抽水蓄能电站监控系统国产化改造方案研究

Research of the Domestic Modification Schemes for the Computer Supervision and Control Systems of Pumped Storage Power Stations

20世纪80年代以来我国大中型抽水蓄能电站选用的国外计算机监控系统面临着设备老化、系统功能不足、备品备件及售后服务质量差等现状。简述了国内抽水蓄能电站计算机监控系统技术进展状况,分析研究了国外抽蓄电站计算机监控系统国产化改造方案。文中首先分析了常规水电站计算机监控系统升级改造的三种常见方法,并进一步分析了我国抽水蓄能电站计算机监控系统升级改造的典型案例,总结提炼出可行的两种改造方式:增设中间转换设备、不增设中间转换设备。文中分析了张河湾抽水蓄能电站、广蓄B厂抽水蓄能电站、广蓄A厂抽水蓄能电站监控系统采用增设中间转换设备升级改造应用案例的特点,分析了河南宝泉、湖北白莲河、广东惠州等抽水蓄能电站的监控系统采用工控机作为LCU主机以非标准通信协议的升级改造中遇到的难题,结合河南宝泉抽水蓄能电站监控系统国产化升级改造项目研究,重点研究分析了采用不增加中间转换设备实现非公开协议电站监控系统升级改造方案的实现。

The computer supervision and control systems(CSCS)for the pumped storage power stations supplied by suppliers abroad,face problems such as equipment aging,insufficient system functions,spare parts,after-sale service,etc.This paper introduces the current technology status of the domestic pumped storage power station CSCS,describing and researching domestic modification schemes for CSCS of Pumped Storage Power Station.The paper analyses three ways of domestic modification for hydropower plants CSCS,then discusses those ways of domestic modification for pumped storage power station CSCS,summarizing two models:with middle transformation instruments added and with nothing added.The characteristics of those typical cases with middle transformation instruments added are discussed which are Zhanghewan Pumped Storage Power Station,Guangzhou B Pumped Storage Power Station,Guangzhou A Pumped Storage Power Station.This paper researches those problems in modification schemes for those cases which the LCU main computer is IPC with nonstandard communication protocol in it,Henan Baoquan Pumped Storage Power Station,Hubei Bailianhe Pumped Storage Power Station,Guangzhou Huizhou Pumped Storage Power Station.Based on the project of domestic modification for computer supervision and control system of Baoquan Pumped Storage Hydropower Station,studies its domestic modification schemes for computer supervision and control systems without any transformation instrument.
