Electricity and heat cogeneration from geothermal sources : master's thesis

Geotermalne elektrane s binarnom tehnologijom temeljenom na organskom Rankineovom ciklusu i kaskadnim iskorištavanjem energije uz pridruženi centralizirani toplinski sustav omogućavaju pouzdanu, klimatski neutralnu i isplativu suproizvodnju električne i toplinske energije na područjima povoljnog geotermalnog potencijala, kao što je velik dio panonskog dijela Republike Hrvatske. Ovaj diplomski rad bavi se programskim modeliranjem i proračunom svih temeljnih tehnoloških procesa na takvom postrojenju korištenjem programskog jezika Python i pripadajućih modula i baza podataka. Model predviđa rad postrojenja unutar jedne kalendarske godine s prosječnim temperaturnim uvjetima.Geothermal power plants with binary technology based on the organic Rankine cycle and cascade energy utilization with associated central heating system enable reliable, climate-neutral and cost-effective cogeneration of electricity and heat in areas with favorable geothermal potential, such as much of the Pannonian part of the Republic of Croatia. This thesis deals with program modelling and calculation of all basic technological processes in such plants, using the Python programming language and associated modules and databases. The model predicts the operation of the power plant within one calendar year at average temperature conditions
