Wind turbine Electric equipment

AH-20kW Pitch controlled wind turbine

★Leading technology——Intelligent control, the system can be expandable.

? ? ? ? 1. Combine the world excellent wind control technology and self-developed pitch controlled technology

2. The hardware adopts international famous brand, the software adopts redundant control strategy.

3. It can be well compatible with various well-known brand converters and remote modules

★High safety——unattended continuous operation all the time

1. The rotate speed is regulated by pitch controlled mechanism all the time,the turbine can operate steadily even in worse wind condition.

2. More than ten redundant control strategies make sure the system safety and stability in all climate.

★Generate more power——Pitch controlled regulation,high efficiency, more than 30% output

1. Above rated wind speed, blade pitch angle will be passive regulated to keep full-power output.

2. Large working wind speed range（3-25m/s）.
