Abstract

Kombinirani plinsko/parni proces je tehnologija za proizvodnju energije čije su glavne prednosti viša učinkovitost i niže emisije stakleničkih plinova u odnosu na klasične termoelektrane. Te elektrane proizvode električnu energiju sagorijevanjem plina, pri čemu se ispušni dimni plinovi, koji su posljedica izgaranja plina, koriste za proizvodnju dodatne električne i toplinske energije. Primjer takve elektrane u Republici Hrvatskoj je blok C TE Sisak. Na temelju poznatih veličina elektrane i komponenata od kojih je sačinjena razvijen je matematički model sinkronog generatora plinske turbine snage 190 MVA, njegovog blok-transformatora i sustava za regulaciju uzbude. Na temelju matematičkog modela razvijen je simulacijski model, na kojem su obavljeni pokusi vezani uz promjenu djelatne i jalove snage.

Abstract (english)

The combined gas-steam power cycle is a technology for power production whose main advantages are a higher degree of efficiency and lower emissions of greenhouse gases compared to conventional thermal power plants. These power plants produce electrical energy by burning gas, whereby the exhaust flue gases, which are the product of combustion, are used to produce more electrical and thermal energy. An example of such a power plant in the Republic of Croatia is the Block C of the thermal power plant Sisak. A mathematical model has been designed based on the known parameters of the power plant and its components, which include the synchronous generator of the gas turbine (190 MVA), its step-up transformer and its excitation system. The mathematical model has been used to develop a simulation model, which was then used to perform experiments which involve changes in the output of both active and reactive power.
