description	The invention belongs to the technical field of transformer safety control, and particularly relates to a transformer winding hot-spot temperature calculation method considering wind speed. According to the method, a common empirical formula for calculating the hot-spot temperature of the transformer winding is corrected by combining the influence characteristic of the wind speed of the external environment on the hot-spot temperature of the transformer winding, and a data set of the hot-spot temperature influenced by the wind speed of the external environment is determined by adopting a multi-physical field calculation or actual temperature rise test method; and finally, the optimal parameters of the empirical formula for calculating the hot-spot temperature of the transformer winding after improvement and correction are determined by adopting a particle swarm algorithm, so that the application range of the empirical formula for calculating the hot-spot temperature of the transformer winding is widened, and
