Research on Power Generation Efficiency of Hybrid Linear Switched Reluctance Generator

针对在海洋环境下低速运行的传统直线开关磁阻发电机发电效率较低的问题,本文提出了一种新型混合直线开关磁阻发电机,将永磁体按规定尺寸加入传统直线开关磁阻发电机动子的齿间。对此混合直线开关磁阻发电机进行有限元建模,分析其磁感线分布;在此基础上分析发电机的结构特点和工作原理,建立发电数学模型,并以此发电机为被控对象,利用Ansys Simplorer和Ansys Maxwell搭建联合仿真发电系统,最后通过仿真数据对传统直线开关磁阻发电机与混合直线开关磁阻发电机的发电效率进行对比分析。分析结果表明,混合直线开关磁阻发电机发电效率较传统直线开关磁阻发电机提高了10.64%。

Since there is poor generation efficiency in low speed linear switched reluctance generator in marine environment, a novel hybrid linear switched reluctance power generator was proposed, by introducing the permanent magnets into the mover of the traditional linear switched reluctance counterpart. The finite ele- ment model of the proposed generator was established to analyze the flux distributions, and then the mathe- matical model was derived based on the characteristics and working principle of the generator. The whole system utilized Ansys Simplorer and Ansys Maxwell to establish a joint simulation power generation system. Finally, the efficiency of traditional linear switched reluctance generator and hybrid linear switched reluc- tance generator was analyzed and compared through the simulation data. The analysis results show that the efficiency of the hybrid linear switched reluctance generator is 10. 64% higher than that of the traditional lin- ear switched reluctance generator.
