Mathematical Model and Steady State Performance Analysis of Double-fed Machine

介绍了基于三相坐标系情况下,双馈电机及其循环变流器的数学模型。在所建数学模型的基础上,给出了应用所建数学模型计算得到的双馈电机稳态运行特性波形。同时对波形进行了频谱分析,指出了电压谐波成分对双馈电机稳态性能的影响情况。

The paper introduces the mathematical model of the double-fed machine and its cycloconverter based on three-phase coordinate system. By using this mathematical model,we can calculate the steady state performance wave form of the double-fed machine. At the same time the paper analyses the frequency spectrum of the wave from, and indicates the influence of voltage harmonic wave component on the steady state performance.
