Crucial Torsional Modal Identify on Drive-Train in a Wind Turbine


Article Preview

The rotational frequency of large scale wind turbine is very low, so low order modal of drive-train in a horizontal-axis Wind turbine generator system (WTGS) needs special attention to avoid structural resonance. In this paper, with Lagrange’s equation, a three-mass drive-train dynamics of WTGS is modeled and analyzed. After comparing with the results by GHbladed4.1 and SIMPACK, we found that those results show little differences clearly. So the drive-train dynamics above is rational and the accurate analyses are fit to identify the crucial low order torsional modal of drive-train rapidly in WTGS. In addition, the anti-resonance frequency of the gear-train found by frequency response method can be very significant for vibration isolation of drive train in the wind turbine system.
