March 2003 - From the idea to the product
The idea
Can electricity from wind power plants operating under variable-speed conditions be supplied in such a way that synchronous generators without frequency converters like those used in conventional power plants be used?
Compared to the present solutions for wind power plants, the result would be a considerably better quality grid and compliance with all requirements regarding power fed into the grid.
The idea: to apply to the wind power industry the proven principle of the Vorecon unit with its variable-speed planetary gear set, which at this point in time had already been employed successfully over 100 times in power plants as well as gas and oil applications, thereby developing a reliable solution that provides excellent grid quality.
The solution
It quickly became clear that the hydrodynamic variable-speed planetary gear set might also be suitable for wind power plants. With the difference in this case that variable input speeds would have to be converted into constant output speeds. In other words, a mirror image of the power flow associated with the basic design of the Vorecon was needed. |

July 2003 - The concept
Starting with this idea, a team of two individuals investigated conceptually all essential operational aspects of a wind power plant during the year 2003. Through extensive computer modeling, the concept proved functional! |
