姚河坝水电站计算机监控系统原来采用的是ALSTOM电力系统公司生产的Alspa 8000-P320型计算机监控系统,现地控制单元采用的是以GE9030 PLC为基础的Alspa P320现地控制装置。改造后上位机软件采用的是南瑞自动控制公司生产的NC2000型计算机监控系统软件,下位机采用的是南瑞自动控制公司拥有自主知识产权的MB80智能可编程控制器为主的SJ-600监控系统。文中主要介绍了姚河坝水电站计算机监控系统改造前后监控系统的特点、配置、功能。
Yaoheba Hydropower Station computer monitoring system originally used by ALSTOM power system company produced Alspa 8000-P320-type computer monitoring system, the local control unit is based on GE9030 PLC-based Alspa P320 is a local control device. After the transformation of PC software is NARI automatic production company NC2000 type computer monitoring system software, the next crew using the NARI automatic control company has independent intellectual property rights MB80 intelligent programmable logic controller based SJ-600 monitoring system. This paper mainly introduces the characteristics, configuration and functions of the monitoring system before and after the computer supervisory system of Yaoheba Hydropower Station.
