风电场尾流分布计算及场内优化控制方法
Wake Distribution Calculation and Optimization Control Method for Wind Farms
摘要
Abstract
For existing wind farms,one goal of the wind farm optimization control is to reduce the wake effects and improve the overall power output.The coupling relationship between the variation of state parameters,power output and the wake distribution of wind turbines are analyzed.The calculation method of the intersection area between the wake and the wind rotor is presented.And a wake superposition model among multiple turbines is developed.A wake distribution calculation method is proposed for calculating the wind speed at each turbine location,which can be used to calculate the wind speed distribution of wind farms accurately and efficiently under varying wind speed and direction.Based on the wake distribution calculation model,the power output of overall wind farm is maximized with the axial induction factor of individual wind turbine as the adjustable parameter.The particle swarm optimization (PSO) algorithm is chosen as the optimization searching algorithm,and the wind farm optimal control model is developed.Wind farm Horns Rev in Denmark is selected as example,and the calculation results show that the wind farm wake distribution calculation method is able to accurately calculate the wake distribution,and the wind farm optimization control method will improve the overall power output.关键词
