通过铈磁体双主相技术、晶界调控技术等,开发了风电用铈磁体,并以直驱1.5 MW永磁风力发电机为工程案例开展了仿真和分析,特别是磁钢厚度的适应性设计。样机的型式试验中,对比设计值与实测值的相符度及各项性能指标的达标性,验证铈磁体在风电中应用的可行性,以及发电机总体设计方案的可行性,均能够满足机组工程化需求。1.5 MW铈磁体样机的开发,为后续更高性能铈磁体在风电中的开发和应用打下了良好的基础,并提供了重要的参考依据。

Cerium magnets for wind power were developed through the dual main phase technology of cerium magnets and grain boundary control technology.Simulation and analysis were conducted using a direct drive 1.5 MW permanent magnet wind turbine as an engineering case,especially the adaptive design of magnetic steel thickness.In the type test of the prototype,the consistency between the design values and the measured values,as well as the compliance of various performance indicators,were compared to verify the feasibility of the application of cerium magnets in wind power and the feasibility of the overall design scheme of the generator,which could meet the engineering requirements of the unit.The development of a 1.5 MW cerium magnet prototype had laid a good foundation for the subsequent development and application of higher performance cerium magnets in wind power,and provided important reference basis.
