We have a patented technology that allows new or existing wind turbines to produce up to 663% additional electricity generating power below 3 metres per second and above 25 metres per second when existing wind turbines cannot operate. The following video illustrates this point.
All current wind turbines use single generators and can only produce electricity in a confined operating window.
The majority of commercial wind turbines cannot produce electricity below 3 metres per second (10.8 Kilometers per hour).
Current handmade propeller blades cannot handle wind speeds higher than circa 72 Kilometers per hour (44.73 miles per hour), as they are not balanced. As such the propellers must have a brake applied to stop them turning entirely so they are not damaged and therefore they no longer produce electricity.
Our unique “thinking outside the box” approach to this problem has resulted in a totally new design in wind turbine power generation.
The NNP turbine has a series of different sized generators linked to differentials that allow the blades to rotate from wind speeds as low as 0.3 metres per second through to 25 metres per second and above automatically engaging and disengaging the generators in sequence to maximise the wind force as it increases and decreases 24 hours a day.
By utilising multiple different sized generators our turbine can operate in low and high wind speeds that are out of the operating window of current single generator turbines.
The other benefit of the multiple generator NNP turbine design is the stresses and loadings are spread through multiple generators rather than a single one in current turbines. This has potentially big savings in down time and maintenance costs, especially relevant in offshore wind farms.
The reports supporting our design theory have been produced independently by the WECC at the University of Strathclyde who are a leading worldwide authority in wind turbine design and operation.
These can be downloaded below together with examples of the increased power generation produced in a simulation of an NNP turbine equipped Vestas 1.8MW V100 turbine which increased power generation to 2.2MW. We also have a simulation of the expected power generation increases in a 5.5MW turbine.
