| Along with the development of national economy, electric power system scale more and morehuge, structure is also becoming more and more complicated. Power system once themalfunction, will be to national security and the people’s production and life have a significantimpact. Therefore, how to guarantee the safety of the power system, and reliably appear evenmore urgent.Relay protection is the power system protection, control, operation scheduling and accidenttreatment of integrated automation system important constituent. It to guarantee the safety ofthe power system plays a very important role. Relay protection and fault information system ismainly in the electric power system malfunction, will power grid failure and secondary equipmentinformation collection and rapid action uploaded to the master station, and the master station torealize the intelligent fault information analysis and processing, thus greatly improve the systemfault especially complex system fault analysis and processing capacity.This paper has a deep analysis of daqing lianhua company existing grid conditions, and basedon the international standard design of open system, based on the new structure and new device,the new processing technology, high standard electromagnetic compatibility design for the highreliability of the hardware platform and daqing lianhua110kv a change completed and moredistribution station secondary equipment upgrades and access,forcing the dispatching systemvoltage level rise and monitoring data volume increase, and the current electric powerdispatching system is limited to distribution station data acquisition and monitoring, the moreimportant thing is through the dispatching system to realize the reasonable distribution of thepower resources, the energy management, operation rehearsal, accident anticipation andaccident analysis application function, rise to control the overall situation, grasp the overallsituation of the decisive role. And daqing lianhua company now application PRS700J set controlstation system already can not adapt to the development of big scheduling needs, the need toupgrade for NS2000power dispatch automation system, and meet the international standarddesign to realize embedded real-time multitasking operating system VxWORKS software platform,support total data sharing, does not depend on station control layer to realize total controloperation logic atresia, make the software reliability and real time greatly enhanced so as to meetthe demand of the network of daqing refining. So the upgrade power dispatch automation systemtechnology and the key theory and design scheme for the popularization and application of thescheduling system is of great significance. |
