Research On Intelligent Surveillance&Monitoring System For Substation Based On Ethernet

Substation is an important link of transmission and distribution system, is a majormonitory point of grid. In recent years, in order to improve the quality of power supply,ensuring safe, reliable and economic operation of the power system, the construction ofintelligent substation become more and more important. Considering some question thatinformation island, real-time and reliability of transmission network is not high in the processof intelligent substation construction, study and designed a substation intelligent surveillance&monitoring system based on Ethernet, there is a great significance in intelligentmanagement of substation equipment and internal environment.The research background of his article is the smart grid power construction andexperimental study on the project of Local Power (Group) Company in Shaanxi Province,introduces production status of Shunning substation in ZhiDan Xian, establish the monitoringof transformer substation monitoring requirements. From the station system, communicationsystem, and master station system, design the monitoring hardware composition of themonitoring system, which focuses on Ethernet communication system based on SynchronousDigital Hierarchy (SDH), this communication system can provide the ideal networkperformance and system reliability; Finally, develop primarily with video monitoring,environment monitoring and auxiliary concentrated intelligent surveillance monitor interface,realize the video and the environmental monitoring data (such as temperature and humidity,SF6gas, water, fire, alarm equipment) of real-time data acquisition, centralized monitoring,storage, and management.The system of the actual application shows that the system resolve problem aboutinformation island and the reliability of system, real-time performance about data transmission,realize the dynamic station real time video display, dynamic parameters of remote real-timemonitoring and equipment start-stop, The surveillance monitoring system has certain referencesignificance and promotion value.
