自并励发电机相间短路电流计算及保护配置和动作行为分析

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。

The out phase failure current of self-generating calculation,setting and action analysis of the protection

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 pro...
