Residential Substation Running Environment Monitoring And Comprehensive Analysis System

Residential substation is the key of connecting distribution network and power users. Its reliability is directly related to the safety and stability of distribution network. Research found that the operating environment of residential substations is complex and has lots of security risks. With the community's growing demand of power supply reliability, improving the residential substations'automation and information level, and ensuring their reliability, have become an inevitable way.This paper analyzes the demand of residential substation running reliability, summarizes various parameters of the running environment, and selects the monitoring sensors. By learning from the monitoring systems in other areas, the monitoring system design for residential substation running environment is proposed. The program consists of station monitoring, background monitoring and system communication of three parts. Station monitoring is in residential substation, consists of intelligent collection and a variety of sensors, completes the function of running environment information collection and basic analysis; background monitoring is in the monitoring center, consists of monitoring server and database server, completes statistical analysis and storage capabilities of the information; system communication uses wireless communication through the existing public wireless communication network, to achieve data exchange between background monitoring and station monitoring.Finally, through statistical analysis of collected data, the running environment of residential substation is objectively and comprehensively reflected. It greatly improves the automation level of distribution network running environment monitoring.With follow-up research work carried out, the basis of residential substation running environment monitoring will provide strong technical support for distribution network reliable running.
