The invention relates to a method and a device for extracting meteorological features influencing power generation power in a new energy power generation system, computer equipment, a storage medium and a computer program product. The method comprises: acquiring an initial meteorological feature set; adopting a random forest algorithm to screen meteorological features in the initial meteorological feature set to obtain a first meteorological feature set; based on correlation analysis, performing meteorological feature screening on the first meteorological feature set to obtain a second meteorological feature set; and adopting a recursive feature elimination method to screen meteorological features in the second meteorological feature set to obtain a target meteorological feature set. According to the whole scheme, meteorological features are preliminarily extracted according to a random forest algorithm, on the basis of the preliminarily extracted features, correlation analysis is performed on the meteorologi
