| 摘 要： | 在发电机启、停过程中，由于发电机调速器抽动或操作不当，会造成发电机低频过激磁，而励磁系统的V／F限制不能可靠动作。文章对产生发电机低频过励的原因进行了分析，提出改造发电机逆变灭磁二次回路的思路，通过改造有效地防止了发电机过激磁。

| Abstract: | In the startup and stop process of the generator,it's always occurred the low-frequency overexcitation because of the twitch and improper operation of the governor,thus cause the V/F limitation of the excitation system can not be reliable acted.The paper makes an analysis of the overexcitation reason,and proposes the thread of transforming the secondary circuit inversion field suppression of the generator,through the transformation,the overexcitation phenomenon of the generator has been effectively avoided. |
