[Abstract]:Class F advanced gas turbine units have been widely used in the field of clean power generation technology, in order to effectively improve the operating safety and reliability of the units, Multi-level modeling and analysis of gas turbine system, especially combustion chamber, is needed. Firstly, the whole modular modeling method is adopted in this paper, and the M701F unit of Mitsubishi Company is taken as the research object, and the measured data of the unit are combined. The design / off-design performance of gas turbine is studied, and the influence of environmental conditions, such as IGV control and exhaust temperature, on the performance of the unit is studied. Combined with the results of system model analysis, For the advanced multi-nozzle swirl combustor of the unit, a linear network model is built to study the thermoacoustic stability of the combustion chamber. The results show that there are many modes such as plane and circumferential acoustic waves in the combustion cylinder. The characteristics of M701F unit are in good agreement with the actual characteristics. The influence of the bypass valve structure of M701F unit on the modal stability of the combustion chamber is further analyzed.
