“…All of these uncertainties are considered in suitable weather conditions. In this paper, cold weather and rotor inertia are viewed as other sources of uncertainty in the wind turbine system [23,24]. If we place the wind turbine in Manjil, in the north of Iran, the turbine blades will freeze at the temperature below -10.3, the lowest measured temperature in the region between years 1989 and 2013.…”

Wind turbine is a complex nonlinear system that the exact model of this system is not available, so it can be represented as an uncertain system. Thus, the control of this system is an important topic. Most of methods that design controllers for wind turbines consider these systems in suitable weather condition. While many turbines work in cold weather condition, in this paper, wind turbine is considered in cold weather, and in ice on turbine blades are considered as model uncertainties. A robust controller is designed for the wind turbine, in order to control the pitch angle. Performance of the proposed controller is evaluated in a comparison study.

“…However, such areas are inherently susceptible to atmospheric icing events during colder periods of the year. Icing can deteriorate the power production of a wind turbine severely by reshaping the blade airfoil [3]. This phenomenon deviates the aerodynamic performance signi cantly [4,5].…”

Abstract. This study investigates the aerodynamic loads and energy losses of a typical 600 kW wind turbine with S816 airfoil blade under two di erent icing conditions. Three sections at di erent radial positions were considered to estimate the icing e ect along the blade. Ice accretion simulations in wet and dry regimes were carried out using the NASA LEWICE 3.2 computer program. The air ow simulations were performed with CFD method and SST k ! turbulence model. The results of these simulations, including streamlines, surface pressure, skin friction, lift, and drag coe cients, were inspected for both clean and iced airfoils. In the case of wet iced airfoil, a separation bubble was created in the leading edge due to a horn-shaped ice and then further downstream, the air ow was reattached. Ice-induced separation bubbles dominate the ow eld and aerodynamic performance of the wind turbine. In order to assess the production losses, the Blade Element Momentum (BEM) theory was used to calculate the power curves for clean and iced wind turbine blades. In the case of dry regime, deterioration of the performance is about 30% and, in another case, the turbine fails to produce any power at all.

“…At present, in China's southwest, central and southern and eastern wind power installed capacity increased significantly, however, due to the special geographical and climatic factors such as the low temperature, high humidity and high altitude, making these region wind turbine is more vulnerable to the icing phenomenon [3] . The icing on the blade surface not only severely restricts the mechanical and aerodynamic characteristics of the blade, but also seriously affects the output performance of the blade [4,5] . According to incomplete statistics, the loss of wind power generation by blade icing is about 1%~10%, while the loss in the harsh environment is as high as 20%~50% [6] , and the ice falls off from the blade will also cause a serious hidden danger of high altitude falling [7] .…”

Abstract. Aiming at the intelligent control strategy of the hot air blower de-icing technique for wind turbine blades was requirement. A high efficient and energy-economical intelligent control strategy was designed, the control strategy workflow and two intelligent modes were designed, namely pre-heating mode and de-icing mode. Through field de-icing tests, the results showed that the inner temperature of blade tip was around 30℃ when running at pre-heating mode, the blade tip surface temperature was 5℃, which was able to restrain ice formation and supply fundamental heat for de-icing mode. The inner temperature of cavity reached 60 ℃ for supplying enough heat to de-ice quickly when running at de-icing mode. Compared with the conventional de-icing method, the intelligent de-icing control strategy was saved 80% energy consumption in one icing period, which improved electrical production. The feasibility of the intelligent control strategy was proved and it benefited for further development of wind turbine industry under cold weather conditions.
