Fault Analysis of Inter-Turn Short Circuit in Rotor Winding of Generator
Chao Zhang · Electric Machines and Control Application · 2011
The inter-turn short circuit in rotor winding of generator will cause the field current to increase and reactive power output to decrease.It will also introduce the aggravation of vibration.Severe damage will be caused to the safe operation of the generator if such faults were not handled properly in a timely manner.In order to settle this question,fault analysis of inter-turn short circuit in rotor wingding must be solved.Based on the multi-loop theory,the math model of some generator was established,all of the inductances were calculated too.The validity and effectiveness of this method were verified by comparing simulation and experiment results,which could calculate electrical quantities accurately such as currents.This method provids good basis for fault analysis of inter-turn short circuit in rotor wingding.
