摘  要:
在传统的风光互补发电系统的基础上,建立基于直流母线的系统模型,利用Matlab分别搭建风力发电机、光伏阵列及直流斩波器模型.根据风能和太阳能发电系统最大功率跟踪控制基本原理,运用变步长扰动方法控制脉冲发生器的占空比,实现最大功率点的跟踪控制.稳态模型的建立可以评估预测所设计系统的各种性能.为建立实验平台和示范工程奠定基础.

摘  要:
On the basis of traditional wind-solar hybrid generation system, a model of single-phase based on DC bus is established, and the models of wind turbine, solar arrays and DC chopper are built respectively with Matlab. According to the basic principles of maximum power point tracking in the wind-solar power system, to control the duty cycle of the pulse generator and achieve to track the maximum power point by using the perturbation method of variable step size. The establishment of the steady-state model can be assessed to predict the design system performance, and laid the foundation for the establishment of experimental platforms and demonstration project.
