介绍了蒲石河抽水蓄能电站计算机监控系统现地控制单元(LCU)回路的电源、网络结构、同期回路、水机回路等设计。此设计满足了蒲石河抽水蓄能电站对电站安全、高效的生产要求,为抽水蓄能电站监控系统国产化奠定了坚实的基础,同时为国内大型抽水蓄能电站监控系统的设计提供参考。 This paper introduces the design of power supply, network structure, synchronous circuit and water circuit of the local control unit (LCU) of the computer monitoring system of Pushihe Pumped Storage Power Station. The design meets the requirements for the safe and efficient production of the Pushihe Pumped Storage Power Station and provides a solid foundation for the localization of the pumped storage power station monitoring system. Meanwhile, it provides a reference for the design of the monitoring system for the domestic Pumped Storage Power Station.
