摘要: For modern large wind farms, it is interesting to design an efficient diagnosis system oriented turbine generators based on doubly-fed induction machine (DFIM). Intensive research effort has been focused the signature analysis predict or detect electrical and mechanical faults in machines. Different signals can be used, voltage, current, stray flux. In case of generators, considering that both control are accessible, for diagnostic purposes, there additional possibilities, example use converter modulating voltages. this paper, a complete analyzed by suitable simulations experimentations deeply study fault influence identify best procedure perform predictive maintenance
