500KW Wind Turbine Investment Potential:  The Feed in Tariff for wind turbines of rated output between 100 - 500KW is 19.7p /KWh (Generation) + 3.1p /KWh (Export) in the first year, increasing with the rate of inflation.  

Technical Summary:

 Cost-Efficient

• Modern innovative design reduces turbine costs
• Reduced transportation and construction costs
• No need for expensive equipment to connect to the Grid 

 Durable and robust

• Excellent performance in strong and turbulent winds
• IEC class 1A certification (pending)

 Easy transport, installation and connection

• 3-5 metre wide roads, no upgrades or infrastructure typically required
• Two-bladed rotor and nacelle installed in one easy lift
• Synchronous generation allows cost effective connection to the grid

Two-bladed pitch teetering:

The Windflow two-bladed design uniquely allows the turbine blades to teeter on a hinge.  This teetering motion is linked to an asymmetric pitching mechanism of the turbine blades.  Uneven wind gusts are passively absorbed thus reducing the fatigue loads throughout the turbine.  This results in reductions in turbine weight and cost and an increase in turbine reliability.

Torque limiting gearbox:

With the aid of active pitch control, the turbine blades and hub deliver the gearbox with near-constant speed of rotation, via the low speed shaft.  The high speed shaft from the gearbox driving the synchronised synchronous generator requires a constant speed of rotation.  So, the small variations in hub speed (caused by potentially damaging wind gusts) are absorbed by a hydraulic pump on a second output from the gearbox.  The torque limiting gearbox is patented in several countries.

500 kW:

The 500kW Windflow turbine is a direct competitor to 3-bladed multi-mega watt turbines. On a per megawatt installed basis, the smaller, 500 kW turbine allows for easier transportation, more straight-forward installation and reduced environmental and visual impact considerations.  

Synchronous generator:

Due to the constant input from the Torque Limiting Gearbox, the Windflow turbine is able to utilise a synchronous generator, synchronised directly with the Grid without the aid of costly and unreliable power electronics.  As well as reducing costs and increasing reliability, this feature allows for easier connection.
