The paper describes a synchronous generator model developed based on the multiple reference frame theory. The main physical phenomena included in the model are the machine armature non-sinusoidal voltage waveform and the influence of armature current in load conditions on the armature voltage waveform higher harmonic components. The modified multiple reference frame theory model is proposed. In this modified theory model the field and armature currents are the cause of the non-sinusoidal airgap spatial field distribution. The influence of this airgap spatial field distribution is also investigated. The resulting nonuniform saturation of the pole shoe affects the machine voltage waveform in load conditions. Simulation and measurements of the machine performance in steady and transient states are conducted in order to validate the model.

考虑非均匀极靴饱和引起的谐波失真的同步发电机模型中的多参考系理论

本文描述了一种基于多参考系理论开发的同步发电机模型。模型中包含的主要物理现象是电机电枢非正弦电压波形和负载条件下电枢电流对电枢电压波形高次谐波分量的影响。提出了修正的多参考系理论模型。在这个修正的理论模型中,场和电枢电流是非正弦气隙空间场分布的原因。还研究了这种气隙空间场分布的影响。由此产生的极靴不均匀饱和会影响负载条件下的机器电压波形。进行稳态和瞬态下机器性能的仿真和测量,以验证模型。
