基于RMxprt Maxwel l的SRG低速电流斩波控制研究

摘要

基于 Ansoft/RMxprt 和 Maxwell的仿真环境，建立开关磁阻发电机仿真模型，采用有限元分析，研究其静态和动态特性；研究旋转电机优化设计方法，指导开关磁阻发电机及其控制系统优化设计。采用低速段电流斩波控制，得到最佳开通角、关断角、转速、和电流滞环控制宽度等参数，指导样机发电实验，增加发电输出功率，提高 SRG发电系统稳定性。%The module of 8/6 phase switched reluctance generator was built under Ansoft/RMxprt and Maxwell.The basic static performance and dynamic performance of SRG were analyzed based on the model by finite element analysis;The results of optimization design of rotating electrical machines can be available used to design and optimize the new type ma-chine and its control system.In low velocity,a new type current chopping controller is adopted,the control parameters can be got,such asθon ,θoff ,velocity and current chop control width,so the prototype machine can be achieved,and the output power can be enlarge,and the stability of SRG power system can be increased.
