20KW-30KW Wind Turbine

Product summary:
1. 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.

Product name:
2kw-30kw pitch controlled wind turbine
(belongs to class wind turbine)
Product summary:
1. 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 12m/s, it will release the brake system, wind turbine restart to work. ASP makes nobody guard come true
2. Streamline design
Tail vane was designed by streamline, finding wind ability is higher about 30% than normal tail vane.
Product feature:
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, and 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 than rated wind speed.
(2) Stable running when wind speed is higher than rated wind speed
When the 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. 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.
4. Application field
Micro grid power station. On-grid system; wind and solar hybrid system; communication base station, frontier sentry, island and sight lighting system and so on.
