Pendular Wind Turbines

PRINCIPAL CHARACTERISTICS

The unique design of the ADES wind turbine includes three passive mechanical systems: a swivelling single-blade rotor, a pendulum power train and a self-steering nacelle. The design compensates, accumulates and reinstates wind speed variations, preventing them from affecting the evenness of generator rotation and subsequently diminishing structural overload and power peaks caused by wind gusts.

BENEFITS

By supplying high-quality energy with less structural loads, these turbines can be connected in new parks, in areas with weak networks and in parallel with other energy sources, as well as be used in the repowering of wind farms, taking advantage of the existing infrastructures.

WHY A NEW DESIGN?

It is a well-known fact that wind energy has been used from early times, especially as an aid to navigation. At present, modern wind turbines transform this energy into electricity and transfer it to the grid.
However, their lacks of continuity and, in particular, its lack of evenness in intensity and direction have negative effects for both the turbines and the stability of the electrical system to which they are connected.

Current wind turbine technology, the design of which is based on the Danish model (three windward blades), solves these problems by sizing the structures to resist these loads and governing the machines with active regulation and control servosystems that are capable of overcoming natural phenomena to limits recommended by safety and supported by available expense.

And SO?

Therefore, one of the main goals of our design is to eliminate these stiffnesses by using systems that can compensate, accumulate and reinstate these variations, preventing them from affecting the evenness of generator rotation and subsequently attenuating power peaks and structural overload.

Building machines that suffer less fatigue, including mechanisms that provide them with a higher degree of freedom by using the wind force that makes the machine suffer to protect it by accommodating to new balanced operational positions (passive systems), is the philosophy behind our designs.

APPLICATIONS OF THE TECHNOLOGY

With all these qualities derived from their simplicity, reduced maintenance and the quality of power supplied, these turbines are adequate for installation in grids and/or locations where turbines could not be used previously. They are also suitable for working alone or in parallel with other renewable energy sources such as:

• Isolated generation, microgrids.
  

• Supply of constant mechanical energy for specific applications (pumping-desalination).
  

• Areas with turbulent wind flows
  

• Wind farms repowering
  

• New wind farms.
