Case Study | Wind Turbine Anti-Icing: Smart Aerial Solution for Safer Winter Operations

A major energy enterprise operating large-scale wind farms across southwestern China faced critical challenges with turbine icing during winter months. In high-altitude regions with low temperatures and high humidity, freezing rain leads to significant ice accumulation on wind turbine blades. This results in increased structural fatigue, reduced equipment lifespan, lower energy output, and serious safety concerns for the wind farm.

To ensure continued operation in freezing conditions, regular anti-icing measures are essential. However, traditional de-icing methods—such as manually dislodging ice with tools on elevated platforms—are inefficient, labor-intensive, and pose high safety risks. In search of a scalable, intelligent solution, the company aimed to prevent icing proactively and improve operational reliability across its sites.

High-altitude operations requiring strict personnel and equipment safety measures

Large-scale anti-icing demand with high standards for coverage, consistency, and efficiency

Harsh terrain and variable weather conditions complicating deployment and execution

The company evaluated a wide range of intelligent maintenance solutions, including wall-climbing robots and various UAV platforms. However, many systems lacked sufficient environmental adaptability, had complex deployment requirements, or involved high operational costs with limited safety assurance.

After extensive technical comparison, the company selected the P2 (A30) High-Pressure Aerial Cleaning System, mounted on a heavy-lift drone platform such as the DJI FC30. Designed for aerial operation, this system enabled the automated spraying of anti-icing fluid across turbine blades. The engineering team also customized the spray nozzles to optimize fluid distribution based on the blade surface and weather conditions.

Unlike conventional cleaning or robotic systems, the P2 (A30) is specifically engineered for high-altitude industrial applications, providing stable, safe, and efficient spraying of water, anti-icing fluid, or cleaning agents from the air.

Safety and Stability

Integrated with remote-control functionality and laser-based distance measurement, the P2 (A30) removes the need for manual high-altitude work. Its balanced structure improves aerial stability and effectively counters spray recoil during operation.

Flexible Operation

The system supports multi-angle adjustments while hovering, ensuring full coverage of complex surfaces and hard-to-reach areas. This reduces the need for drone repositioning, improving both operational efficiency and coverage consistency.

Intelligent Precision

With built-in path planning and surface recognition algorithms, the system can intelligently adapt to turbine blade geometry for consistent and accurate spraying. Modular nozzle design allows for the application of various fluids depending on the task and surface material.

Efficient Deployment

Featuring a compact foldable structure, the system is easy to transport and deploy in remote mountainous regions. Its high-capacity tank system allows for quick refilling and extended operation without downtime.

The deployment of the P2 (A30) aerial system significantly improved the efficiency and safety of wind turbine anti-icing operations, delivering the following outcomes:

Achieved accurate, uniform spraying of anti-icing fluid across turbine blades

Eliminated the need for human presence in high-risk environments

Ensured turbine surface protection with non-contact, intelligent spraying

Improved overall operational efficiency and reduced labor costs

Enabled rapid, scalable deployment across multiple wind farms

Enhanced winter energy output and reduced turbine failure rates
