Design Of Distribution Network Circuit Breaker On-line Supervision Based On Application Of GIS-Communication

With the expansion of the scale of modern power, the power system to high-capacity, high-voltage direction, the main equipment for power system operation status and alarm information and other real-time information on the remote, real-time monitoring the safe operation of the industry necessary prerequisite. The many advantages of GIS network makes an unparalleled advantage of remote monitoring system based on GIS. The substation design of real-time monitoring system monitoring and management to meet the modern flexible monitoring, rapid deployment requirements, set computer, automatic control, electrical, communications and other technologies in one, using GIS technology, wireless communication system, according to the monitoring collection point spread, the characteristics of low real-time requirements, achieve unattended monitoring site, the monitoring center centralized monitoring, centralized maintenance to solve modern wireless communication systems centralized management of an unparalleled advantage.This project studies the design of GIS-based remote monitoring of substation terminal, terminal to send and receive Chinese text messages in accordance with the requirements of the design by the substation SCADA system running on data collection, through the preparation of SMS AT commands control the TC35 module use the form of SMS text messages to complete Substation data transmission, to achieve the purpose of remote monitoring.The main contents of this project: first, Introduced SCADA supervisory control and data acquisition system, GIS networks, SMS messaging system, the definition, characteristics, structure, function and application of. Second, account for the application of the monitor terminal, as TC35 terminal and other hardware, including the main parameters of the various parts, hardware features, such as connection. Third, through the send and receive examples,introduction and current mobile phones generic PDU encoding; TC35 modules listed common AT control command, description the implementation of using AT commands to send and receive SMS and complete software. Fourth, through Hyper Terminal software, completed the verification of message debugging.
