摘　　要：针对单相自励感应发电机电压变化率大的问题,本文提出通过串联电容稳压的接线方式。利用对称分量法对三相感应电机自励单相发电运行进行了分析,导出了基本方程式和等效电路进而推出电机的性能计算公式,给出了电容的选取原则和方法。样机实验证明了分析的正确性。With the development and application of the source of regenerated energy and rapid growth of independent electric power stations, the self- excited power technology of induction generators is attracting more and more attention and has been researched considerably owing to its distinguishing feature. In view of large variation of output voltage of self- excited single phase induction generator, the paper presents an approach of self- regulation of voltage by series capacitor. The operation of self- excited single phase generation of three phase induction generator is analyzed by symmetrical component method, and the fundamental equations and equivalent circuit are derived. Then the formula for calculation of the generator performance and principle of selection of capacitors are given. The experiments of a sample generator verify the validity of the analysis.
