隨著國民經(jīng)濟(jì)的發(fā)展和人民生活質(zhì)量的提高,電力對國民經(jīng)濟(jì)的重要性和人民生活質(zhì)量的提高之間的關(guān)系越來越緊密。由于電力生產(chǎn)的特殊性,在“抓安全,重效益”的企業(yè)目標(biāo)下,提高電力可靠性變成了一項(xiàng)社會性的工作。只有充分發(fā)揮各級管理人員的積極性和創(chuàng)造力,依靠技術(shù)的進(jìn)步,有效調(diào)動全體員工的能動性,才能把提高發(fā)電設(shè)備可靠性這項(xiàng)工作做得更細(xì)、更實(shí),以取得良好的績效。
對于大型電廠,控制系統(tǒng)的可靠性對整個電廠的安全可靠性生死攸關(guān)。上世紀(jì)七十年代左右,隨著4C技術(shù)的發(fā)展和火電廠單機(jī)參數(shù)的提高,控制系統(tǒng)向功能分散、管理集中方向發(fā)展,其可靠性也得到了大大的提高,國外開始在大型電廠(站)中開始采用分散控制系統(tǒng)(DCS)。我國也于上世紀(jì)八十年代中后期在成套引進(jìn)發(fā)電機(jī)組上應(yīng)用DCS,至目前,新建機(jī)組在控制系統(tǒng)選型上均采用了各型成熟的DCS控制系統(tǒng),單機(jī)容量較大的老機(jī)組也通過控制系統(tǒng)改造,基本采用了DCS控制系統(tǒng)。
作為技術(shù)進(jìn)步的體現(xiàn),DCS控制系統(tǒng)的大范圍推廣,為電力生產(chǎn)的安全、經(jīng)濟(jì)運(yùn)行作出了巨大貢獻(xiàn)。但在國家電力體制改革后,尤其是市場經(jīng)濟(jì)的調(diào)控下,如何盡可能提高DCS控制系統(tǒng)的可靠性,從而保證電力生產(chǎn)的安全和經(jīng)濟(jì),以盡可能提高安全和利潤指標(biāo)變成了一項(xiàng)越來越重要的工作。
