In this study, the operation of the turbine blade pitch controller is examined under two different blade icing conditions and various wind speeds: a step rising wind, a wind gust, and a turbulent wind. The results obtained are compared with no blade icing condition. Employing the MS Bladed Model, the blade pitch controller is run for a 5 MW turbine. Under the step rising wind speed, considered blade icing conditions are observed to disturb the transient response of the controller, i.e., the rotor speed, but not the steady-state response. Depending on the amount of ice accretion, controller transient performance decreases differently at different wind speeds. Under the wind gust, a different transient rotor speed response trend is observed from that obtained under the step rising wind speed. Except for the steady-state, different rotor speed transient responses are seen, relying on icing conditions. Under the turbulent wind, the effects of different blade icing conditions are seen in the rotor speed response during sudden changes in wind speed. As blade icing increases, the rotor speed response starts deviating from the response in no icing case. Depending on blade icing conditions, the controller sets the blade pitch angles to different values under all these wind speeds.
