Highway Substation Power Monitoring System Of Real-time Database Research And Design

The electric power monitoring system which processes each kind of accident and alarm event, realizes movement of the electricity system, the device of each kind of substation and OCS for the all-time Urban Mass Transir are also remote real-time controlled, monitored and measurement by the electric power monitoring system. Real-time database is a core which the entire electric power monitoring system processes, nearly any system function all is truthfully when database entrance, also is revolving the real-time database this core realization. Data is the application functions foundation of the electric power monitoring system. It is very important to design a good performance and reliable real-time database.This paper unifies the characteristic of the electric power monitoring system for UMT, has analyzed each main module's functionin the real-time database system, has designed a distributed large-scale real-time database system based on the COM technology. Among them, considered real-time data working life, has proposed the improvement based on two-phase locking. In the aspect of data storage, proposed the real-time data placement strategy and the data physics orgnization way. The object-oriented data modeling technology is used to construct the electric power monitoring system real-time database data model.After researched the technology of Real-Time Database, under the C# development environment, constructs the WEB application using the Microsoft's newest.NET frame, the author has realized a single plane version real-time database based on the memory, has compiled the real-time database engine, the database interface and the data object defines three levels the functions. In the Qing Lian expressway Power Monitoring project the data model was running tests. Through several months of operation, the entire database system notonly meets the requirements of the various functions of the system, and for some months to run properly.
