摘　　要：为了解决永磁轴承的悬浮力不可控、安装精度高、所需空间大等问题,采用混合磁轴承作为水平轴风力发电机主轴系统的径向支承,在介绍结构形式与数学模型的基础上,对风力发电机转子系统进行了受力分析,并对径向混合磁轴承的结构参数和数字控制系统进行设计,构建了磁悬浮实验平台,完成了静态起浮和扰动试验。试验结果表明,试验样机参数设计正确,数字控制系统软、硬件设计合理,径向混合磁轴承系统性能稳定,为小型风力发电机磁悬浮支承技术的研究提供了参考。In order to solve the problems of uncontrollable levitation force, high assembling accuracy, and the larger space, radial hybrid magnetic bearing（RHMB） as the supporting structure of spindle system of horizontal axis wind power generator, was proposed in this paper. On the basis of introducing structure and mathematical model, the mechanical analysis on rotor system of wind power generator was carried out, the structural parameters and digital control system of RHMB were designed, the experimental platform of RHMB was built. Finally, the starting up and disturbance experiments were completed. The experimental results show that the parameters of the experimental prototype is correct, software and hardware design of digital control system are reasonable, and the performance of RHMB system is stable. It provides reference for studying on magnetic suspension technology of small wind power generator.
