Online monitoring method of operation of transformer

Abstract

The invention discloses an online monitoring method of the operation of a transformer, and belongs to the field of GIS transformer station intelligent monitoring. The method comprises the step: setting an environment monitoring system, a state detection system and a comprehensive analysis monitoring platform, and is characterized in that the comprehensive analysis monitoring platform is also connected with a motion detection system and an early warning system; the environment monitoring system detects the environment parameters of a transformer station, and the state detection system detects the state of electric appliances of the transformer station; the motion detection system detects the operation, sound and transient electromagnetic changes of a GIS disconnecting switch, and uploads the data to the comprehensive analysis monitoring platform; the comprehensive analysis monitoring platform carries out the storage, comparison, analysis and outputting of the data, and carries out the early warning. The method achieves the centralized monitoring maintenance and management of the transformer station, and improves the reliability of the system and the safety of equipment. Through the monitoring of the operation state of the GIS disconnecting switch, the method achieves the early warning against a fault, achieves the advanced warning against the fault, selects a standby guarantee, and improves the power supply quality.

Description

technical field [0001] The invention relates to the field of GIS substation intelligent monitoring, in particular to an online monitoring method for substation operation. Background technique [0002] With the rapid development of computer technology and network communication technology, the development of power system automation construction has become more and more perfect. Monitoring system, intrusion alarm system, SF6 gas detection system and fire protection system, etc. [0003] The traditional substation security intelligent system is affected by traditional concepts and technologies. Each subsystem is isolated and cannot realize the linkage of the system. Not only the system relies on human monitoring, which leads to low security, but also increases the burden on the center management personnel and Work pressure, and greatly increased the investment of the power supply company, so that there is a monitoring "island" phenomenon, which virtually reduces the practicabil...

Problems solved by technology

[0003]The traditional substation security intelligent system is affected by traditional concepts and technologies. Each subsystem is isolated and cannot realize the linkage of the system. It leads to lower security, and increases the burden and work pressure of the center management personnel, and greatly increases the investment of the power supply company, so that a monitoring "island" phenomenon appears, which virtually reduces the practicability and stability of the system and security, but also increased investment costs

[0004] Chinese patent application CN201510771288.7 discloses a distribution substation operation status monitoring and safety early warning device, which solves the technical problems that the real-time monitoring of substations is not in place and the early warning is not timely

Its shortcoming is that it does not detect the transient state and provide early warning before the fault occurs
