A Distributed Distribution Network Fault Restoration Controller and Its Working Method

Abstract

The invention relates to a distributed power grid fault recovery controller and a working method thereof. The distributed power grid fault recovery controller is composed of a DSP chip, a power supply unit, a communication unit, an upper computer, a storage unit, an AD processing unit and a reset circuit. The power supply unit is connected with the DSP chip and the communication unit; the communication unit is connected with the DSP chip and the upper computer; the upper computer is connected with the communication unit and the power supply unit; the storage unit is connected with the DSP chip; the AD processing unit is connected with the DSP chip and the upper computer; and the reset circuit is connected with the DSP chip and the power supply unit. The provided controller has following beneficial effects: firstly, the equipment utilization rate is high, the distributed modularization access is realized, and the compatibility is high; secondly, the software pertinency and the execution efficiency are high; thirdly, the processor operation is in a high speed state and the real-time processing capability is strong; and fourthly, the peripheral external equipment has a simple structure, the technology is mature and stable, and the controller is easy to realize and control.

Description

technical field [0001] The invention relates to the field of distribution network operation control, in particular to a distributed distribution network fault recovery controller and a working method thereof. Background technique [0002] The complexity of the structure and scale of today's power grid and the increasingly high requirements of users for power quality make it necessary to recover efficiently and quickly after a fault occurs in the power grid to reduce the time and scope of power outages, thereby reducing power outage losses. With the application of the data acquisition and monitoring function SCADA (Supervisory Control And Data Acquisition) in the distribution automation system DAS (Distribution Automation System) in the grid operation, its monitoring, status indication, alarm, data telemetry and other functions can be used in the power grid accident state. Send real-time switch information and protection information to the dispatcher, and then perform rapid f...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a distributed distribution network fault recovery controller and its working method, which can overcome the shortcomings of the existing distribution network fault recovery operation, and can overcome the data provided by the SCADA system after the distribution network fault. There are relatively large limitations in solving the recovery scheme manually. With the help of the DAS platform, the substation and its power supply area are regarded as the smallest system, and the decentralized local processing scheme is adopted. After a fault occurs, the recovery scheme can be quickly given, which is flexible. , Distributed distribution network fault recovery controller with high reliability and wide application range, and a working method with high operating efficiency
