    摘要:

    针对中小型风电测试场的用途及风能资源的有效利用,提出了机位 “梯形”和“分散”两种布置方案,基于WAsP软件进行两种方案下的年发电量和尾流损失计算,得出“分散布置”方案下年发电量、尾流损失均优于“梯形布置”。根据该地区盛行风向和第二主风向的特点,进行了两种不同方案的数值模拟,利用CFD数值模拟方法深入剖析尾流损失的具体原因,得出了机位之间尾流速度相互影响的关系,加入第三风向对机位作出调整,并最终得到了最优布置方案,将风电测试场的年发电量提高到了142.323 MWh,风力机的尾流损失减少到了0.219 %。

    Abstract:

    For the use of small and medium-sized wind power test sites and the effective use of wind energy resources, provided two layout plans: “trapezoidal layout” and “distributed layout”. Based on WAsP to simulate the annual generating capacity and wake losses for both plans. It is concluded that the annual generating capacity and wake loss of the “distributed layout” are better than the “trapezoidal layout”. Based on the characteristics of the prevailing wind direction and the second main wind direction in the area, carried out numerical simulation of two different plans. Using CFD numerical simulation method to deeply analyze the specific reasons of wake loss, obtained the relationship between the wake velocity interaction of the position, and the third wind direction is added to adjust the position, and finally got the optimal layout. The annual generating capacity of the wind power test site is increased to 142.323 MWh, and the wake loss of the wind turbine is reduced to 0.219%.
