Double-fed Induction Generator Rotor Fault Diagnosis Considering Control Strategies of Rotor-side Converters
摘要
Abstract
Condition monitoring and fault diagnosis of rotor windings of double fed induction generators (DFIG) can detect the fault timely and reduce operations and maintenance costs for wind turbines effectively.From the simulation,the impact on extraction of fault characteristic signals from different control strategies of the rotor-side converter is found,and an experimental platform is established.Also through analyzing the experimental data,the correctness of simulation results is validated.First,a double fed induction generator's rotor fault model is established by using PSCAD software,where SVPWM vector control and hysteresis current vector control are applied in the control strategies of the rotor-side converter.From the simulation analysis,the diagnostic scope of characteristic signals including the rotor current and the rotor voltage is derived.In addition,the experimental platform of rotor fault diagnosis is built in the laboratory considering the change of generator's speed and loads.Finally,the characteristic signals are analyzed to validate the impact of control strategies of the rotor-side converter.关键词
