Our VAWT Turbine
Wind turbines are clean power harvesters
converting the kinetic energy of the wind into
electric power by rotating about their either
vertical (VAWT) or horizontal axis (HAWT)
The VAWT developed by Green ITEC is
custom made to suit the installation location
wind regimes even at low wind speeds.
These vertical axis systems outperform the
traditional large HAWT’s in urban regions with
turbulent wind profiles due to their ability to
run smoothly, independently from the wind
The most common turbines manufactured are
the 25, 50, and 100 kW. One of the most
common turbines, the 50 kW has a main rotor
shaft is set transverse to the wind while the
main components are located at the base of
the turbine. This arrangement allows the
generator and gearbox to be located close to
the ground, facilitating service and repair.
VAWTs do not need to be pointed into the
wind, which removes the need for wind-sensing
and orientation mechanisms. In addition,
different sizes can be placed in one system
architecture to reach the combination needed.
The primary application of wind turbines is to generate energy using the wind.
Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
Though the details of the aerodynamics depend very much on the topology, some fundamental concepts apply to all turbines. Every topology has a maximum power for a given flow, and some topologies are better than others. The method used to extract power has a strong influence on this. In general, all turbines may be classified
as either lift-based or drag-based, the former being more efficient. The difference between these groups is the aerodynamic force that is used to extract the energy. The most common topology is the horizontal-axis wind turbine. It is a lift-based wind turbine with very good performance. Accordingly, it is a popular choice for commercial applications and much research has been applied to this turbine. Despite being a popular lift-based alternative in the latter part of the 20th century, the Darrieus wind turbine is rarely used today. The Savonius wind turbine is the most common drag type turbine. Despite its low efficiency, it remains in use because of its robustness and simplicity to build and maintain.
Starting from the experience gained in the field of
production systems from renewable sources connected
to the grid, Elpower has developed the family of PCS
CLEANI- SLAND, for the management of the grid
connected or off grid storage systems.
In the Industrial and Commercial scale in which
green itec operates, essentially two types of storage
systems are provided.
