Vertical wind turbine generator(VAWTs)are a type of wind turbine where the main rotor shaft is set vertically and the main components are located at the base of the turbine. VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. They are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width.
Lowest cut-in wind speed
1 m/s for power production
No noise, no vibrations
(sound level< 25 dB at 7 m/s from 10 m distance)
Adaptable for hybrid solutions
With solar and other sources of energy
Permanent power supply
From wind/solar and continuous battery charging
Technically advanced Maglev generator
No mechanical friction
Best price-performance ratio All weather resistant
(rain, ice, heat, salt, sand)
Independent of wind direction
Suitable for roof fixation
Safety for people and nature
|1. Leading centrifugal pitch controlled technology world-wide.|
|(1) Exactly regulation|
Information input source of pitch controlled mechanism is wind rotor rotating speed. System regulation is more stable, reliable and quick response and so on.
(2) Softness regulation
Impact caused by wind speed becoming will be decreased through the pitch controlled mechanism. Regulation soft, failure rate low
(3) Longer service life
System adopts mechanical part, floating connection, smaller fraction losses, less failure sources, better environment adaptability, Longer Service life.
|2. High efficiency, 30% electricity more than normal wind turbine|
|(1) Lower start up wind speed|
Pitch controlled wind turbine blades have the best start up angle, can be started up with 2m/s wind speed. Best wind power availability when the wind speed is lower then rated wind speed.
(2) Stable running when wind speed is higher than rated wind speed
When then wind speed is higher than rated wind speed, secondary regulation starts up to make sure system have a stable output power. Lower start up wind speed, then increase the rotating speed, then have a stable output power with a higher wind speed to make sure there is a 30% more electricity output.
|3. Dual protection system|
|(1) Double degree pitch controlled technology|
Wind turbine adopts pitch controlled regulation, more easier to start up and increase rotating speed with smaller wind speed; Below rated wind speed, system have a higher efficiency with best TSR; Over rated wind speed, rotating speed is never over speed with minus blade angle.
(2) ASP System (Automatic safety protection system)
ASP system, our patent product is unique protection system in China. It can control the wind turbine to run or stop by testing the environment wind speed and system working voltage. When the environment wind speed or system voltage is over the set value, it will shut up the wind turbine. When the wind speed is lower than 25m/s, it will release the brake system, wind turbine restart to work. ASP makes nobody guard come true
|4. Streamline design|
|Tail vane was designed by streamline, finding wind ability is higher about 30% than normal tail vane.|
|5. Easy installation|
|(1) Easy to installation without any heavy equipment likes crane, save installation cost.|
(2) Carry and installation are not limited by landform, especially for mountain area and island
(3) Tilt-up tower, easy to install and maintenance.
