Operation station control system based on in-band out-band combination control mode for transformer station secondary equipment

Abstract

The invention belongs to the large-scale and old comprehensive automatic remote monitoring system field and particularly relates to an operation station control system based on an in-band out-band combination control mode for transformer station secondary equipment. The system comprises a digital KVM switch, an out-band management sub module, an in-band management sub module, a communication module, a substation comprehensive automatic server, an SVG browser, a data storage module, a network signal transmission module, a digital remote centralized management data acquisition module, a serial port module, a power management module, a frequency divider assembly and a substation to-be-acquired unit assembly, wherein the digital remote centralized management data acquisition module is connected with the substation to-be-acquired unit assembly through the frequency divider assembly, and the digital remote centralized management data acquisition module is connected with the substation comprehensive automatic server through the network signal transmission module. The system is advantaged in that operation and maintenance efficiency is high, multi-user concurrent remote browsing and multi-computer switching of the control center and an operation station can be realized, system fault detection usefulness is ideal, and resource configuration is flexible.

Description

technical field [0001] The invention belongs to the field of remote monitoring systems for large-scale operation of old comprehensive self-stations, and in particular relates to a management and control system for substation secondary equipment implemented by an operation and maintenance station based on an in-band and out-of-band combined control mode. Background technique [0002] Substation integrated automation system is to use advanced computer technology, modern electronic technology, communication technology and information processing technology to realize the control of substation secondary equipment (including relay protection, control, measurement, signal, fault recording, automatic device and telecontrol device). etc.) functions to recombine, optimize the design, and implement a comprehensive automation system that monitors, measures, controls and coordinates the operation of all equipment in the substation. Through the exchange of information and data sharing amo...
