【摘要】：本文介绍了燃气轮机发电以及燃气蒸汽联合循环发电的发展过程,以及其各自的发电原理和热力循环过程,论述了研究燃气轮机发电以及对燃气轮机本体进行建模仿真研究的现实意义。在学习和借鉴国内外研究成果的基础之上,以北京某燃气热电有限公司引进的西门子SGT5-4000F型燃气轮机为研究对象,结合本文建模仿真研究的目的和特点,对该燃气轮机进行了简化分析,将燃气轮机分为压气机、燃烧室、和透平三个主要部分,分别对其各自的结构特点和工作原理进行了详细的介绍。采用模块化建模的思想和机理建模的方法,结合计算机仿真技术建立了燃气轮机中这三个模块的仿真模型,进而得到燃气轮机的仿真模型。采用Borland C++build对燃气轮机中这三个模块的仿真模型算法编制了相应的仿真程序,利用仿真机相对应的Algmanager软件将所编写的模型算法与相应的图形相连接,并入库到PAnySimu仿真平台上构建燃气轮机仿真模型的主要算法库。基于该仿真平台,充分利用所建立的燃气轮机仿真算法库,搭建了燃气轮机的仿真模型,并对所建模型进行了扰动实验,研究其相应的动态特性。研究结果表明所加各扰动的动态特性符合电站用燃气轮机的过程机理,从而验证了所建模型的正确性与合理性。此外,所建模型可以为燃气轮机的特性研究提供工具,同时其与电站运行所需的其他算法相结合可以搭建成燃气蒸汽联合循环发电过程的仿真平台,为燃气蒸汽联合循环运行人员的训练提供平台,具有很强的实用价值。
[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.
