摘　　要：中小功率发电机采用自动电压调节器调节励磁电流具有电压稳态调整率小的特点,但是发电机带感性负载的电枢反应使得电压波形畸变率加大,本文阐述中小功率单相柴油发电机采用自动调速和无功补偿的双闭环控制,通过样机性能实测表明发电机具有电压波形畸变率小、电压和频率调整率小的特点,具有工程实用性。Small and medium power generator that adopt automatic voltage regulator to adjust the excitation current has characteristics such as smaller steady-state voltage regulation rate. But, the armature reaction of the generator with inductive load causes the voltage waveform distortion rate increase. This paper describes the small and medium power single-phase diesel generator with automatic adjusting speed and reactive power compensation of double-loop control, through prototype performance measurement indicates that the generator has the features of voltage waveform distortion rate is small and the voltage and frequency regulation rate is small, with engineering practicality.
