电厂发电机的谐波危害分析与测试

Analysis and Test of Harmonic Harm of the Gnerator in the Power Plant

电力系统中的谐波污染日益严重,会对电厂发电机带来一系列的危害,分析了谐波影响下的发电机等效模型建立方法,以及发电机的谐波电压与电流,计算出了发电机在谐波影响下的稳定电磁转矩与脉动电磁转矩,最后对实验发电机进行了测试,分析了谐波对电厂发电机的危害。

The harmonic pollution in the power system can bring the generator much harm. The equivalent model toothed of the generator and harmonic voltage and current of the generator are analyzed. The stable electromagetic torque and pulsating electromagnetic mental generator is tested and torque of the generator under the haumonic influence are worked out. Finally, the experi- analyzes the harmonic to the generator of the power plant.
