【摘要】：除了燃氣輪機系統(tǒng)的變工況性能外，燃氣輪機控制系統(tǒng)的性能還決定著整個系統(tǒng)的經(jīng)濟性和安全性能。為了保證燃氣輪機系統(tǒng)安全和可靠的運行，不僅要提高燃氣輪機本身的性能，，還一定要設(shè)計出更加可靠、有效的控制系統(tǒng)。 正是因為燃氣輪機控制系統(tǒng)具有非常重要的作用，國外幾大著名燃氣輪機制造公司分別推出了擁有自主產(chǎn)權(quán)的電站用燃氣輪機控制系統(tǒng)，比較常見的包括GE公司推出的SPEEDTRONICTMMark控制系統(tǒng)，西門子公司研發(fā)的TELEPER XP/3000控制系統(tǒng)等。 目前國內(nèi)的燃氣輪機電站大多數(shù)都直接進口國外的控制系統(tǒng)，而國外各大公司均將控制技術(shù)列為不能轉(zhuǎn)讓的核心技術(shù)之一。隨著我國在燃氣輪機技術(shù)方面研究的不斷深入，以及燃氣輪機國產(chǎn)化的迫切要求，研發(fā)擁有我們國家自主知識產(chǎn)權(quán)的燃氣輪機控制系統(tǒng)勢在必行。 本文以某型號電站用單軸燃氣輪機為研究對象，先建立電站用燃氣輪機全工況性能仿真模型，模型的穩(wěn)態(tài)運行結(jié)果與試驗數(shù)據(jù)相吻合，驗證了模型的準確性。本文還分析了電站用燃氣輪機的控制系統(tǒng)，對控制系統(tǒng)中各個子模塊的控制邏輯算法進行詳細分析，并進行簡化的控制器設(shè)計。在此基礎(chǔ)上，在Matlab/Simulink仿真平臺上分別搭建燃氣輪機及其控制系統(tǒng)仿真模型，進行系統(tǒng)的動態(tài)性能仿真試驗。仿真結(jié)果符合燃氣輪機實際運行規(guī)律，證明了模型的合理性與可用性；同時通過仿真試驗的結(jié)果的分析，證明本文所設(shè)計的燃氣輪機控制器能夠滿足燃氣輪機控制要求，可以用來作為進一步研發(fā)的基礎(chǔ)。
[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.
