Abstract

With the rapid development of China's wind power industry, as well as the restriction of land, access system and other factors, the phenomenon of multi-wind field aggregation in the region is becoming more and more common. Firstly, in order to clarify the influence of wake clusters between adjacent wind farms on the power generation of wind farms, the measured data of three wind farms were used to simulate and calculate the power generation of downwind wind farms by using linear regression method. The simulation results show that the wake clusters between wind farms with a distance of 13 km on land have an impact on the power generation. Secondly, the influence of wake clusters on the load of wind turbine is analyzed using the FAST.Farm wind farm simulation tool. The simulation results show that the load of downwind fan in low-speed shaft, yaw bearing and other large components is significantly increased by the influence of wake clusters.
