Study On The Wind Collecting Performance Of Parabolic Mask For Concentrated Wind And Concentrated Light Power Generation

Existing renewable energy power generation systems often utilize solar or wind energy in a separate form,resulting in a waste of resources in many climate conditions where wind and solar energy coexist.Concentrated photovoltaic power generation technology and concentrated wind power generation technology are relatively effective forms of energy utilization for solar energy and wind energy respectively.In order to improve the comprehensive utilization of energy,based on the scene using electricity into an organic whole,design a kind of parabolic concentrated wind power generation system,and in the middle of the concentrator photovoltaic power generation systems of parabolic concentrator do an opening used for installation of wind turbine impeller,parabolic gather the wind into an organic whole,implementation of the comprehensive utilization of solar energy and wind energy.The performance of a parabolic windshield with concentrated wind and light is studied.A parabolic wind collector with an inlet diameter of 1500mm,a focal length of 600mm and a central opening diameter of 400mm is designed,and its modeling and numerical calculation are carried out.The experimental device was constructed for wind accumulation experiment,and the wind speed on the axis of the wind accumulation hood was obtained.Compared with the corresponding numerical simulation results,the two trends were consistent,with a maximum error of 9.7%.Within an acceptable range,the parabolic wind accumulation hood constructed was correct.The maximum daily power generation of parabolic windshield with concentrated wind and light is analyzed.Based on Weibull model to calculate the wind frequency distribution of the specific circumstances,design different parabolic non-uniform flow field structure of wind turbine blades,and sliding grid technology has carried on the numerical calculation,the wind power and wind energy utilization coefficient,according to the wind frequency distribution was calculated under different parabolic focal length and the opening diameter together the power of the wind power generation.According to the local solar radiation in Nanning,Guangxi,the concentrated photovoltaic power under different parabolic structure is calculated.The daily operation arrangement of the parabolic wind-gathering and concentrating power generation system was designed according to the solar radiation and wind conditions,and the maximum daily generating capacity was calculated to be 3958.45w · h.The focal length of the parabolic structure with the maximum daily generating capacity was 700mm,and the opening radius was 600mm.The daily power generation of the parabolic wind-gathering and concentrating power generation system is compared with that of the separate concentrating photovoltaic power generation system and the wind power generation system,and the excellent performance of the parabolic wind-gathering and concentrating power generation system is verified.
