Wind - Today, nearly all wind generation is through the use of synchronous turbines. This means that the turbine speed is “in sync” with the grid in terms of frequency fluctuation. This is a necessity because frequency variation causes the grid connected to the turbine to overload and fail. Because of this wind speeds have been divided into two categories, VMI and VMA. VMI refers to all wind below a speed where it can be used. If the wind speed is below VMI the turbine must receive power from the grid to be synchronized. This means that the turbine is actually consuming power, rather than generating it. VMA refers to all wind above a speed where it can be used. If the wind speed is above VMA the turbine must be slowed down to achieve synchronization. This means that all wind above this speed is not used and is wasted. The Nextec Regeneration System controls the frequency variations so that asynchronous turbines can be used. This eliminates the need for a VMI and VMA value. In effect 50% more wind can be used because of this, compared to a conventional inverter. In addition to this, the Nextec system utilizes reactive energy to increase the output of the turbine. In this way the Nextec Regeneration System more that doubles the output of a synchronous turbine, and makes wind a viable replacement for fossil fuel based generation sources such as coal and oil.
