航空整流感应式无刷电励磁同步发电机的研究

The main power supply for the civil aircraft is taken as the research object. A Rectified and Induced Brushless Electrical Excitation Synchronous Generator (RIB-EESG) is proposed in this project. Compared with the current brushless excitation generators of the civil aircraft, the advantages of the three-stage brushless excitation synchronous generator are maintained. The RIB-EESG can overcome the complex structure of the three-stage brushless excitation synchronous generator. It also has the advantages, such as simple structure and convenience of magnetic flux adjustment. The operating principle and structure of IRB-EESG is analyzed. The method for the analysis of the machine with the coupled magnetic field is refined. The function of the rotor excitation current is deduced. The design strategy of the optimization of excitation efficiency is studied. The operational characteristics in the aero application is studied. The analysis of losses and thermal analysis are also carried out. The above-mentioned studies provide basic theory support to the aero brushless excitation ac machine. The theory and design method for the high-performance brushless excitation is also formed. This project is the multi-knowledge crossed research. It can be applied not only in the application of the aircraft, but also in the other field, such as wind power generation, gas turbine generation, nuclear power generation and so on.
