Design And Implementation Of Intelligent Substation Auxiliary Management System

The power system covers the power generation,transmission,power transformation,distribution,electricity consumption and other segment and factors.As the basis of the power system and power network,the role of the substation is mainly reflected in the transformation of voltage level,the collection of current,the distribution of electric energy and adjust the voltage and so on.Substation equipment,business processes and environmental monitoring,maintenance and other functions have important effect on substation itself and the normal operation of power grid and power system.Because of the geographical distribution of many substation and each substation internal complex electromagnetic environment,more kinds of equipment and other factors,the monitoring and maintenance work is more complicated.Therefore,its need to apply comprehensive approach,including information technology to solve practical engineering requirements.In this paper,the intelligent substation auxiliary system in two kinds of typical functional modules,namely environmental monitoring equipment and fire equipment maintenance,is considered as the specific research object,through the comprehensive use of software engineering technology and networking technology,implement the operation condition of the main electrical equipment and auxiliary equipment,the work environment monitoring,maintenance and security information system.The equipment room environment monitoring function module adopts the technology of the embedded controller,ZigBee communication and network to realize the information collection and transmission;fire equipment maintenance module adopts B/S architecture,UML(Unified Modeling Language)and Java framework,to achieve the server and client software design.The results of this study can collect monitoring,such as environmental temperature and humidity,video and fire protection(online and offline device status),heating,ventilation,lighting,SF6,security protection,entrance guard and so on,using the technology of the Internet of things,by wireless sensor network of ZigBee are uploaded to the server,fire equipment and maintenance functions can be implemented through mobile phone app function monitoring and maintenance of the equipment.The management of intelligent substation has improved the efficiency and intelligence.The practical application shows that the system can satisfy the online monitoring of the substation equipment and environment parameters,and the inspection function of the fire fighting equipment,and has achieved good social and economic benefits.
