基于EJB技術(shù)的火電廠燃料配煤規(guī)劃系統(tǒng).pdf

1、華北電力大學(xué)碩士學(xué)位論文摘要在我國的火力發(fā)電企業(yè)中，燃料成本占整個發(fā)電企業(yè)發(fā)電成本的70%以上。因此，如何降低燃料成本合理配煤是火力發(fā)電企業(yè)提高經(jīng)濟效益的主要途徑。文章分析了目前電廠配煤規(guī)劃系統(tǒng)應(yīng)用現(xiàn)狀和存在問題，并對現(xiàn)有的配煤模型改進(jìn)，利用線性規(guī)劃的思想建立了合理的數(shù)學(xué)模型，同時將EJB構(gòu)件引入燃料配煤規(guī)劃中，提出基于構(gòu)件的多層結(jié)構(gòu)的燃料配煤規(guī)劃系統(tǒng)的開發(fā)思想，最后實現(xiàn)了基于EJB技術(shù)的可用于指導(dǎo)入廠煤采購及入爐煤混配燃燒的燃料配煤規(guī)

2、劃系統(tǒng)。該系統(tǒng)在保證電廠安全穩(wěn)定運行的前提下，對降低電廠入爐煤成本，減少環(huán)境的污染，有著重要的意義。關(guān)鍵詞:EJB，配煤，優(yōu)化ABSTRACTInoureountry，5eleetricPowerente印rises，above70%oftheentireeostwasthefueleost.Therefe，howtedueethefueleostandblendeoalreasonablywasthemainwaytaisetheee
