1. AH-20kW pitch controlled wind turbine advantage:
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 low 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.
2. High performance grid tied control&convert all-in-one system
With years of researching and practice,our company has developed a high performance grid tied control&convert all-in-one system suitable for the pitch controlled wind turbine, it help the wind turbine to run in a best status to ensure longer life and higher efficiency.
Performance characteristics
(1) Smaller size
This product is a integrated machine including on-grid controller and inverter. It adopts conversion technology. Comparing with the normal dimension, it is reduced by 50%.
(2) Higher integration
Except the controller and inverter 's function, it also include additional functions, such as remote monitor, brake, data record and so on.
(3) No dump load
We develop a special conversion technology according to our pitch controlled wind turbine, and we get rid of the dump load to make system more safety and reliable.
(4) Classic heat radiation structure, save energy
This product adopts nature wind heat-radiation technology. System can save 500kWh electricity per year
(5) High efficiency
The grid tied efficiency can come up to 97%.
(6) Redundancy protection design
Combining with system match and characteristics of each configuration, we develop multiple protections for this product. It makes sure the safety of wind turbine, controller and inverter, also ensure the system output efficiency.
3. Safety,steady,long running life!
3.1. 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.
3. 2 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(adjustable available), it will release the brake system, wind turbine restart to work. ASP makes nobody guard come true
4. Low running noise
Because of the outstanding permanent magnet generating technology and good blade aerodynamic characteristics, the noise level of the wind turbine has been greatly reduced, the level is no more than 65dB.
5.Easily construction and installation
Due to our modular production and assembly method, the user can install the wind turbine simply easily in the site without unnecessary trouble. We will offer professional construction and installation brochure.
6. Convenient maintaince
6.1 Remote monitoring and control service is available, you can learn real-time running status of the wind turbine and read the output power data effectively. The remote monitoring APP for mobile phone can be available soon.
6.2 The design of the hydraulic tower is advantageous to the regular maintenance work for the wind turbine.
6.3 Our ASP automatic safety protection system can realize "nobody on duty" that greatly reduce the workload and cost of the maintance. For convenience,the user can also switch the "Manual brake" or "Auto brake" button in the control box when maintance needed.
Classic case
ANE has exported AH-20kW grid tied type wind turbine to worldwide countries since 2009. There has been developed many region distributors in France,Italy etc. Up to now, the total installed capacity of the AH-20kW wind turbine has been more than 500 sets. Under the condition of that many countries has introduced preferential policies for grid tied subsidies, as a represent wind turbine of high efficiency,safety&rate of return, AH-20kW will definitely attract more and more investors from different countries.
