励磁系统对同步发电机的影响可以从几个方面反映出来?

发布日期:2019-07-10 作者: 点击:

转子的励磁绕组用直流电激励,产生接近正弦波分布的磁场(称为转子磁场),其有效磁场通量与固定电枢绕组相交。当转子旋转时,转子的磁场在同一旋转中每转一周旋转。磁线顺序切断定子各相绕组,并在定子绕组中感应交流电势。同步发电机励磁系统由定子和转子两部分组成。发电机励磁系统可以发送有功和无功功率。转子磁场的强度直接影响定子绕组的电压。因此,转子电流应通过调节发电机端电压或调节发电机的无功功率来调节。

一、励磁系统提供同步发电机励磁绕组的直流电源。励磁系统对同步发电机的影响可以从以下几个方面反映出来。

三、电机采用电容相移相复合励磁装置

次级线圈安装在发电机定子上,用于特殊励磁。发电机定子线圈作为整流后的励磁电流,通过励磁调节器将励磁机感应的交流整流到直流,作为励磁电流馈入发电机。
