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.
