摘　　要：由于电抗分流式水力发电机的励磁系统比较简单，在并列运行中存在许多问题．随着电子技术的发展，在发电机励磁系统中已推广应用了电子电路实现检测和控制，但对小型水力发电机的旧式励磁系统改造应用有限．本文简述了电抗分流式发电机励磁系统改造．介绍一套简单的可控硅励磁装置，用这套装置使小型水力发电机在并列运行时，具有外特性稳定、无功调节度宽的特点．There are many problems in concatenation operation because the magnetizing system of reactance flow dividing water power generator is simple. As the electronic technique develops, the electronic circuit checking and control in generator magnetizing system have been publiced and applied, but the improvement and apptiance of old magnetizing system on small water power generator is limited. This paper introduces simply the improvement of reactance flow dividing generator's magnetizing system. It introducas a simple controlled silicon magnetizing device. The small water power generator have the stablity of external characteristic and the wide idle work adjust degree when the device is used in concatenation operation.
