针对鱼蟹稻田飞虫捕食装置的离网型户外供能需求的问题,着重研究该装置的供能系统方案。基于户外供能合理性要求,采用小型风力发电机和太阳能电池板自主互补发电来进行能源供应;对小型风力发电机和太阳能电池板分别进行Matlab/Simulink建模,着重对叶轮的风能利用系数、叶尖速比和桨距角的相关性进行量化分析,利用单因素分析法对太阳能电池板进行分析;在桨距角确定的条件下,适当取值叶尖速比,能够获得最大风能利用系数。同时,在不同温度和辐射的条件下,太阳能电池板能够取得功率曲线的峰值,为风光互补的最大功率获取提供理论上的支持。针对离网型风光互补系统能源的合理化利用,提出混合供能的能量管理策略,符合该装置的供能需求,对户外同类型装置供能设计提供一定的参考。

Aiming at the problem of the off-grid outdoor energy supply of the fish crab paddy field flying insect predator,the research is focused on the energy supply system of the device.Based on the rationality requirements of outdoor energy supply,small wind turbines and solar panels are used for autonomous energy supply;Matlab/Simulink modeling is used for small wind turbines and solar panels,focusing on the wind energy utilization factor of the impeller,The correlation between the blade tip speed ratio and the pitch angle is quantified,and the solar panel is analyzed by using a single factor analysis method.Under the conditions of the determined pitch angle,the appropriate value of the blade tip speed ratio can obtain the maximum wind energy utilization coefficient.At the same time,under different temperature and radiation conditions,the solar panel can achieve the peak of the power curve,providing theoretical support for the maximum power acquisition of wind and solar complementary.Aiming at the rational use of energy in off-grid wind-solar complementary systems,an energy management strategy for hybrid energy supply is proposed,which meets the energy demand of the device,and provides a certain reference for the energy supply design of outdoor similar devices.
