同步发电机自并激励磁系统逆变过程分析

摘要

The paper presents the rectification and inversion process of static excitation system for synchronous generator with proposing a method of making the bridge rectifiers of excitation transformer and the thyristor equivalent to the load impedance during the inversion, the analysis on de-excitation process during the inversion, and the calculation of inversion time combining with circuits analysis. The application of the analysis will be verified via the actual project cases.%本文介绍了同步发电机自并激励磁系统整流、逆变过程.结合电路分析,提出了逆变时将励磁变、可控硅整流桥等效为负载阻抗方法,分析逆变灭磁过程和计算逆变时间,结合实际工程案例进行了验证.
