摘要
本文介绍了发电机转子部件缺陷时对发电机的影响和危害，针对转子绕组提出一种以建立数学模型的方法来预测在一定工况下发电机转子绕组回路电阻变化区间，并以此为判据，判断回路发生故障与否；同时针对阻尼绕组提出了用多回路法计算阻尼条电流，并提出一种数据传递方式实施对阻尼绕组的监测。通过两者的综合以实现对转子回路的在线监测。
In this paper,Influence and harm against generator is introduced when defection of generator's rotor occurs. A mathematics model is brought forward to predict range of resistor variety of generator rotor winding circuit in a sure working condition and the range is used to determine whether the circuit is defective. Be directed to damp winding damp bar is calculated though multi circuit method,and a way to transfer data is offence to monitor damping winding. Thus the on-line monitoring of circuit is realized.
