摘　　要：风力发电系统是包含风力机、发电机等多子系统的复杂系统,其整体性能研究尚未开展。为评估风电系统整体性能,这里通过分析子系统间能量传递关系,构建系统整体的能量传递函数模型,利用Matlab/Simulink软件对系统传递函数进行建模仿真,将模型仿真结果与搭建的垂直轴风电系统试验平台试验结果对比分析的方式研究能量转换过程中系统性能的变化。分析结果表明,系统的仿真功率与试验功率的相对误差为3.7%,仿真效率与试验效率的相对误差为4.3%,且曲线变化趋势同步。验证了风电系统能量传递函数模型能够预测系统整体的能量转换性能和输出特性,为风电系统部件的选型与匹配提供了参考价值。Wind power generation system is a complex system including wind turbine,generator and other subsystems,and its overall performance has not been studied.In order to evaluate the overall performance of the wind power system,the energy transfer Junction model of the overall system is constructed by analyzing the energy transfer relationship between subsystems in this paper.Matlab/Simulink software was used to model and simulate the transfer function of the system,and simulation results were compared with test results of the vertical axis wind power system test platform,so as to study the change of system performance in the process of energy conversion.The results show that the relative error between simulation power and test power of system is 3.7%,the relative error between simulation efficiency and test efficiency is 4.3%,and curve trend is synchronized.It is verified that the energy transfer function model of the wind power system can predict the overall energy corwersion peiformance and output characteristics of the system,which provides reference valuefor the selection and matching of wind power system components.
