摘要
多相电机相比传统三相电机,具有较高的可靠性,较低的转矩脉动等优势,在船舶电力推动和低压大功率方向有很好的发展潜力。目前对多相电机的仿真建模研究多基于信号流模式。本文以双三相感应电机为例,在分析其数学模型的基础上,提出了双三相感应电动机基于线性变压器和受控电流源仿真建模的新方法。所搭建的双三相感应电机模型可以作为Matlab/Simul i nk电力模块系统模块库中的元件进行直接调用。仿真结果证明了模型的准确性和有效性。
Compared with the conventional three-phase induction machine,the multiphase induction machine has the advantage of higher reliability and lower torque pulsation.The multi-phase induction machine has a good development potential in shipping power propulsion and low-voltage high-power applications.At present modeling and simulation of the multi-phase induction machine are mostly based on signal flow.Based on the mathematical model of the three-phase induction machine,a new method for modeling and simulation of the dual three-phase induction machine control system in Matlab is proposed.The model of dual three-phase induction machine can be used as an element of SimPower Systems Block.The reasonability and validity have been testified by the simulation results.
