GE Energy introduces WindINERTIA. WindINERTIA joins the GE suite of grid integration products designed to give wind turbines the capability to meet transmission reliability standards similar to those demanded of thermal generators.
GE's WindINERTIA feature allows wind turbines to provide an inertial response for large, short-duration frequency deviations through a control system upgrade, to enhance grid reliability and operation. By utilizing the mechanical inertia of the turbine rotor, GE's WindINERTIA control enables an operating turbine to increase its power output by 5-10% of its rated turbine power, over a wide range of wind speeds. The duration of the power increase is several seconds and benefits the grid by allowing time for other non-wind power generation assets to increase power production during large under-frequency events. The WindINERTIA control is available for GE's 1.5-megawatt wind turbine.
