The invention provides a method for evaluating the power generation performance of a wind turbine generator. The method comprises the following steps: (1) selecting a to-be-evaluated wind turbine generator; (2) acquiring the electric quantity in a reference evaluation period and the electric quantity in an optimization evaluation period; (3) carrying out electric quantity improvement effect evaluation; (4) acquiring a reference evaluation period fault rate and an optimization evaluation period fault rate; and (5) carrying out fault rate change evaluation. According to the method, a double-unit mode (the optimization unit and the reference unit) is adopted to evaluate the power generation increasing effect and the failure rate change, the wind direction and wind speed change is considered, the two methods are adopted to obtain the result, the lower value is selected as the final power increasing ratio value, and good accuracy can be achieved. 本发明提供了一种风电机组发电性能评估方法，所述方法包括(1)选取待评估风电机组；(2)获取基准评估期电量和优化评估期电量；(3)进行电量
