The invention provides a wind power output characteristic analysis method based on WAMS data. The method includes the following steps that wind power output characteristics are determined; the wind power output characteristics are analyzed; a wind power plant group is defined and subjected to statistics analysis. Through the wind power output characteristic analysis method based on the WAMS data, the wind power output characteristics are quantified, and therefore technical references can be provided for analyzing influences of access of a large-scale wind power plant on a power grid. Meanwhile, lots of wind power operation monitoring data are accumulated and analyzed, schedule operation staff can be assisted in mastering a wind power operation law, and analysis bases are provided for absorbing wind power more scientifically and reasonably and guaranteeing safe and stable operation of the power grid.
