Abstract

The invention provides a meteorological threshold model construction method and a freezing map determination method and device.The meteorological threshold model construction method comprises the steps that freezing data, freezing meteorological data and geographic data of a plurality of reference point locations are obtained and recorded as reference freezing data, reference freezing meteorological data and reference geographic data respectively; the freezing data is used for representing whether the wind power plant at the corresponding point location is frozen in each time period, the freezing meteorological data is used for representing the meteorological data of the corresponding point location in the freezing time period, and the freezing time period is the freezing time period of the wind power plant at the corresponding point location; analyzing and processing the reference freezing meteorological data of each reference point location to obtain a reference meteorological threshold value of each reference point location; and determining a meteorological threshold model based on the reference meteorological thresholds and the reference geographic data of the plurality of reference point locations, the input parameters of the meteorological threshold model being geographic data, and the output parameters being meteorological thresholds. The method is helpful for providing a reliable basis for speculation of freezing data.
