介绍基于PI数据库的断面潮流在线监测及告警系统的实现方案和关键技术。应用SVG的可视化技术实现潮流监测图的动态显示,通过C/S客户端实现了潮流越限告警功能。该系统为集控站的安全运行提供了有效的监测和分析方法,并且对有效利用PI实时数据库开展电力业务的高级应用提供了借鉴。
This paper introduces the implementation plan and key technologies of on-line power flow monitoring and alarm system based on PI database. The visualization technology of SVG is used to realize the dynamic display of power flow monitoring map. The trend current limit alarm function is realized by C / S client. The system provides an effective monitoring and analysis method for the safe operation of the centralized control station, and provides reference for the advanced utilization of the power service by effectively utilizing the PI real-time database.
