输变电设备集中监控大数据研究及应用

随着智能电网的快速发展和调控一体化运行体系的深入推进,接入调控中心的输变电设备集中监控信息数据成倍增长,如何从海量的监控信息数据中挖掘出需要的信息,直接指导监控员的工作,由被动监控转为主动监控,显得尤为迫切。国网浙江省电力有限公司针对现状率先开展了输变电设备集中监控信息大数据技术的研究与应用,基于智能电网调控技术支持系统搭建了一个由各类监控信息分析模块组成的信息分析中心,通过对输变电设备告警信息进行挖掘分析实现集中监控信息的优化整合和分类处置,可以显著提升监控员的日常工作效率。文章首先概述了输变电设备集中监控信息分析中心的总体结构,然后介绍了其采用的优化算法,最后结合浙江电网的实际运行情况,对各类监控信息分析模块进行了具体应用,其分析结果可为监控员提供相应的辅助决策,为浙江电网的安全运行提供保障。

The big Data Research and Application of the Electric Transmission and Transformation Equipment Centralized Monitoring

With the rapid development of the smart grid and further promotion of the control integration operating system, the centralized monitoring information data of electric transmission and transformation equipment connected to the control center has presented the exponential growth. It becomes extremely urgent to dig for information needed from the massive monitoring information data, guide the work of monitors directly and turn the passive monitoring to be active monitoring. State Grid Zhejiang Electric Power Corporation takes the lead in launching the researches and application of the big data of centralized monitoring information of the electric transmission and transformation equipment by aiming at the current status, and establishes an information analysis center comprised by all kinds of monitoring information analysis modules based on the smart grid control technology support system, which will implement the optimized integration and sorted processing of centralized monitoring information by conducting the big data mining analysis through the warning messages of electric transmission and transformation equipment, and improve the daily work efficiency of monitors significantly. In the paper, the overall structure of the centralized monitoring information analytic center of the electric transmission and transformation equipment are introduced generally first. Then the optimization algorithm which is adopted by the system is introduced. Finally, combining the actual operation conditions of Zhejiang power grid, the specific application of various monitoring information analytic modules are implemented, and the analysis result will not only provide corresponding aided decision for the monitors, but also ensure the safe operation of Zhejiang power grid.
