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。
