Fault recorder power supply restarting device based on wireless network and control method thereof

Abstract

The invention discloses a fault recorder power supply restarting device based on a wireless network and a control method thereof. A power supply module of the device supplies power to each module; the communication control module is used for receiving an instruction for remotely restarting the fault oscillograph and carrying out communication; the single-chip microcomputer module is used for receiving signals sent by the communication control module and controlling the node control relay module to work. The node control relay module is controlled by the single-chip microcomputer module and controls the restart of the fault recorder. The communication control module is connected with the single-chip microcomputer module, and the single-chip microcomputer module is connected with the node control relay module. The fault oscillograph power supply restarting device based on the wireless network is convenient to install, simple in control process and high in safety coefficient, whether restarting is needed or not is determined by judging the operation state of the oscillograph, the number of times of hard restarting is reduced, hardware damage caused by frequent restarting of the fault oscillograph is avoided, and the service life of the fault oscillograph is prolonged.

Description

technical field [0001] The invention belongs to the field of fault recorders, and in particular relates to a wireless network-based fault recorder power restart device and a control method thereof. Background technique [0002] The fault recorder is an important automatic device to improve the safe operation of the power system. It is mainly used to automatically and accurately record the changes of various electrical quantities in the process before and after the failure when the power system fails. Through the analysis and comparison of these electrical quantities , to help scheduling, operation and maintenance and maintenance personnel to judge and analyze the nature of the fault and the action behavior of the relay protection device, effectively improving the safe operation level of the power system. With the continuous improvement of automation level, the types of power system faults and the complexity of action situations are increasing, and fault recorders are playing...

AI Technical Summary

Problems solved by technology

The failure of the fault recorder will not only affect the assessment results of the provincial commissioner on the connection rate of the fault recorder and the success rate of record retrieval, but also if a trip accident occurs during the failure of the fault recorder, the fault recorder will not be able to accurately record Fault waveforms, which affect fast and accurate fault analysis
