摘　　要：介绍了重庆电网基于PI数据库的实时动态监测系统(WAMS)的总体结构、建设目标和基本功能。该系统采用的PI数据库平台具有独特的数据压缩技术,大大降低了存储所需的容量,提高了数据查询速度,解决了WAMS系统数据存储的技术难题,系统内采用的低频振荡监测算法具有计算快速、准确的特点,目前该系统已投入试运行。The overall structure, construction goal and basic functions of WAMS based on PI database in Chongqing Power Grid were introduced. This system adopted the PI database platform with unique data compressed technology, which reduced greatly the capacity for stocking, raised data inquiry speed, and solved the technical problems of data stocking for WAMS system.The monitoring algorithm of low frequency oscillation adopted in the system has the characteristics of calculating fast and accurately. Now, this system has put into trial operation.
