摘要 阻尼绕组对发电机短路电流值大小起着决定性的影响 ,本文就阻尼绕组对同步发电机整流系统直流侧短路时的最大短路电流及对基本波形的影响分别进行了分析计算和试验验证 ,得出了无阻尼绕组同步发电机整流系统直流侧短路电流值较有阻尼绕组同步发电机有明显下降 ;阻尼绕组具有改善同步发电机整流系统交直流侧电压波形的作用 ,去掉阻尼绕组使得交流电压波形谐波含量增大 ,波形畸变加剧 ;q绕组对改善电压波形效果明显 ,可以弥补减弱阻尼引起的对电压波形的损害。 The damping winding has a great influence upon the short circuit current value. In this paper the influence of the damping winding upon the maximum short circuit current and the basic wave form are analyzed, calculated and tested respectively, when the short circuit of the rectifying system of the synchronous generator happens. The result is that the short circuit current value of a generator without a damping winding is obviously reduced as compared with a generator with a damping winding. The damping winding is of a function of improving the voltage wave form of the rectifying system of a generator. If no damping winding, the harmonic wave of AC voltage wave form will increase and wave form deforms seriously. The q winding has an apparent effect of improving the voltage wave form, and can compensate the damage to the voltage wave form caused by a weakened damping.
