POWER SYSTEM FREQUENCY INERTIA FOR WIND TURBINES

摘要

The invention relates to a wind turbine system comprising: a wind turbine operable to supply wind power to an utility system; a synchronous generator coupled to the utility system; a grid measurement device arranged for measuring the current and power that is exchanged between the synchronous generator and the utility system; a controller for adjusting the output power of the wind turbine as a function of the power and current that is measured by the grid measurement device; and a means of communication between the grid measurement device, controller and/or the wind turbine, wherein the wind turbine is configured to provide current and power to the utility system as a function of the measured power and current of the grid measurement device.
