摘要

本文讨论了变风条件下风电转换系统PMSG的电压调节问题。采用机械磁链变分技术(MFV)实现了卡曼型双定子轴向磁链永磁同步电机在额定转子/风速以上的自动转矩控制，扩大了发电机的转速范围。建立了在发电机上实现MFV的实验试验台，并分析了该技术对发电机性能的影响。通过FFT分析计算了该技术注入发电机输出的总谐波，并对正弦和梯形反电动势两种特性进行了比较。

Comparison of variable-flux PMSG for extended speed-range based on magnet arc-length to pole-pitch ratio

This paper discusses voltage regulation (VR) of PMSG for a wind energy conversion system (WECS) under varying wind conditions. Mechanical flux-variation technique (MFV) has been used for VR of a kaman-type dual-stator axial-flux PMSG at above rated rotor/wind speed extending the speedrange of generator. An experimental test-bed has been set up to implement MFV in the generator and subsequently, the implications of proposed technique on the performance of generator has been analyzed. Total harmonic injected in generator output due to proposed technique has been calculated by FFT analysis and compared for two types namely, sinusoidal and trapezoidal back-emf characteristics.
