METHOD AND APPARATUS FOR POWERING A WIND TURBINE

摘要

The invention related to a method for powering a wind turbine following a grid voltage failures. After the presence of grid power has been once again detected, the Grid Connection Control System (GCCS) is then powered by an Uninterruptable Power Supply (UPS). The GCCS closes the grid switch that had been powering the power protection equipment. The SAI used by this powering method has low operating autonomy, remains disconnected during the power grid failure and begins to operate when grid power is reestablished without the need for any auxiliary power.
