Improved Efficiency and Production at low wind speeds– Advanced Aerodynamic Design and highly efficient aero profiles (blade root design) enable maximum production at low wind speeds.Technological Highlights:
- Maximum Output under any wind speed : Variable Pitch and Speed System with Hydraulic pitch and Double Fed Induction Generator (DFIG) with speed and power controlled by Insulated Gate Bipolar Transistor (IGBT) converters and electronic PMW (Pulse Width Modulation)
- Reduced Transmission Losses : Dry Type transformer, specially engineered for wind applications, placed inside Nacelle, reduces Low Voltage transmission losses usually found in taller turbines
* For last 4 months, after stabilization period of 60 Days
Higher Co-efficient of Power (Cp) in low wind speeds:
