The integrity of wind power output data is very important to the utilization of wind energy.Using any one of the adjacent turbine data，persistence strategy，average interpolation strategy and standard power curve strategy，one is enabled to complete the missing wind power data，but each strategy has its own advantages and disadvantages.On the basis of multiple single data completing strategies，the adaptive neuro-fuzzy inference system（ANFIS）model is proposed，and the fuzzy inference algorithm is adopted to complete the missing data，till optimization of the final results.It is shown by simulation calculation of the wind data measured that the average relative error is reduced and the accuracy of data completing is improved.
