problems in wind turbine system coupled one mass drive train with PMSG?

i am designing this system but i got issue in output of drive train couldn't match the rated speed. what will be the reason?

Hi Oliyad,

I understand that the output of the drive train could not match the rated speed when trying to simulate the wind turbine system coupled one mass drive train with PMSG.

You can try the below steps to resolve the issue:

• Make sure the Drive Train Parameters such as inertia, damping, and stiffness parameters of the drive train are accurately set as these parameters significantly affect the dynamic response and steady-state behaviour.
• Make sure the Wind Turbine Parameters such as wind speed, turbine rotor diameter, and power coefficient (Cp) curve are correct, as Incorrect values can lead to mismatched operational conditions.
• Ensure that the PMSG control system (e.g. vector control) is correctly tuned to maintain the desired speed and power output.
• Consider mechanical losses in the drive train, such as friction and windage losses as these can reduce the output speed if not accounted for.
