摘要

介绍了非线性负载引起的电压畸变的计算方法和减小电压畸变的设计思想。分析了减小转子结构和阻尼器绕组的显著性对发电机谐波电流阻抗的影响。结果表明，非线性负载下的发电机电压畸变可以通过以下两种方法中的一种来控制:提高发电机的额定值，使非线性负载占发电机额定值的百分比更小;或将发电机的内部阻抗减小到非线性负载电流的谐波。

Voltage distortion of rotary UPS and standby engine generator sets

Methods for calculating the voltage distortion produced by nonlinear loads, and design concepts for reducing the distortion are described. The impact of reducing saliency in the rotor construction and in the damper windings on the impedance of the generator to harmonic currents is analyzed. It is shown that generator voltage distortion under nonlinear loads can be controlled by either one of two methods, overrating the generator to make the nonlinear load a smaller percentage of the generator rating, or reducing the internal impedance of the generator to the harmonics of the nonlinear load current.<>
