特高压输变电设备状态监测数据通信仿真研究

针对特高压输变电设备状态监测系统主站转发数据时效性低、负荷重的问题,提出从特高压变电站直接获取输变电设备状态监测数据的获取方式,并利用OPNET建立仿真模型,对比了转发方式与直采方式下,输变电设备状态监测系统主站数据中心服务器与特高压端数据服务器系统负载、CPU使用率、业务处理时间的异同。结果表明,通过直采方式获取特高压变电站设备状态监测数据效率较高,对服务器影响较小。

Simulation Research on UHV Equipment Condition Monitoring Data Communication

In order to solve problems of data latency and high database server load of master station in UHV equipment condition monitoring system, a new data acquisition approach is proposed. Proposed approach extracts data directly from database server deployed in the substation instead of forwarding data from data center which deployed in control center. By using OPNET modeling method, two approaches are compared in terms of system load, CPU utilization and business processing time. Results show that proposed method is more efficient, and has less impact on the server.
