“…Roberge et al [72] analyzed several undisclosed wind farms in eastern Canada based on Meteorological Condition Monitoring Stations (MCMS), pan-tilt-zoom cameras, and visual observations. The study recommended that icing events be defined using a 1 • C threshold of the lowest temperature within two hours prior to each timestamp.…”

The development and utilization of clean energy is becoming more extensive, and wind power generation is one of the key points of this. Occasionally, wind turbines are faced with various extreme environmental impacts such as icing, lightning strikes and so on. In particular, the icing of wind turbines increases icing–wind loads, and results in a reduced power output. And blades broken down lead to large-area shutdown accidents caused by high-speed rotating, which seriously affects the reliability and equipment safety of wind power generation. Relevant institutions and researchers at home and abroad have carried out a lot of research on this. This paper summarizes the formation and influencing factors of wind turbine icing, the influence of icing on wind power generation, and defense technologies. First, it introduces the formation conditions and mechanisms of icing in wind farm regions and the relationship between meteorological and climatic characteristics and icing, and analyzes the key influence factors on icing. Then, the impact of icing on wind turbines is explained from the aspects of mechanical operation, the power curve, jeopardies and economic benefits. And then the monitoring and safety status of wind turbines icing is analyzed, which involves collecting the relevant research on anti-de-icing in wind power generation, introducing various anti/de-icing technologies, and analyzing the principle of icing defense. Finally, this paper summarizes wind turbine icing and its defense technologies, and puts forward the future research direction based on the existing problems of wind power generation icing.

“…Ice formation on the blades causes a decrease in lift and at the same time an increase in drag force, resulting in reduced power output from the wind turbine [8][9]. In addition, the ice accretion on the wind turbine structures can lead to partial or complete mechanical destruction, errors in measurements, and a threat to human health and life due to ice falling from the blades [10][11]. Consequently, the IOP Publishing doi:10.1088/1755-1315/1154/1/012079 2 operation of wind turbines in northern weather conditions requires additional technical solutions and in-depth knowledge of the ice formation process.…”

The paper investigates the flow behavior near the NACA 64-618 airfoil profile of the blade tip section of a wind turbine for electric power production after a short icing event. The flow simulation considering the rotation speed of the wind turbine blade is performed to assess the effect of icing on the aerodynamic characteristics. Degradation of aerodynamic characteristics affects the electrical energy production of the wind turbine. The aerodynamic lift and drag coefficients are calculated for different angles of attack. The flow velocity fields near the airfoil are analyzed. The pressure coefficient distributions along the profile surface are obtained. The points of flow stall and changes of aerodynamic characteristics at different angles of attack are determined.
