Test stand for components of wind-power plant, has motor drive for pressurizing gearbox with rotational torque simulating wind force at specific rotation speed

摘要

The test stand (100) has gearbox (6), generator (2) and motor drive (10). The motor drive is provided for pressurizing the gearbox with rotational torque simulating wind force. The motor drive is operated at speed of 100 rpm. The motor drive has permanent magnet motor for transferring rotational torque without inserting the gear box directly to the countershaft of wind-power plant. An independent claim is included for method for checking components of wind-power plant.
