摘要
随着微机励磁调节器技术的不断提高,使得自并励发电机得到了广泛的应用。在机端、主变高压侧或单条线路(最小运行方式)上发生三相或两相短路故障时,自并励发电机与他励发电机短路电流有很大的不同,自并励发电机应配置什么保护、保护定值怎样整定及保护动作行为如何,继电保护人员都需有清楚的认识,文中用三个实际工程来加以说明。
With the improvement of the technology of microcomputer excitation regulator, self-excitaiton generators are widely used. The failure current of self-generating is very different from that of other generators during a three-phase or two-phase short-circuit failure whether the generator, the main transformer high side or a single line (minimum operating mode). Through the following three practical projects, this paper explains three questions: what protection should be used on self-generating, the action of that protection during failure, how to calculate the settings of that protection. Protection engineers should have a clear understanding on those ouestions.
