摘要
本文对开关磁阻发电机(SRG)发电过程进行了详细的分析推导,基于精确的SRG仿真模型,结合了角度位置与电流斩波控制(APC-CCC),运用更加直观的三维图形分析了开关角、电流斩波限和转速等参数对励磁惩罚的复杂非线性影响。根据仿真结果得到了在不同电流斩波限与转速下的最佳开关角与相应的控制策略,将其应用于SRG性能优化。仿真结果表明,所得到的优化控制器是有效的,并为不同情况下SRG进行最佳能量转换提供了控制策略。
A detailed analysis on power generation of SRG was presented in this paper. The simulation based on accurate SRG simulation model. APC and CCC were combined in the simulation. The complex nonlinear effect of switching angle,current chopping limit and rotate speed on excitation penalty were analyzed by intuitive three-dimensional figure. According to the simulation,the optimum switching angles and control strategies were obtained in different current chopping limits and various speeds. The optimum datum were used in optimization process. Simulation results were presented to prove the effectiveness of the controller and provided control strategies for the energy conversion ratio of SRG in different situations.
