Automatic transformer substation monitoring system with intelligent field bus error-correction function

Abstract

The invention provides an automatic transformer substation monitoring system with an intelligent field bus error-correction function. The automatic transformer substation monitoring system comprises an upper computer, a communication manager, an intelligent error correction device and an intelligent machine, wherein the upper computer, the communication manager and the intelligent error-correction device are sequentially connected; the intelligent error correction device is connected with the intelligent machine through a field bus. The automatic transformer substation monitoring system has the advantages and the positive effects that the downlink is connected in parallel to the same field bus, the uplink is connected with a central processing unit, equipment in the bus is monitored, data are identified and analyzed, and abnormal equipment in the bus is found in time and is positioned through an acoustic-optical signal; the intelligent error correction device has functions of isolation and error correction between the bus and each processing unit, and the stability of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring, and more specifically relates to an automatic monitoring system for a substation. Background technique [0002] With the wide application of communication equipment in substations, the frequency of data exchange between different devices is increasing, and more and more substations have higher and higher requirements for communication, and there are more and more types of field buses, but Due to the complexity of the site situation, the versatility of equipment from different manufacturers is relatively poor, resulting in the occurrence of communication failures in substations from time to time. It is particularly important to find problem components in the bus in time and improve the reliability of the field bus. [0003] Intelligent devices have been widely used in integrated automation substations. Information sharing has become the most basic requirement of the substation,...

AI Technical Summary

Problems solved by technology

In a substation, there are many smart devices from different manufacturers, and the communication quality of each smart unit is also different. Any abnormal communication of any device in the fieldbus will affect the communication quality of the entire system.
