Abstract | The invention discloses a power grid near-real-time rainfall estimation method, system and device and a storage medium. The method comprises the steps that real-time spectral information of a stationary satellite is acquired and preprocessed to generate real-time feature data; inputting the real-time feature data into a pre-constructed rainfall estimation model to obtain an estimated value of near real-time rainfall; wherein the construction of the rainfall estimation model comprises the following steps: acquiring historical spectral information and historical meteorological data of a stationary satellite and each meteorological station at each moment in a preset time period; preprocessing the historical spectral information to generate historical feature data at each moment; performing space-time matching on the historical feature data and the historical meteorological data to obtain a data pair set; dividing the data pair set to generate a training set, a verification set and a test set; constructing a Ligh |
