Development And Application Of Substation Auxiliary Equipment Monitoring System

The power industry is related to the pillar industry of the national economy and the people’s livelihood, and substation is the most critical project, to ensure the substation auxiliary equipment and environmental safety is one of the priorities of the electric system. To build the minitor system of the converting station converging whole area is the indispensable step to guarantee electric system state overhaul and meticulous manage.At present auxiliary equipment of the substation automation monitoring are confined to the substation internal information sharing individual,can not be achieved between different modules,therefore it is difficult to deploy unified monitoring system for substation. With the improvement of the the substation auxiliary equipment and its supporting systems, developing a comprehensive, intelligent substation auxiliary equipment become a urgent problems to be solved.This paper designs a WEB-based substation auxiliary equipment monitoring system, firstly it focus on the inadequacies of existing monitoring system, desingn the overall function and architecture of the monitoring system; in the data acquisition modules, design the monitoring node hardware and communication processes of fire protection system and air-conditioning system using ZigBee wireless technology and BACnet standard; in data application services,researched the interface configuration module and communication protocol module based on the configuration monitoring software standard; for the problem of data storage,designed real-time historical database file structure.The main research content includes the following aspects:1.The overall architecture design of the substation auxiliary equipment monitoring system, including the hardware structure, the software module division and functional requirements.2.Implementation of data acquisition and protocol translation module,study how to use ZibBee wireless networking technology in fire fighting system, and given the hardware node design and communication processes; Research the application of BACnet standard in substation air conditioning monitoring system, design its networking mode and the WEB-based access method.3.with the monitoring configuration software standards, design each application service module of the monitoring system, and gives the detailed design ideas and implementation methods of interface configuration module and the communication protocol configuration module.4. According to the data access requirements, design the structure and module division of real-time monitoring system history database, and detailed discuss the data access process, archiving process analysis and query methods.In the development process of the monitoring system, we focus on standardization and modular design, conducive to further improvement and maintenance, facilitate of data integration with existing power monitoring system, and build the substation integrated automation system.
