水电厂计算机监控系统上位机改造新老系统网络割接的实践

Practice of Network Cutover Between Old and New Systems in the Upper Comput-er Transformation of Computer Monitoring System in Hydropower Plants

某水电厂计算机监控系统上位机原使用北京中水科技有限公司的H9000系统,因投运年限较长,改造为国电南京自动化股份有限公司的Herc8000系统。阐述了计算机监控系统下位机系统网络通信逐步转移至新上位机系统的具体实践方法,实现水电厂计算机监控系统上位机与下位机、调度通信的平稳过渡,提高水电厂的安全稳定运行。该实践对同一类型改造项目的实施提供了较好的借鉴意义。

The upper computer of the computer monitoring system in a hydropower plant originally used the H9000 sys‐tem of Beijing Zhongshui Technology Co.,Ltd.Due to its long service life,it was transformed into herc8000 system of Guodian Nanjing Automation Co.,Ltd.This paper expounds the practical method of gradually transferring the network communication of the lower computer system of the computer monitoring system to the new upper computer system.Realize the smooth transition between the upper computer and the lower computer of the computer monitoring system of the hydropower plant and the dispatching communication,and improve the safe and stable operation of the hydropow‐er plant.This practice provides a good reference for the implementation of the same type of reconstruction project.
