开关磁阻电机调速系统整体稳态性能分析方法研究

Method Used to Analyze SRD's Steady-State Performance

开关磁阻电机调速系统(SRD)的运行机理比较复杂,以往对其稳态性能的研究一般侧重于电机本身,对系统其它重要组成部分如功率变换器中的整流桥、功率变换电路等则很少涉及。因此,SRD的一些重要性能指标如功率因数、效率等难于准确地计算。本文从系统角度出发,建立了全系统的数学模型,该模型可以用来准确计算系统的稳态性能,计算结果为实验结果所证实。

Because of the complexity of the switched reluctance motor drive, previous work analyzed only the motor's model and performance, without paying any attention to other important parts, such as convertor and rectifier. So, the power factor and efficiency of the drive can't be calculated accurately. At the first time, this paper presents a model for the SRD to deal with motor and convertor as one unit. Accurate performance predictions can be done on the basis of the model. The calculating results and experiment results confirm the model.
