Termoenergetski preizkusi termoelektrarn : magistrsko deloMarđetko, LenartTermoenergetski preizkusi termoelektrarn so pomemben dejavnik pri zagotavljanju učinkovitosti in zmanjševanju specifičnih porab v termoelektrarnah. Meritve pri takih preizkusih se morajo izvajati pod ... nadzorovanimi pogoji po standardiziranih metodah, kar zagotavlja ponovljivost in primerljivost rezultatov. Ker se morajo takšne meritve izvajati pri konstantnih obremenitvah in konstantnih obratovalnih pogojih, so rezultati ocen kvalitete obratovanja praviloma boljši od dejanskih realnih vrednosti. Dejanska obremenilna stanja in dejanske vrednosti izkoristkov v opazovanem časovnem obdobju pokažejo, da lahko odstopanja znašajo tudi več odstotkov, vendar ne vedno enako in enoznačno. Razlog teh odstopanj so realni obratovalni pogoji, spreminjanja obratovalne točke med obratovanjem, kvalitete goriva, spreminjanje parametrov okolice, itd. V nalogi bodo na osnovi rezultatov termoenergetskih preizkusov, ki se periodično opravljajo v termoelektrarnah, ugotovljeni razlogi za odstopanja, predvsem s stališča neenakomernosti podatkov in hitrega spreminjanja moči in obratovalnih pogojev. S statističnimi metodami in primerjavo podatkov, dobljenih pri realnem obratovanju, bodo poiskani tisti parametri in nestacionarnosti, ki najbolj prispevajo k odstopanju ocen vrednosti kvalitete obratovanja. Na osnovi pridobljenih rezultatov bo mogoče opraviti bolj realne analize in napovedi obratovalne uspešnosti posameznih blokov v termoelektrarnah. Istočasno bo mogoče z ublažitvijo fluktuacij posameznih nestacionarnosti doseči taka obratovalna stanja, pri katerih bodo doseženi višji izkoristki termoelektrarn.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
