Abstract
The paper presents the problem of forecasting the operation condition of LM6000-PF gas turbine with a heat recovery hot water boiler in off-design mode. The presented unit is part of a real cogeneration heat and power plant. The maximum electrical power output for nominal conditions of the case study unit is 50 MWe. The proposed method is based on the thermodynamic modeling supplied with a data-driven model. The prediction model uses correction factors determined based on the real operating data. Correction factors for electricity production, heat rate, flue gas mass flow rate, and overall heat transfer coefficient in the boiler are proposed to increase the accuracy of the prediction results. The outcome from the model can be used for short-term planning of energy production in the case study combined heat and power plant. Here, fundamental production parameters such as electric power, heat production in the recovery boiler, and fuel consumption must be forecasted for the upcoming day in an hourly resolution. The results in the form of hourly parameter changes are presented and compared with real ones from two years of the system operation. The model's mean percentage error was reduced by using corrections factors to approximately 0.8% and 1.7% for electric power and recovered heat, respectively.
