高砂水电厂选用了中国水利水电科学研究院自动化所的 H 9000水电站计算机监控系统,是一种全分层分布开放式总线型计算机控制系统,采用快速以太网和交换以太网相结合的网络配置,系统主机采用 Compaq 公司的 Alpha XP1000工作站和 DEC 公司Digital UNIX V4.0实时操作系统,下位机采用性价比较优的 GE90-30可编程序控制器,PLC 直接上以太网。此系统的成功应用,为高砂水电厂“无人值班”(少人值守)及创“一流水电厂”奠定了坚实的基础。
Gao Shashui hydropower plant selected by the China Institute of Water Resources and Hydropower Automation H 9000 hydropower station computer monitoring system is a full hierarchical distributed open bus computer control system using Fast Ethernet and switched Ethernet network configuration combination, System host using Compaq’s Alpha XP1000 workstation and DEC’s Digital UNIX V4.0 real-time operating system, the next crew using cost-effective GE90-30 programmable logic controller, PLC directly on the Ethernet. The successful application of this system has laid a solid foundation for the high sand power plant “unmanned ” (less manned) and record “first-class water power plant ”.
