计及空间分数次谐波影响的同步电机支路模型

A Branch Model of the Synchronous Machines Considering the Effect of the Fractional Order Space Harmonics

本文提出了一种能充分计及空间各种不同性质谐波的同步屯机支路模型．在这种模型中，定子以每条并联交路为单元，阻尼绕组以各实际回路为单元建立了其相应的基本支路方程，它既可以适用于分析各类同步电机分数次空间谐波的作用，还可以适用于分析发电机多种故障运行．因而具有很大的灵活性．

A branch model of the synchronous machines, in which the harmonic of various natures in the airgap magnetic field can be considered fully, is present. in this paper. In this modcl, its basic equations arc consist or the equation of cach paralleled branches of the stator and the real damper loop or the rotor. This model can be suited to analyze the effcct or the fractional space harmonics and the internal Failures or the synchronous machines. Thcrcforc, it is effcctivc to be uscd.
