Abstract
It is of great importance to study the characteristics of wind power output for the healthy and secure & stable of power grid. Based on the actual operating data, the probability distribution of the power fluctuations of the wind farm in Hainanand the variation of wind power annual, seasonal, daily active output is analyzed. The study showed thatHainanProvincehas obvious seasonal variation of wind power output characteristics, higher levels of output of the year generally in winter or summer, spring and autumn to contribute small. The average wind power output will contribute to “low day and high night”, with certain peaking capacity. Shorter time scales, changes in the wind power to smaller amount, not to bring too much impact on system operation, while a long time fluctuations affect the scheduling and running on the grid.

Wind power annual utilization hours can evaluate the level of efficiency in the use of the wind farm, the level of annual utilization hours reflect the relative size of the level of wind speed from the other side in different years
Summary
With the growing energy and environmental problems, the development of new energy has been a concern around the globe. China has a vast coastline of wind energy resources are widely distributed and relatively rich areas are mainly concentrated in the southeast coast and nearby islands and the northern. The new energy is one of the pillar industries in recent years to focus on supporting the development of Hainan, Hainan wind power has been rapid development. As of the end of June this year, Hainan new energy installed capacity of 249.5 MW wind power project to dominate. Only by the statistics and analysis of a large number of actual data, can we get the variation of the wind power in particular areas. Further with the probability distribution method, the fluctuations of wind power are quantitative analyzed, as well as the impact on Hainan power grid
