Abstract
A wind farm is presented. The wind farm includes a plurality of wind turbine stations, where each wind turbine station includes a wind turbine and a generator sub-system. The generator sub-system includes a doubly-fed induction generator configured to generate an alternating current voltage and a wind turbine station power converter. The wind farm further includes a power collection sub-system that includes a power bus and a sub-station power converter. The wind farm also includes a control system configured to determine a wind speed metric, estimate a corresponding frequency metric, calculate a desirable frequency based on the wind speed metric and frequency compensation ranges of the wind turbine station power converters, and generate and communicate control commands to the sub-station power converter based on the desirable frequency to allow the sub-station power converter to update a line frequency of a power bus voltage based on the desirable frequency.
