2. Technology character
1. Nose-up pitch yawing: When the wind speed is over rated speed, the wind wheel will be up under high wind pressure to reduce the wind pressure, keeping control rotating speed function. To compare with the traditional yawing wind turbine, nose-up pitch yawing could not only keep the stable output of max power, but also could reduce the gyroscopic force, increase of service life.
2 Double rudder plate structure: The wind turbine could find breeze wind, more efficient, more accurate.
3 Pure automatically mechanical cast loose: No transmission slip ring, low failure rate, low cost.
(3) Longer service life
System adopts mechanical part, floating connection, smaller fraction losses, less failure sources, better environment adaptability, Longer Service life.
b. 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.
d. Streamline design
Tail vane was designed by streamline, finding wind ability is higher about 30% than normal tail vane.
e. 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.
3. Application field
Micro net power station. on-grid system; wind and solar hybrid system; GSM base station, frontier sentry, island and sight lighting system and so on.
