[Abstract]:The performance analysis and optimization research of gas-steam combined cycle unit is of great significance for the optimization operation and energy-saving reconstruction of gas-fired unit. In this paper) The performance analysis and multi-objective optimization of gas-steam combined cycle units are carried out by means of analytical method, and the optimal distribution of thermoelectric load among different types of combined cycle units is discussed. The main contents are as follows: first, The main components of gas-steam combined cycle unit are established. The calculation model is analyzed and the design and operation conditions of the unit are obtained. Loss distribution, and under different gas turbine load, ambient temperature, heat supply to the unit under different conditions. The variation law of unit and its components under different working conditions is obtained, which provides a theoretical basis for deep energy saving of the unit. Secondly, according to) Based on the economic theory, the cost model of combined cycle unit is established. With the goal of the highest efficiency, the lowest total cost and the minimum CO2 emission, the multi-objective optimization of the combined cycle unit is carried out by using NSGA 鈪，
