博士论文主题为建立Microturbine数学模型

The thesis describes the development of a dynamic model of a microturbine system. The thesis is done in close cooperation with Turbec AB and the model is adjusted, tuned and verified against their microturbine T100. The microturbine unit consists of a compressor and a turbine connected on a single shaft to a high-speed generator. Moreover there is a combustion chamber, a recuperator and a gas/water heat exchanger. A control system regulates the speed, the temperature and the electric power. To control the frequency, voltage and current of the outgoing power, the microturbine uses power electronics. The model is to be used in the research and development department at Turbec AB. Possible applications are in areas as control strategies, dynamic performance verification, operator training and control software/hardware verification. Since the potential applications are so different, the emphasis throughout the thesis has been on a general model that can be used in as many different operating ranges as possible. This should be done while retaining a high degree of accuracy at the most common scenario, running on full load. The emphasis has also been on the functionality and accuracy of the complete model over more detailed modelling of each component
