Remote monitoring system design of power substation based on GPRS

Abstract

This paper studies the design scheme of a substation remote monitoring system based on GPRS, and gives the solution about poor real-time and imperfect function of centralized substation monitoring system. The working principle diagram of the measurement and control device is introduced in detail, and the modules of analog acquisition and switching input are designed. The substation remote monitoring software based on GPRS communication is developed to realize the remote real-time monitoring of electrical and switching parameters and other functions, such as data query, fault early warning and energy efficiency analysis. The experimental results show that the system has the characteristics of real-time, multi-function and high reliability. It is of great significance to implement defensive maintenance, improve power supply quality, save energy and reduce consumption.
