Global converted wind speed calculation method and system suitable for multiple wind power plants

The invention discloses a global converted wind speed calculation method and system suitable for multiple wind power plants, and belongs to the technical field of wind speed observation. The method comprises the following steps: acquiring historical power generation operation data of a plurality of wind power plants, and fitting a typical power curve of each wind power plant according to the wind power plant data; calculating the real-time inversion wind speed of each wind power plant based on the typical power curve and the real-time power; and according to the real-time inversion wind speed, establishing a global converted wind speed model of the plurality of wind power plants, and solving the global converted wind speed model to calculate the global converted wind speed of the plurality of wind power plants. According to the method, the global converted wind speed model is constructed to invert the wind speed of the single wind power plant, and the global converted wind speeds of the multiple wind power pl
