摘　　要：分析了风电场湍流强度对风电机组的影响,以1 650 kW变速变桨型风电机组为例,仿真分析了三种不同湍流强度特征值I15=0.18,0.16,0.14情况下的风电机组的极限载荷、疲劳载荷和性能,研究了其变化规律。结果表明,随着湍流强度的增加,风电机组的疲劳载荷和极限载荷都规律性地增加,其性能有一定程度的下降。Effect of turbulence intensity on wind turbines is analyzed in this paper. Simulation has been conducted for limit load, fatigue load and performance of wind turbines at three different turbulence intensity I15=0.18,0.16,0.14 by taking 1 650 kW variable speed wind turbine as an example. Simulation results show that with the turbulence intensity increasing, both fatigue and limit load of wind turbine will increase correspondingly and its performance will degrade to some extent.
