GWP 47 is an active stall regulated wind turbine with a rotor diameter of 47 meter. The 21 meter long blades can be feathered to obtain optimal operational conditions at both low and high wind speeds.

The GWP 47 combines the best from both the stall and the pitch regulated wind turbines: It has the same regulation options as the pitch regulated turbine, but by using the stall properties of the blades, the large load and power fluctuations that are typical for a pitch regulated machine are avoided. The controller is developed to self optimize the blade angle for wind speeds below rated power. Due to its blade regulation it is possible to make a lot smoother cut-in to the grid at start-up, and cut-out to shut down. This will give less noise on the grid in these situations and at the same time extends the lifetime of the transmission and electrical system of the turbine.

Durability begins with a quality product. Lagerwey's newest generation of direct drive turbines is ready for the future and is challenging the old concepts in many aspects.

Lagerwey's long experience and innovative mind regarding direct drive technology has resulted in an optimal next generation turbine called the GWP82-2000kW. Reducing the amount of components and design simplicity are essential drivers in making durable quality.

The turbine has a permanent magnet generator with excellent efficiency in partial and full load. Together with a full power converter we are able to deliver a clean, grid friendly power even during worst case circumstances.

Due to the variable speed principle, the turbine is the best choice when conditions get rough. An advanced electrical pitch system reduces the loads and guarantees maximum energy capture. The only moving part with a high load cycle is the main bearing into which Lagerwey has deliberately engineered a comfortable safety margin regarding wear and loads. The automatic lubrication system is closely monitored and is very accessible for maintenance.

The GWP82-2000kW has a hollow main shaft for direct internal access to the hub. This makes the design light together with high stiffness to withstand the loads. All service can be done comfortably from the inside of the turbine. The generator is closed from outside influences and has an efficient passive cooling system that makes it withstand the most severe environments (dust, coastal operation etc.).

Transportation and installation costs have become major costs in the multi megawatt turbine class. Our concept with ready to fit assembly modules ensures low installation costs and requires minimal crane capacity. The turbine can be erected with a 500 tonne mobile crane.

The GWP82-2000kW energy capture is very high, especially where it matters, in partial load. In partial load the turbine outperforms the existing drive train concepts by far.

Design margins and low installation and maintenance costs make the turbine a low risk investment and combined with the excellent energy capture allows for an attractive return on investment. This is the turbine of choice for your projects.
