4. Advanced technology
4A. 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.
Benefits
• Mechanical design, safe and reliable
• Precise control:
Upper limit of RPM is controlled within 10rpm, precise management
• Multiple protection for key components, precise machining
4B. 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. RENERGY wind turbine became a significant of safety. Traditional brake including dump load (electronic brake), manual brake or non variable pitch brake.
• Since 2010, the first ABS system was designed. Now ABS system has been applied in variable pitch wind turbines widely, it became a last step safety protection

6. Noise level
noise level report
1. Test conditions:
a. The measurement is made in 10 meters of height, which is a Danish law for noise measuring of windmills.
b. The mill has “soft” surfaces around it, like earth and grass.
c. The microphone is placed 17 meters behind the mill, seen from the direction of the wind, with a hard surface underneath it.
2. Test results:
