In this study, the operation of the turbine blade pitch controller isexamined under two different blade icing conditions and various wind speeds:a step rising wind, a wind gust, and a turbulent wind. The results obtained arecompared with no blade icing condition. Employing the MS Bladed Model, theblade 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 ofthe controller, i.e., the rotor speed, but not the steady-state response. Depending onthe amount of ice accretion, controller transient performance decreases differently atdifferent wind speeds. Under the wind gust, a different transient rotor speed responsetrend is observed from that obtained under the step rising wind speed. Except forthe steady-state, different rotor speed transient responses are seen, relying on icingconditions. Under the turbulent wind, the effects of different blade icing conditionsare seen in the rotor speed response during sudden changes in wind speed. As bladeicing increases, the rotor speed response starts deviating from the response in noicing case. Depending on blade icing conditions, the controller sets the blade pitchangles to different values under all these wind speeds.
