Abstract
The paper presents the thermodynamic model of the GE LM6000-PF gas turbine with a heat recovery hot water boiler. The maximum electrical power output of the unit is 50 MWe. The turbine is a part of a real cogeneration heat and power plant. The model was developed in the Ebsilon Professional software. The operating parameters of the gas turbine strictly depends on the off-design conditions such as the air flow properties. The outcome from the model can be used to short-term planning of energy production in the plant. Basic production parameters such as electric power, heat production in the recovery boiler, fuel consumption are needed to be forecasted for the upcoming day in an hourly resolution. In this paper, the procedure for validating was presented. The method uses the correction coefficients, determined based on the real data aggregated during the operation of the unit. Correction for electricity production, heat rate, mass flow rate and temperature of flue gas was proposed to increase the accuracy of the model. The accuracy of the calculation of heat output produced in the boiler was increased by correcting the coefficient of heat transfer in off-design conditions. The results in the form of an hourly gas turbine parameters were presented and compared with real ones coming from several months of the system operation. The mean percentage error of the model was reduced with the use of corrections factors to approximately 0.8% and 1.3% for electric power and recovered heat, respectively.
