基于全风场功率输出的风力机控制策略研究
Research on the Control Strategies of the Wind Turbine Based on the Total Output Powers of the Global Wind Farm
摘要
Abstract
To decrease the wake effect of upstream wind turbines and realize the global optimization of the wind farm,simulations of nine yaw and fifteen tilt control methods with the upstream turbine were carried out based on an actuator line method with OpenFOAM.In all control methods,according to comparisons of total output powers of the wind farm,fluid field profiles at the wind turbine hub height and wind farm vertical sections through rotors center,the flow mechanism of the influence on downstream turbines with different control strategies of wake deviation was investigated.The results show that,changing the wake direction with different control methods,although the output power of the upstream wind turbine declines mildly,the total output powers of the wind farm increase significantly due to the output power rise of the downstream wind turbine.Both strategies of wake deviation can optimize the wind farm globally and each has an optimal angle,but with yaw prior to tilt and the plus tilt prior to the minus.关键词
