摘要
通过对叶片在不同工况下的受力分析,建立不同运行工况与风电机组叶片损伤量的关系,确定风电机组叶片损伤量与风电机组叶片寿命的关系;应用遗传-粒子群混合方法,以风电场内机组叶片延寿为优化目标,建立风电场内机组优化调度模型.将所提出的模型应用于某49.5MW风电场,对33台机组进行组合优化,算例结果表明在满足负荷的要求下,可减少启停机次数,延长机组寿命,验证该算法的可行性和有效性.
Abstract
The paper analyzes the force on the wind turbine blade in different conditions,and determines the relationship between the wind turbine blade damage value and different operation conditions,and the relationship between the wind turbine blade damage value and life of wind turbine blade.With life extension of wind turbine blades as the optimization objective,the optimal dispatch model is established by GA-PSO hybrid algorithm.To take a 49.5MW wind farm as example and meet the load requirements,it was reduced the number of start-stop times and extended the unit life.It is verified feasibility and reliability of the proposed optimal dispatching model.
