Abstract: Wind power accurate prediction is important to the reasonable allocate use of wind power, power grid stability, commercial operation and decision service etc. This paper takes advantage of wind power prediction software at home and abroad, researches on the wind power prediction work flow, a WINd Power Prediction（WINPOP ） system which consisted of data acquisition, power prediction and precision analysis is designed. The paper introduces the designing idea, analyses the overall architecture and function module design， shows the main functions. At last, it gives the application example of the wind farms. The results of the test data indicate that WINPOP is reliable and the accuracy is above 85%. After using of the forecasting system, it can reduce rotating spare capacity, improve the utilization of wind power and ensure the safe and stable operation of power system.
