Distribution network distributed loop closing intelligent error prevention system and its implementation method

Abstract

The invention discloses a distribution network distributed loop closing intelligent error prevention system, which includes a hand-held intelligent configuration machine, an intelligent power distribution terminal, an intelligent power distribution loop closing terminal, and a communication network. The communication network includes a wireless communication network and an optical fiber communication network. The handheld intelligent configuration machine is connected to the intelligent power distribution loop closure terminal through the wireless communication network, and the intelligent power distribution loop closure terminal is connected to the intelligent power distribution terminal through the optical fiber communication network. The present invention also proposes an implementation method of the distributed network closing intelligent error prevention system, including: step SS1 configuration of the loop closing error prevention rule library, including: configuration of the loop closing error prevention rules, and automatic generation of the loop closure error prevention rule library Downloading of the anti-mistake rule library of Hehehuan; step SS2 distributed anti-mistake operation, including analysis of the anti-mistake rule library, real-time interaction of anti-mistake information and execution of anti-mistake operation. The invention realizes the real-time logical judgment of distributed ring closure and error prevention.

Description

technical field [0001] The invention relates to a distributed loop-closing intelligent error prevention system for a distribution network and an implementation method, belonging to the technical field of distribution networks. Background technique [0002] With the development of distribution network construction, my country's distribution network has generally adopted a two-way power supply mode. The biggest feature of the distribution network is the closed-loop structure and the power supply mode of open-loop operation. Under normal circumstances, the contact switch generally operates on and off. When the load is reversed or the line is overhauled, the power outage time can be reduced and the reliability of power supply can be improved by closing and breaking the loop operation. sex. However, the loop closing operation will generate a loop closing current, which may cause protection malfunction or even cause accidents. [0003] The existing loop closure method of the mas...
