2.Core technology:
1. Variable pitch
Variable pitch wind turbine is a patented product and pioneer in wind turbine industry. The self-developed centrifugal pitch controlled mechanism of Wind turbine adjusts blade pitch following wind rotor rotating speed, and keep wind turbine at rated rotating speed. The wind turbine has a stable output power and safe running and is maintenance free.
1)Mechanical design, safe and reliable
2)Precise control: Upper limit of RPM is controlled within 10rpm, precise management.
3)Multiple protection for key components, precise machining.
2. ABS -Aerodynamic brake system
ABS system includes pitch regulation mechanism, active brake, controller, and other parts. System detect wind speed, voltage, current and other electrical parameters to determine wind turbine running or shut down.
ABS system is the first time for small wind turbine to realize automatic brake function. Traditional brake including dump load (electronic brake), manual brake and non variable pitch brake.
3. Intelligent control
It's an innovated intelligent electrical system, adopting the best wind turbine control technology and combing variable pitch wind turbine characteristics. Main hardware are from best international supplier, have stable running capability and strong anti-interference ability. The software adopts redundancy control strategy to ensure system running safely and reliably. System has strong extendibility; it can match with all kinds of famous brand inverter and remote monitor module. It meets client's requirement of one-stop service.
1) Intelligent protection
2)Remote monitoring
3)Active yawing
