摘　　要：分析了谐波电流对同步发电机内部磁场的影响,利用能量法推导出电磁转矩在电枢电流含有谐波时的解析式,并从电磁转矩脉动的角度论述了非线性负载使小容量发电机组轴产生机械振动的机理。进行了柴油发电机组带非线性设备的实验,对机组的震动、噪声、频率信号进行测量。This article analyses the influence of harmonic current to the magnetic field inside the synchronous generator, deduces a formula that can describe the electromagnetic torque pulsation brought by harmonic current by use of energy method, and states the mechanism of machinery vibration caused by low-capacity power unit axes. Experiment is taken for the diesel generator with non-linear equipment, and measurement is done to the unit on vibration, noise and frequency signal.
