摘 要：水电站计算机监控系统利用自动控制、计算机技术实现整个电站的自动化监测和控制目标，提高电站控制的安全性、可靠性，实现工程管理的科学化、现代化，充分发挥枢纽工程经济效益和-效益。本文通过对于丹竹水电站现地控制单元的研究，确保系统的经济实用、安全可靠、技术先进、易于维护，提升自动化、信息化水平。
关键词：现地控制单元；顺序控制；准同期
1 前言
广东省梅县丹竹水电站位于梅州市境内，是梅江干流中的一个梯级。电站内装设4台灯泡贯流式水轮发电机组。单机容量为8500KW，发电机额定电压6.3KV，额定功率因素0.9，电站采用扩大单元（两机一变）接线方案。电站共装设2台主变压器，高压侧电压为110KV，两回110KV线路接入梅州110KV电网。该电站机组已经投产发电。配置五套LCU，分别为机组LCU1, 机组LCU2, 机组LCU3, 机组LCU4,和公用/厂用电/开关站LCU。所有LCU均以GE90-30PLC 为核心进行实时数据采集和处理，顺序控制，和提供（机组）有/无功调节，事故追忆和提供现地人机界面等功能。在PLC梯形逻辑编写和调试过程中，充分考虑了软件的可移植性和通用性，软件按功能划分，既为一个整体又相互独立。
系统接受梯调的调度指令，实现AGC、AVC、厂内经济运行、自动监测和闭环控制，提高电厂运行经济效益，提高电厂安全运行水平，改善职工运行条件及提高电能生产的质量。现地级监控层LCU直接控制和监视主设备的运行，在整个系统中，它作为一个智能终端，但也可以作为独立的装置单独运行。
