Operation parameters analysis of gas steam combined cycle

Abstract

Taking a three-pressure reheated gas-steam combined cycle unit as the research object, the detailed efficiency calculation model of gas turbine and heat recovery steam generator was established, and the influence of various thermal parameters of gas turbine and heat recovery steam generator on efficiency was analyzed. Using MATLAB software programming, the relationship between the efficiency of gas turbine and heat recovery steam generator with various thermal parameters is obtained, and the sensitivity of gas turbine and heat recovery steam generator efficiency to various thermal parameters is analyzed, and the thermal parameters that have the greatest impact on efficiency are found. Optimized operation of power plant parameters plays a guiding role.
