【摘要】：除了燃气轮机系统的变工况性能外，燃气轮机控制系统的性能还决定着整个系统的经济性和安全性能。为了保证燃气轮机系统安全和可靠的运行，不仅要提高燃气轮机本身的性能，，还一定要设计出更加可靠、有效的控制系统。正是因为燃气轮机控制系统具有非常重要的作用，国外几大著名燃气轮机制造公司分别推出了拥有自主产权的电站用燃气轮机控制系统，比较常见的包括GE公司推出的SPEEDTRONICTMMark控制系统，西门子公司研发的TELEPER XP/3000控制系统等。目前国内的燃气轮机电站大多数都直接进口国外的控制系统，而国外各大公司均将控制技术列为不能转让的核心技术之一。随着我国在燃气轮机技术方面研究的不断深入，以及燃气轮机国产化的迫切要求，研发拥有我们国家自主知识产权的燃气轮机控制系统势在必行。本文以某型号电站用单轴燃气轮机为研究对象，先建立电站用燃气轮机全工况性能仿真模型，模型的稳态运行结果与试验数据相吻合，验证了模型的准确性。本文还分析了电站用燃气轮机的控制系统，对控制系统中各个子模块的控制逻辑算法进行详细分析，并进行简化的控制器设计。在此基础上，在Matlab/Simulink仿真平台上分别搭建燃气轮机及其控制系统仿真模型，进行系统的动态性能仿真试验。仿真结果符合燃气轮机实际运行规律，证明了模型的合理性与可用性；同时通过仿真试验的结果的分析，证明本文所设计的燃气轮机控制器能够满足燃气轮机控制要求，可以用来作为进一步研发的基础。
[Abstract]:In addition to the variable operating performance of the gas turbine system, the performance of the gas turbine control system also determines the economic and safety performance of the whole system. In order to ensure the safe and reliable operation of the gas turbine system, it is necessary not only to improve the performance of the gas turbine itself, but also to design a more reliable and effective control system. It is precisely because the gas turbine control system plays a very important role that several famous foreign gas turbine manufacturing companies have launched the gas turbine control system for power stations with their own property rights. The more common include GE SPEEDTRONICTMMark control system, Siemens developed TELEPER XP/3000 control system and so on. At present, most of the domestic gas turbine power stations are directly imported into foreign control systems, and foreign companies have listed the control technology as one of the core technologies that can not be transferred. With the deepening of gas turbine technology research in China and the urgent requirements of gas turbine localization, it is imperative to develop gas turbine control system with our own intellectual property rights. In this paper, a single-shaft gas turbine for a power station is taken as the research object. The simulation model of the full working condition performance of the gas turbine for power station is established. The steady-state operation results of the model are in good agreement with the experimental data, and the accuracy of the model is verified. The control system of gas turbine for power station is also analyzed in this paper. The control logic algorithm of each sub-module in the control system is analyzed in detail, and the simplified controller design is carried out. On this basis, the simulation models of gas turbine and its control system are built on Matlab/Simulink simulation platform, and the dynamic performance simulation test of the system is carried out. The simulation results are in accordance with the actual operation law of gas turbine, which proves the rationality and availability of the model. At the same time, through the analysis of the simulation results, it is proved that the gas turbine controller designed in this paper can meet the requirements of gas turbine control and can be used as the basis of further research and development.
