Transformer substation telemetry information test system

Abstract

The invention discloses a transformer substation telemetry information test system comprising a remote signaling module, a time synchronization module, an I / O data processing module, a communication module, a central processor, a database, a telemetry module, a monitoring system and a PLC control unit. The remote signaling module comprises a transformer substation implementation simulator and a hardware information acquisition module. The remote signaling module and the time synchronization module are connected through synchronization signals. The remote signaling module and the I / O data processing module are connected through electric signals. The I / O data processing module and the communication module are connected in a signaling way. The communication module and the central processor are connected in a signaling way. The central processor and the database are connected through the electric signals. The database and the monitoring system are connected through the electric signals. The monitoring system and the telemetry module are electrically connected. The telemetry module and the PLC control unit are electrically connected through a wired communication module. The PLC controlunit and the telemetry module are connected through cable electric signals.

Description

technical field [0001] The invention belongs to the technical field of electric power testing systems, and more specifically relates to a substation remote measurement information testing system. Background technique [0002] With the rapid development of the power system, the integrated automation systems of substations and power plants have been put into use in large quantities. When using the integrated technical support system for prefectural and county regulation, many domestic users are usually not satisfied with the frequent and jittering remote signaling information of the system. The processing method, especially the energy storage information of the capacitor spring, AVC (automatic voltage and reactive power control system) will be accompanied by a large amount of such information when switching / cutting capacitors in a large area. In the traditional way, it is generally carried out manually or semi-automatically. The efficiency is low. Due to the influence of human...

[0002] With the rapid development of the power system, the integrated automation systems of substations and power plants have been put into use in large quantities. When using the integrated technical support system for prefectural and county regulation, many domestic users are usually not satisfied with the frequent and jittering remote signaling information of the system. The processing method, especially the energy storage information of the capacitor spring, AVC (automatic voltage and reactive power control system) will be accompanied by a large amount of such information when switching / cutting capacitors in a large area. In the traditional way, it is generally carried out manually or semi-automatically. Low efficiency, due to the influence of human factors, the reliability of test results is not high, which seriously affects the normal scheduling and monitoring of controllers, poor use effect, low work efficiency, and poor practical performance
