基于PI实时数据库的变电站无线测温系统的设计及应用

Design and Application of Wireless Temperature Measurement System for Substations Based on Real-time PI Database

针对变电站设备传统测温方式精度低、实时性差、工作量大、成本高和无法自动连续监测的缺点,利用无线传输技术和PI实时数据库,建立变电站无线测温在线采集和实时监测系统,实现变电站设备温度管理及发热趋势分析,为状态检修提供决策。

Aiming at disadvantages of traditional temperature measurement method for substation equipment such as poor accuracy, real time inferiority, heavy workload, high cost and disability in automatic continuous monitoring, the wireless temperature measurement system is built for online collection and real-time monitor- ing by using wireless transfer technology and real-time PI database to enable management of substation equip- ment temperature and heating trend analysis to provide decision-making for condition-based maintenance. Key words： substation; real-time PI database; wireless temperature measurement; real-time monitoring; condition-based maintenance
