本文介绍了用于直接驱动海洋波浪能转换 (WEC) 的低成本但高功率密度管状线性开关磁阻发电机 (TLSRG) 的性能特征。所提出的 TLSRG 由一系列软磁环组成,比传统齿型 TLSRG 具有更高的功率密度。每个定子槽内只有一组圆形绕组,便于制造工艺,从而降低了成本。所提到的环段彼此磁隔离和电隔离,因此减少了相位耦合并提高了容错能力,有利于像WEC一样在恶劣条件下使用。对 WEC 模式下的特性和动态性能进行了检查和讨论,验证了所提出的 TLSRG 是 WEC 永磁管式发电机的有力替代候选者。
This paper presents the performance characteristics of a low cost but high-power density tubular linear switch reluctance generator (TLSRG) for direct drive marine wave energy conversion (WEC). The presented TLSRG consists of series of soft magnetic rings and exhibits higher power density than conventional teeth type TLSRG. There is sole set of round winding in each stator slot, which facilitates manufacturing process, thus, results in low cost. The referred ring segments are both magnetically and electrically isolated with each other so it reduces the phase coupling and increase the capability of fault tolerance that is favorable to be used in harsh conditions as WEC. The characteristics and dynamic performance at WEC mode are examined and discussed, validating that the presented TLSRG is a strong alternative candidate to permanent magnet tubular generator for WEC.
