Mid and low-voltage distribution network intelligent monitoring system based on 3G communication network

Abstract

The invention discloses a mid and low-voltage distribution network intelligent monitoring system based on a 3G communication network, which comprises a remote monitoring main station, a monitoring substation and a communication system, wherein the remote monitoring main station is in the highest layer of the entire system and is in charge of graphic display, background processing, report output, remote power device control and interaction completion between an upper computer and the bottom monitoring substation; the monitoring substation is an execution layer of the entire system and is in charge of uploading various states of a field device, receiving various instructions issued by the upper computer and instructing a field intelligent terminal to complete a required command; and the communication system is used for remotely monitoring interaction of data between the monitoring main station and the monitoring substation. Through recording and analyzing the operation state of the power device in real time, the working state and the service life of the power device are reasonably judged for later reading and check. Based on the 3G communication network, the system of the invention realizes functions of telemetering, remote communication, remote control, remote vision, device health state detection, environmental detection, preliminary electricity analysis and the like.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to an intelligent monitoring system for a medium and low voltage distribution network based on a 3G communication network. Background technique [0002] The construction of communication system is one of the key and difficult points in realizing distribution network automation. The cables, power line carriers, waveguides, optical cables, etc. used in the traditional power remote monitoring system have many disadvantages, which are neither economical nor convenient. In recent years, with the rapid development of public mobile communication technology and its communication network, the price and operating cost of communication equipment are getting lower and lower, and the information integrated business service function is becoming more and more powerful. The communication quality of digital cellular networks such as GPRS / 3G is high, and there are few blind spots in its covera...
