Sažetak
Although development in electrical power production continuously shifts to renewables, power plants based on conventional fuels should not be neglected. Market requirements and their operational flexibility are just some of the reasons for this kind of plant to be worth investigated and explored. In this paper, the combined cycle power plant is analyzed. Analyzed plant size and operating parameters were based on an existing plant located in the north of Croatia. The power plant consists of two blocks that can operate independently of each other. Each block consists of 30 MWe gas turbine and 10 MWe steam turbine. The gas and steam part of the plant is connected with a heat recovery steam generator where the flue gases from the gas turbine deliver heat to the water and the steam which are then used in the steam turbine part of the process. In this paper thermal calculation of a combined cycle power plant is performed. The technical description of the energy system is followed by the energy balance calculation of the gas turbine and the energy balance equation of the steam turbine. Calculations are made in two ways, analytically by standard thermodynamic procedures and by using modern commercial computer-based calculation software. The results obtained by both methods are analyzed and compared, followed by discussion and conclusion.
