Study on On-line Monitoring of Generator's Rotor Circuit
Tian Hai-li · Large Electric Machine and Hydraulic Turbine · 1999
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.
