1MW Industrial Wind Turbine
from Winwind Ltd. Finland –
Product Review – Product Recommendation
The WinWind WWD-1 is a robust 1 MW turbine providing high yields especially at sites with low wind speeds. The WWD-1 is suitable for locations with challenging logistical conditions, size-limited areas, as well as inland sites.
The main advantages of the WWD:
-
30% less moving parts than traditional geared system
-
Loads bypass gears and generators
-
Low maintenance cost
-
Ideal for low wind speed sites
The Winwind WWD-1 is a 1 MW turbine suitable for areas with challenging logistical conditions (mountains, islands, etc.) and / or environmentally size-limited areas with rotor diameters of 56, 60 and 64 m. The 56 m diameter turbine is for higher wind speed sites (IEC wind class II) while the 60 and 64 m diameter turbines provide higher energy yields at lower wind speed sites.
WinWinD’s medium speed concept and the integrated power unit ensures the reliability of all WinWind wind turbines.

The WWD-1 is a highly reliable and robust wind turbine throughout its entire lifecycle. One of the WWD-1’s advantages is that the main bearing is transfering the rotor loads directly to the main casing of the supporting structure, keeping the whole drive train free from deformation. The integrated power unit, comprising the main bearing, planetary gearbox and permanent magnet synchronous generator, eliminates the unreliability of high-speed components.
The WWD-1 wind turbine maximizes energy capture especially at low wind speed sites. A very high efficiency is achieved by using an energy optimized rotor and a permanent magnet generator. The WinWind WWD-1 provides high productivity also in extreme demanding conditions and fulfills the most demanding grid code requirements. This is achieved through an advanced controler system and full conversion inverters.
WinWinD’s integrated power unit combines benefits from conventional drive train and direct drive systems. The key cuscustomer benefits are reliability, productivity and grid compatibility.
WinWind Ltd. Finland and Winwind Power Energy Private Limited, India also provide several services and options which are available for your wind park, including O&M and wind park control.
The WinWind WWD-1 can be installed as a single unit on- grid wind turbine system or combined as multi-units building an on-grid independent wind farm connection.
