An object of the present invention is to provide a Wind Turbine Generation System that eliminates the necessity of switching to a circuit different from the one used during a normal power generation operation even when Power grid voltage sags. To accomplis...

Optimizes the operation and control of electric generators against events produced in the power grid, such as voltage dips or overvoltages, comprising the following steps: detecting that the DC bus voltage level (V bus ) (301) exceeds the maximum operating...
