Features, Specifications & Advantages
- Double Fed Induction Generator (DFIG)- increased power output & reduced reactive losses.
- Superior power curves – one of the lowest cut-in wind speeds and rated wind speeds resulting in higher power generation for low wind regime sites of India.
- Patented integral drive train incorporating rotor shaft and gearbox as a single unit with less turbine weight and less moving parts, resulting in ease of O & M.
- One of the largest rotor diameters in its class – resulting in higher swept area and consequently higher power output.
- Advanced electronic control systems resulting in higher machine uptime. Hub height of 80/92/113 meters – to capture better wind speeds.
- Technological enhancements such as using capacitors instead of battery banks which increases machine up time.
All electrical components are sourced from reputed global suppliers to ensure high efficiency and reliability of turbines.
A very strong, energetic and experienced team comprising experts across all relevant fields.
