变压器动态远程监测数据的存储和访问设计

The Visitation Design & Storage of Dynamic Long-range Monitoring Data of Transformers

利用从PMU获得的标有同步时标的数据分析变压器的实时运行状况,能够实时地对变压器进行动态远程监测。变压器的现场数据是对其进行监测的重要依据。监测过程中主要对变压器的电压、电流数据进行了动态监测,其实时数据量非常庞大。基于此,在经过试验比较后,数据存储的设计采用了数据存储量大、实时性好、安全性高的SQL Server 2000作为数据存储管理系统。设计了基于B/S(Brower/Serve)r的数据库访问模式,实现了变压器运行参数的远程监控。

It is possible to monitor the synchronous status of running status of transformer dynamically and remotely by using datum collected from PMU.The live datum is the most important for monitoring to transformer.The datum of current and voltage are monitored,which are of large storage capacity.According to the testing results,SQL Server 2000 is selected as the database management system because of greater storage abilities and better real-time properties.The modal of brower to server is designed in order to break the territory restriction and realize the long-range monitoring to the transformer.
