Intelligent management system for digital medium-voltage switchgear of power plant

Abstract

The invention provides an intelligent management system for digital medium-voltage switchgear of a power plant. The system comprises a programmed operation module which is used for enabling the switchgear to execute a programmed instruction, a visual monitoring module which can remotely monitor the actual conditions of each circuit breaker and each grounding switch; an asset health management module which is used for providing equipment health diagnosis results and targeted equipment maintenance suggestions for users; and an arc fault rapid protection module which improves the safety performance of the system. The intelligent management system for the digital medium-voltage switchgear of the power plant can realize unified and centralized management of operation control of the medium-voltage switchgear, realizes remote inspection of the medium-voltage switchgear, is high in visualization degree, can realize online monitoring and analysis and diagnosis of the health state of the medium-voltage switchgear, and improves the safety of the medium-voltage switchgear; potential defects possibly existing in equipment are found in advance and eliminated in time, and an innovative arc faultrapid protection module is arranged, so safe and stable operation of the system is ensured.

Description

technical field [0001] The invention relates to an intelligent management system, in particular to an intelligent management system for digital medium-voltage switchgear in a power plant. Background technique [0002] Medium-voltage switchgear is widely used in power supply and distribution systems of power users, mainly for power distribution, control and protection functions. In recent years, with the rapid development of power supply technology, my country's power supply grid has achieved unprecedented improvement in terms of hardware facilities and software management of the grid. Smart grids have gradually entered my country's power system. A large number of medium-voltage switchgears are How to realize the intelligent management of medium-voltage switchgear, which is an important power supply infrastructure equipment of the power grid, has become an urgent problem in the industry. [0003] In the prior art, the management of medium-voltage switchgear mainly has the fol...

AI Technical Summary

Problems solved by technology

[0004] 1) There is a lack of unified and centralized management of the operation and control of medium-voltage switchgear, and the remote inspection of medium-voltage switchgear cannot be realized, and the operation and maintenance efficiency of the power supply and distribution system is low;

[0005] 2) On-line monitoring of the health status of medium-voltage switchgear cannot be realized, the degree of visualization is poor, potential defects that may exist in the equipment cannot be found, and the defects can be eliminated in time, and the safe and reliable operation of equipment and systems cannot be ensured, and the risk of unexpected power outages can be reduced;

[0006] 3) There is no arc extinguishing device that can respond in time, which cannot effectively shorten the arc duration and reduce the damage to equipment caused by extreme faults, and the safety and stability of the system is poor.
