Description
technical field [0001] The present application relates to the field of electrical technology, in particular to a method and device for obtaining a maximum power curve and a method and device for tracking maximum power. Background technique [0002] The wind generator power curve refers to the corresponding curve of the relationship between the active power output by the generator and the wind speed, and the maximum power curve is a curve formed by connecting the maximum power points of the power curves under different wind speeds. [0003] At present, the wind test method or drag test method is usually used to obtain a large number of test data of wind turbines, and then according to a large number of test data, the power curves under different wind speeds are fitted and generated, and then according to the power curves under different wind speeds, Determine the maximum power curve of the wind turbine. For example, using the wind tunnel test method, the wind turbine is plac...
