The invention discloses a wind power fluctuation component decomposer and a wind power output fluctuation characteristic assessment method. The method comprises the steps of inputting original wind speed data and fan characteristic data according to a set time interval; converting the input original wind speed data and fan characteristic data into wind power; decomposing the wind power into superposition of fluctuation components of a fluctuation period in different time level ranges; drawing an extremum difference frequency distribution histogram by taking an equal interval as a step length; forming a fluctuation component peak valley change value statistic index table; and comparing fluctuation characteristics of the different fluctuation components and assessing the influence of a wind power fluctuation characteristic on a power grid in combination with the properties of the influences of the different fluctuation components on the power grid. The decomposer and the method have the beneficial effects that multi-statistic-index and multi-timescale comprehensive assessment is carried out by regarding a wind power output as a multi-periodic change signal, taking a multi-timescale peak valley change quantity as a processing object and taking probability statistics as an analytic tool.
