Abstract
Tehnologija proizvodnje električne energije u postrojenjima s Rankineovim ciklusom koja kao primarni izvor energije koriste sunčevu energiju tzv. solarnim termoelektranama intenzivnije se razvija u mediteranskim zemljama i SAD-u od 2006. godine zahvaljujući poticajnim tarifama. Trenutno su najraširenija postrojenja u kojima se izravno sunčevo zračenje usmjerava pomoću paraboličnih zrcala na cijev u kojoj struji i zagrijava se termičko ulje. Vruće termičko ulje koristi se za proizvodnju vodene pare, radnog medija u Rankineovom ciklusu. Suvremene solarne termoelektrane uobičajeno se izvode s toplinskim spremnikom te s dodatnim zagrijačem jednog od radnih medija koji omogućavaju produljenje pogona na nazivnoj snazi i u uvjetima smanjenog sunčevog zračenja. Rad se bavi problematikom modeliranja termohidrauličnih procesa u solarnoj termoelektrani. Opisani su glavni dijelovi konvencionalne solarne termoelektrane. Razvijen je matematički model dinamike termohidrauličkih procesa u solarnoj termoelektrani. Obrazložena je potreba i značaj, te su opisani koncepti regulacije temperature termo ulja u kolektorskom sustavu. Uspoređeni su različiti koncepti vođenja postrojenja solarne termoelektrane pomoću rezultata simulacije matematičkog modela. Pokazano je da hibridni koncept sa dodatnim zagrijačem i spremnikom topline omogućava približno kontinuirani pogon postrojenja u većem dijelu dana. Provedena je detaljna numerička analiza naprezanja u cijevnoj stijeni pregrijača pare.
Abstract (english)
Due to establishment of incentive framework, technology of energy production in solar Rankine cycle power plants has been more intensively developed in USA and Mediterranean countries since 2006. In most common configuration of solar thermal power plants parabolic mirrors are used for concentration of solar irradiation onto absorber tube and for heating of thermal oil. Hot thermal oil is further used to produce superheated steam, working fluid in conventional Rankine cycle. State of the art solar thermal power plants are equipped with heat storage system and additional burner of fossil/or renewable fuels enabling increase of power plant production even in conditions of lower solar irradiation. This paper deals with mathematical modeling of thermo hydraulic processes in solar power plant. Main components of conventional solar thermal power plant have been described and theirs mathematical models have been developed. Various concepts of thermal oil temperature control have been analyzed. Simulation of solar power plant operation in typical meteorological conditions has been performed and different operation strategies have been compared. It has been shown that configuration with ancillary burner and thermal storage enables approximately continuous operation of solar plant. Detail numerical analysis of stresses occurring in superheater tube sheet has been performed.
