Advantages and Disadvantages of Vertical Axis Wind Turbines

There are two main types of wind turbines: horizontal axis and vertical axis wind turbines (VAWTs). VAWTs have a unique design that offers several benefits, but they also have some limitations. If you are considering a wind power solution, ELEGE provides high-quality options to meet your needs.

Advantages of Vertical Axis Wind Turbines

• Stable Performance with Optimized Design

  • The straight blades and triangular dual-support structure make the turbine more stable.
  • The blades are arranged in a circular shape, reducing stress on the central support.
  • The gearbox and other parts are placed close to the ground, making maintenance easier.

• Low Noise, Ideal for Various Environments

  • The blade design follows the principles of an airplane wing, reducing air resistance and noise.
  • With horizontal rotation, the turbine operates quietly, making it suitable for urban areas.

• No Yaw System Needed, Simple Structure

  • The blades rotate parallel to the ground and capture wind from all directions.
  • Unlike horizontal turbines, VAWTs don’t need a yaw system, reducing mechanical wear.

• Strong Wind Resistance for Harsh Conditions

  • The horizontal rotation and dual-support design lower wind pressure on the turbine.
  • It can withstand typhoon-level winds up to 45m/s, making it more reliable in extreme weather.

• Lower Blade Material Costs

  • The blades only need to handle wind pressure and centrifugal force, reducing material requirements.
  • You can use common materials, which lowers production and maintenance costs.

• Wider Wind Speed Range

  • VAWTs can achieve higher speeds than horizontal turbines and remain stable in strong winds.
  • With proper control strategies, they can handle wind speeds up to 60m/s, improving efficiency.

Disadvantages of Vertical Axis Wind Turbines

• Lower Energy Efficiency

  • Some blade positions create negative torque, reducing energy output.

• Vibration Issues Affect Stability

  • Large turbines may experience vibrations, requiring additional support structures.

• Unstable Power Output

  • Wind speeds change frequently, causing fluctuations in power generation.
  • To connect to the grid, energy storage or adjustment systems are needed.
