Zusammenfassung:The invention relates to a wind electricity active power extremum detection method comprising the following steps: reading a result of wind electricity climbing detection, classifying tops and bottoms in climbing into a maximum set and a minimum set respectively, and replacing the two extremum sets with better extremums within an extremum optimization time threshold scope; adjusting the two extremum sets according to the definition of extremum; supplementing new extremums; comparing adjacent same-direction extremums, and selecting an optimal extremum; optimizing the two extremum sets; and inserting an opposite extremum between two adjacent same-direction extremums. The invention further relates to a device which comprises an extremum primary selection module, an extremum optimization module, an extremum supplement module, an extremum comparison and screening module, an extremum optimization processing module and an extremum insertion module. Extremums in wind electricity power data can be detected quickly and
