Substation monitoring system

Abstract

The invention relates to a substation monitoring system, which comprises a first zone and a second zone; the first zone and the second zone are connected through a data bus, and the data bus is provided with a firewall located between the first zone and the second zone; the first zone comprises a relay protection device, a measuring and control device, an alternating current/direct current monitoring system, an integration monitoring platform and a telecontrol machine; the relay protection device, the measuring and control device, the alternating current/direct current monitoring system, the integration monitoring platform and the telecontrol machine are respectively and electrically connected with the data bus located in the first zone; the second zone comprises an online monitoring module and a comprehensive processing unit; the online monitoring module and the comprehensive processing unit are respectively and electrically connected with the data bus located in the second zone. The substation monitoring system disclosed by the invention has the advantages that the safety performance is higher, reasonable integration of equipment in a substation is realized, management is convenient, the structure is simple, and the economic efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a substation monitoring system. Background technique [0002] The operation monitoring of the station control layer in the existing substation, the billing of five preventions, the transmission of protection information, and the transmission of telecontrol information are all processed through different hosts or workstations, and the substation also has online monitoring equipment for main transformers and GIS / circuit breakers. , surge arrester online monitoring equipment, and power quality monitoring equipment, through its monitoring system data, and send the data to the master station respectively with a single channel. In this way, existing substations cannot meet the needs of substation data sharing and comprehensive information processing, which separates various businesses. The control and operation equipment adopts 2 redundant workstations, 1 set of dual-mac...

AI Technical Summary

Problems solved by technology

In this way, the existing substation cannot meet the needs of substation data sharing and comprehensive information processing, which separates various businesses

The control and operation equipment adopts 2 redundant workstations, 1 set of dual-machine redundant workstations, 1 set of dual-machine redundant workstations for telecontrol, independent workstations for five defenses, and online monitoring data cannot be obtained

Secondly, due to the large number of independent systems, which are configured according to functions, the hardware configuration is complicated and the economy is poor

Thirdly, due to the lack of data sharing mechanism and comprehensive information processing function, it is difficult to build a panoramic data platform for substations, and functions such as substation status maintenance, equipment detection, and program control cannot be realized.
