摘 要：水電站計(jì)算機(jī)監(jiān)控系統(tǒng)利用自動(dòng)控制、計(jì)算機(jī)技術(shù)實(shí)現(xiàn)整個(gè)電站的自動(dòng)化監(jiān)測(cè)和控制目標(biāo)，提高電站控制的安全性、可靠性，實(shí)現(xiàn)工程管理的科學(xué)化、現(xiàn)代化，充分發(fā)揮樞紐工程經(jīng)濟(jì)效益和-效益。本文通過(guò)對(duì)于丹竹水電站現(xiàn)地控制單元的研究，確保系統(tǒng)的經(jīng)濟(jì)實(shí)用、安全可靠、技術(shù)先進(jìn)、易于維護(hù)，提升自動(dòng)化、信息化水平。
關(guān)鍵詞：現(xiàn)地控制單元；順序控制；準(zhǔn)同期
1 前言
廣東省梅縣丹竹水電站位于梅州市境內(nèi)，是梅江干流中的一個(gè)梯級(jí)。電站內(nèi)裝設(shè)4臺(tái)燈泡貫流式水輪發(fā)電機(jī)組。單機(jī)容量為8500KW，發(fā)電機(jī)額定電壓6.3KV，額定功率因素0.9，電站采用擴(kuò)大單元（兩機(jī)一變）接線方案。電站共裝設(shè)2臺(tái)主變壓器，高壓側(cè)電壓為110KV，兩回110KV線路接入梅州110KV電網(wǎng)。該電站機(jī)組已經(jīng)投產(chǎn)發(fā)電。配置五套LCU，分別為機(jī)組LCU1, 機(jī)組LCU2, 機(jī)組LCU3, 機(jī)組LCU4,和公用/廠用電/開關(guān)站LCU。所有LCU均以GE90-30PLC 為核心進(jìn)行實(shí)時(shí)數(shù)據(jù)采集和處理，順序控制，和提供（機(jī)組）有/無(wú)功調(diào)節(jié)，事故追憶和提供現(xiàn)地人機(jī)界面等功能。在PLC梯形邏輯編寫和調(diào)試過(guò)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(gè)整體又相互獨(dú)立。
系統(tǒng)接受梯調(diào)的調(diào)度指令，實(shí)現(xiàn)AGC、AVC、廠內(nèi)經(jīng)濟(jì)運(yùn)行、自動(dòng)監(jiān)測(cè)和閉環(huán)控制，提高電廠運(yùn)行經(jīng)濟(jì)效益，提高電廠安全運(yùn)行水平，改善職工運(yùn)行條件及提高電能生產(chǎn)的質(zhì)量?，F(xiàn)地級(jí)監(jiān)控層LCU直接控制和監(jiān)視主設(shè)備的運(yùn)行，在整個(gè)系統(tǒng)中，它作為一個(gè)智能終端，但也可以作為獨(dú)立的裝置單獨(dú)運(yùn)行。
