3 MW wind turbine
WWD-3 is a 3 MW utility class turbine that offers a reduced energy production cost and is suitable for both land based and near-shore installations. With the option of a 100 m rotor diameter, it can provide higher energy yields at lower wind speed sites, while the 90 m rotor diameter option is for higher wind speed sites (IEC wind class II).
WinWinD's medium speed concept and integrated power unit ensure the reliability of our wind turbines. Our 3 MW turbines are type certified.
What is WWD-3?
WWD-3 is a pitch regulated upwind wind turbine with active yaw and three-blade rotor. The turbine consist of three main parts:
- Rotor - 3 blades and hub with electrical pitch control
- Integrated power unit - Two row tapered roller bearing, planetary gear and variable speed generator with permanent magnets
- Nacelle - Frequency converter, transformer and accessories
High reliability through Redundancy
High reliability is in-built to the WWD-3 turbine, with two 1.5 MW converters run independently in parallel, which means that if one converter fails, the turbine will still be operational with the remaining converter. The converters cooling systems and auxiliaries are also independent and redundant. Converter losses are minimised and the thermal load is reduced as the turbine only operates with one converter during low winds when there is only partial generation.
WWD Advantages
-
30% less moving parts than traditional geared system
-
Loads bypass gears and generators
-
Low maintenance cost

Options
WWD-3 turbines come as standard with WinController which controls an individual turbine and minimizes the loads and maximizes the energy output. WWD-3 is equipped with this as a standard feature.
As the penetration of wind energy and the size of wind parks increase, grid operators and owners are demanding stricter control of individual turbines and whole wind parks. In order to meet these requirements, the following options are available.
|
WinGrid |
WinWinD turbines can provide the required active or reactive power to the grid and can be adjusted continuously without steps. |
|
WinFlick |
The flicker effect from the blades in certain sectors can be avoided with this option |
|
WinParkControl |
This provides active and reactive power controls on the Point of Common Coupling (PCC). WinParkControl analyses the local weather conditions and individual turbine conditions in order to optimize the park energy output and fulfill the park and/or grid operator requirements. |
|
WinSCADA |
WinSCADA is a graphical web based user interface that is developed for remote monitoring of power plants. |
| WinSwitchGear |
Different project specific switch gear configurations are available. |
|
WinDataPackage |
WinWinD can tailor a customer specified data package according to their requirements. |
|
WinRemoteRedundance |
Offering a fail-safe redundant route for the turbine control system. |
|
WinSilence |
Offers reduced noise mode levels for noise sensitive areas. |
|
WinIce |
Ice prevention system for blades to avoid the build up of ice on the surface |
|
WinStorm |
Offers controlled cut-out in stormy weather conditions |
|
WinHMI |
A user friendly, graphical interface which operates in real time can be included in the control system of the turbine. |
|
WinForecast |
Based on up to date local weather conditions, this provides accurate production forecasts. |
