摘要
传统电励磁发电机依赖滑环与碳刷系统,在高速运行时面临散热效率低下和机械强度不足的问题,限制了其在更广泛应用领域的拓展.随着永磁技术的不断发展,交错磁极混合励磁发电机因其宽广的调压范围和卓越的变速恒压能力,成为学术与工程领域的研究热点.本研究采用有限元仿真技术,对一种新型三段式定子辅助励磁交错磁极发电机的空载增去磁特性进行了深入分析.研究不仅精确评估了辅助励磁绕组对永磁发电机磁路布局的定量影响,还通过500 kW三段式混合励磁发电机的试验数据,验证了仿真分析的准确性.这些成果为混合励磁发电机的设计优化和性能提升提供了关键参考,为未来相关技术的发展奠定了坚实基础.
Abstract
The traditional electrically-excited generator relies on the slip rings and brush systems.It faces the issues of low heat dissipation efficiency and insufficient mechanical strength at high-speed operation,which limits their expansion in broader application fields.With the continuous development of permanent-magnet technology,the interleaving-pole hybrid-excitation generator has become a research hotspot in academic and engineering fields because of its extensive voltage regulation range and excellent variable-speed constant-voltage capability.This study employs the finite-element simulation technology to deeply analyze the no-load in-crease/decrease magnetization characteristics of a novel three-segment type of stator auxiliary-excitation interleaving-pole generator.It not only accurately evaluates the quantitative influence of the auxiliary-excitation windings on the magnetic circuit layout of the generator,but also veri-fies the accuracy of the simulation analysis through the test data of a 500 kW three-segment type of hybrid-excitation generator.These achievements provide some key references for the design optimization and performance enhancement of the hybrid-excitation generators,which lay a solid foundation for the future development of the related technologies.
