[Abstract]:This paper introduces the development process of gas turbine power generation and gas-steam combined cycle power generation, as well as their respective generation principle and thermodynamic cycle process. The practical significance of research on gas turbine power generation and modeling and simulation of gas turbine body is discussed. On the basis of studying and drawing lessons from domestic and foreign research achievements, taking Siemens SGT5-4000F gas turbine imported by a gas thermal power co., Ltd in Beijing as the research object, combined with the purpose and characteristics of modeling and simulation research in this paper, The gas turbine is divided into three main parts: compressor, combustor and turbine. Their structure characteristics and working principle are introduced in detail. The simulation model of these three modules in gas turbine is established by using the idea of modular modeling and the method of mechanism modeling, combined with computer simulation technology, and the simulation model of gas turbine is obtained. The corresponding simulation program of the simulation model algorithm of the three modules in the gas turbine is developed by using Borland C build, and the model algorithm is connected with the corresponding graph by using the corresponding Algmanager software of the simulation machine. The main algorithm library of gas turbine simulation model is built on PAnySimu simulation platform. Based on the simulation platform, the simulation model of gas turbine is built by making full use of the gas turbine simulation algorithm library, and the disturbance experiment is carried out to study the corresponding dynamic characteristics of the model. The results show that the dynamic characteristics of each disturbance are in line with the process mechanism of the gas turbine for power station, and the correctness and rationality of the model are verified. In addition, the model can provide a tool for the study of gas turbine characteristics, and it can be combined with other algorithms needed for power station operation to build a simulation platform for gas-steam combined cycle power generation process. It is of great practical value to provide a platform for the training of gas-steam combined cycle operators.
