Abstract EN
The purpose of this paper is to explore the effect of the baseline control system (BCS) on the fragility of large-scale wind turbine when seismic and wind actions are considered simultaneously.
The BCS is used to control the power output by regulating rotor speed and blade-pitch angle in real time.
In this study, the fragility analysis was performed and compared between two models using different peak ground acceleration, wind speeds, and specified critical levels.
The fragility curves with different wind conditions are obtained using the multiple stripe analysis (MSA) method.
The calculation results show that the probability of exceedance specified critical level increases as the wind speed increases in model 1 without considering BCS, while does not have an obvious change in the below-rated wind speed range and has a significant decrease in the above-rated wind speed range in model 2 with considering BCS.
The comparison depicts that if the BCS is neglected, the fragility of large-scale wind turbine will be underestimated in around the cut-in wind speed range and overestimated in the over-rated wind speed range.
It is concluded that the BCS has a great effect on the fragility especially within the operating conditions when the rated wind speed is exceeded, and it should be considered when estimating the fragility of wind turbine subjected to the interaction of seismic and aerodynamic loads.
