20090099702 | SYSTEM AND METHOD FOR OPTIMIZING WAKE INTERACTION BETWEEN WIND TURBINES - A system and method to increase the overall power output of a windpark during conditions when the wake created by an upstream turbine effects the power production of a downstream turbine. Minimizing the wake effects created by an upstream turbine on a downstream turbine increases the net power produced by both the upstream and downstream turbines. The invention is an implementation of an algorithm to determine the controller settings of one or more upstream turbines to increase total energy capture of the turbines in the windpark. The algorithm also reduces the fatigue loads on the downstream turbines by reducing the turbulence created by the wake effects of the upstream turbine. | 04-16-2009 |
