自并励励磁同步发电机的暂态过程及强励分析

Analysis of Transient and Forced Excitation Ability for the Self-Excited Synchronous Generators

详细分析了采用自并励励磁方式的同步发电机在故障状态下的暂态过程及强励能力。其结果表明：同步发电机采用自并励励磁方式比采用其他励磁方式更安全、可靠；只要励磁系统设备选择、配置适当，即使在最严重的三相短路故障中，采用自并励励磁方式也能提供足够的强励能力。

The transient process and forced excitation ability for self-excited synchronous generators are analySed in detail. As a .result, it shows that self-excitation in synchronous generators is safer and more reliable than other excitations. Even if three phase short-circuit falts occur at the exit of high-voltage side of generators, enough forced excitation can still produced in self-excited generators.
