摘 要：水電站計算機監控系統利用自動控制、計算機技術實現整個電站的自動化監測和控制目標，提高電站控制的安全性、可靠性，實現工程管理的科學化、現代化，充分發揮樞紐工程經濟效益和-效益。本文通過對于丹竹水電站現地控制單元的研究，確保系統的經濟實用、安全可靠、技術先進、易于維護，提升自動化、信息化水平。
關鍵詞：現地控制單元；順序控制；準同期
1 前言
廣東省梅縣丹竹水電站位于梅州市境內，是梅江干流中的一個梯級。電站內裝設4臺燈泡貫流式水輪發電機組。單機容量為8500KW，發電機額定電壓6.3KV，額定功率因素0.9，電站采用擴大單元（兩機一變）接線方案。電站共裝設2臺主變壓器，高壓側電壓為110KV，兩回110KV線路接入梅州110KV電網。該電站機組已經投產發電。配置五套LCU，分別為機組LCU1, 機組LCU2, 機組LCU3, 機組LCU4,和公用/廠用電/開關站LCU。所有LCU均以GE90-30PLC 為核心進行實時數據采集和處理，順序控制，和提供（機組）有/無功調節，事故追憶和提供現地人機界面等功能。在PLC梯形邏輯編寫和調試過程中，充分考慮了軟件的可移植性和通用性，軟件按功能劃分，既為一個整體又相互獨立。
系統接受梯調的調度指令，實現AGC、AVC、廠內經濟運行、自動監測和閉環控制，提高電廠運行經濟效益，提高電廠安全運行水平，改善職工運行條件及提高電能生產的質量。現地級監控層LCU直接控制和監視主設備的運行，在整個系統中，它作為一個智能終端，但也可以作為獨立的裝置單獨運行。
