基于 PI 数据库的风电场实时监控系统应用研究

摘要

This paper introduces in depth the composition and characters of the PI (Plant Information)database system (PI system server end, PI client-end software)as well as the difference between it and relational database.With respect to the characteristics of the PI system,this paper presents a scheme of unique encoding of measuring point.On that base,it expounds a deployment scheme for remote centralized monitoring system for wind farm based on PI database,as well as specific implementation of key technologies in the system construction such as data acquisition,exchange and storage,fan control,substation control,data calculation,delivery and display.That can be used for reference in the construction of the remote monitoring system of wind farms.%介绍了PI（Plant Information System）数据库系统构成（PI系统服务器端、PI客户端软件）和系统特点，以及与关系数据库的区别，针对PI系统特点，提出了测点编码唯一性方案。详细阐述了一种基于PI数据库的风电场远程集中监控系统部署方案，以及在系统建设中的数据采集、交换与存储、风机控制、变电站控制、数据计算、外送和展示等关键技术的具体实现，对风电场远程监控系统建设有一定的借鉴作用。
