A study on an evaluation of dynamic captureability under high turbulence intensity

涡轮机系统入口气流的波动是导致功率性能下降的重要因素。这种波动是由于风涡轮机现场的气象和复杂地形造成的。风力机涡轮机现场分布较多，风力机的国际标准IEC 61400 -12因其强湍流特性而无法适应。此外，小型风力涡轮机系统具有更复杂的问题，这些问题不仅涉及对流速变化的响应，而且涉及对流动畸变的响应。在本研究中，估计功率性能下的高湍流强度网站和一个动态捕获能力的小型风力涡轮机的估计。

A fluctuation of the inlet flow to a wind turbine system is an important factor that causes decrease of the power performance. The fluctuation is caused by meteorology on the wind turbine site and also the complex terrain. There are many wind turbine site which the international standard for wind turbines: IEC61400-12 cannot adapt because of such strong turbulence. Furthermore small wind turbine system has more complex problems which are concerned with a response to not only flow speed change but also flow distortion. In the present study, a estimation of power performance under high turbulence intensity site and a estimation of a dynamic captureability of small wind turbine are shown.
