Modeling for wave power generating system based on linear switched reluctance machine

针对传统直线开关磁阻电机功率密度低,作为波浪能转换装置难以广泛应用的问题,设计一种采用高功率密度的互感耦合直线开关磁阻电机的波浪能转换装置。根据互感耦合直线开关磁阻电机的结构特点及运行原理,建立以互感耦合直线开关磁阻电机为波浪能转换装置的波浪发电系统仿真模型,并对电机典型位置时刻的磁场进行分析。采用电压外环PI调节加电流内环斩波调节的双闭环控制策略对互感耦合直线开关磁阻电机波浪发电系统进行仿真分析。系统仿真结果表明:以互感耦合直线开关磁阻电机作为波浪能转换装置,能够达到波浪发电的目的。

The low power density was an obstacle of linear switched reluctance machine（LSRM） to be competitive candidates for the wave energy conversion.In order to solve the problem,the high power density mutually coupled linear switched reluctance machine（MCLSRM） was proposed in this paper.According to the structure and principle of MCLSRM,a simulation model of wave power generating system was established,and the magnetic analysis of the typical positions was made.The variable parameters voltage PI control and current chopped control were used in the simulation of wave power generating system based on MCLSRM.The simulation results of the system show that MCLSRM achieves wave power generating well as a wave energy converter.
