This paper investigates the impact of the control system bandwidth on the decision of incipient faults in doubly fed induction generators used in wind turbines. In this application the rotor is supplied by a static converter for the control of active and reactive power flows from the generator to the electrical grid. The impact of the closed loop control system cannot be neglected when the detection of asymmetries in the machine are based on the signature analysis of electrical variables.

Abstract
This paper investigates the impact of the control system bandwidth on the decision of incipient faults in doubly fed induction generators used in wind turbines. In this application the rotor is supplied by a static converter for the control of active and reactive power flows from the generator to the electrical grid. The impact of the closed loop control system cannot be neglected when the detection of asymmetries in the machine are based on the signature analysis of electrical variables.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
