摘要：

An offshore 5.5 MW horizontal axis wind turbine（HAWT）is taken as an example，the impact of wind abandonment and power limitation on the power and load of a single wind turbine is analyzed based on historical SCADA data，combined with time-averaged and instantaneous high-resolution data. On this basis，it is discussed that power limitation can produce fatigue damage to important structural components of the HAWT，and suggestions are made to prevent the occurrence of power limitation phenomenon. The results of the investigation show that power limitation reduces the wind turbine power generation efficiency and torque，and increases the torque applied unit power. It slows down the trend of decreasing power coefficient and torque coefficient with increasing wind speed. Power limiting increases the pitch angle of the blades and also increases the temperature and torque fluctuation of the pitch motor，the blade angle under large power limit is approximately 3 times of that without power limitation，with significant power limiting increasing the temperature by 14% compared to unlimiting power and increasing the torque fluctuation by more than 30%. In addition，power limiting indirectly reduces the temperature of the gearbox and generator. © 2024 Science Press. All rights reserved.
