轴承阻抗对双馈感应发电机转子绕组绝缘在线状态监测的影响

Doubly-fed induction generators (DFIGs) play a vital role in wind power generation, yet their rotor winding insulation is susceptible to failure due to high dv/dt voltage from rotor-side converters and mechanical stress under varying operating conditions. While existing methods primarily focus on fault diagnosis, capable of detecting short-circuit faults but lacking in prognostic capabilities, thi...
