英文摘要： Large scale MW wind turbine generators have been highlighted recently due to its economic benefit. In this project, the high temperature superconducting (HTS) technologies and permanent magnet motor(PM) technologies will be combined, a novel design of HTS/PM wind turbine generator will be proposed. In this proposal, a numerical analytical model of HTS/PM wind turbine generator with modern advance optimization algorithm will be applied. A design and multi-objective optimization platform will be built accordingly. The electrical-magnetic, thermal, mechanical field coupled FEM models will be built to analyze the behavior of the generator. A 30kW prototype will be manufactured and tested based on the design. The test result will be compared with the expected theoretical design results. The design will be optimized to improve the critical technologies such as: AC losses reduction in HTS coils and the cryogenic system of HTS coils. A complete design procedure will be achieved after this project. The proposed HTS/PM wind turbine generator has the inherent merits in terms of high efficiency and high power density. The research will promote the development of HTS and PM technology, therefore will provide important theoretical and practical foundation for further research.
