, security and controllability of the power distribution network. [0003] There are a certain number of intervals in the distribution n...
