Izboljšanje gospodarnosti toplarne na premog s prigraditvijo plinske turbine : magisterijPerovič, OlgicaNa podlagi matematičnega postopka optimiranja je tehnično in ekonomsko obravnavan problem revitalizacije energetskega sistema toplarne na premog (kombinirana proizvodnja toplote in električne ... energije ter sistem daljinskega ogrevanja). Pri določanju optimalnega načina obratovanja celotnega sistema je bil uporabljen model, ki vključuje tudi s projektom opredeljeno shranjevanje toplote (hranilnik toplote z atmosferskim tlakom). Revitalizacija zajema nadomestitev parnega kotla s prigraditvijo plinskega turboagregata in utilizatorja z dodatnim kurjenjem obstoječemu odjemno-protitlačnemu parnemu turboagregatu. Obravnava je ponazorjena s primerom Termoelektrarne-Toplarne Ljubljana. Optimizacijski problem iskanja najbolj ekonomičnega obratovanja toplarne je bil opredeljen kot dinamičen, formuliran kot problem mešanega celoštevilskega 0-1 linearnega programiranja (0-1 MCLP) in rešen z metodo vejanja in omejevanja. Na podlagi rezultatov optimizacijskega problema za dve velikosti plinskih turbin je predlagana odločitev o optimalni investiciji toplarne. Z dinamičnimi kriteriji ekonomskega vrednotenja variant je ugotovljena ekonomska utemeljenost investicije, z analizo občutljivosti pa so določeni tisti vhodni podatki, ki na njo najbolj vplivajo.Type of material - master's thesisPublication and manufacture - Ljubljana : [O.
