风光互补设施温室的设计及能耗分析

Design and Energy Consumption Analysis of Wind-Solar Complementary Facility Greenhouse

为了探讨风、光互补发电在设施农业领域的可行性,选择宁夏风光资源较为丰富的中部干旱带,在已有基础上研究设计了一种能够利用风、光互补发电系统供电的日光温棚,并计算分析了风力发电、光伏发电等相关指标。研究得出:宁夏中部地区风光互补性良好,适合应用风、光互补发电系统,合理配置下,该发电系统每年发电量约为15481.3 kW·h,能够在春、夏、秋三季满足日常温棚常规用电需求,而且发电量有盈余,如果条件允许则能够实现并网发电。在冬季由于夜间温度较低,温棚需要采用电暖风机加热,导致用电量骤增,需要外接电源或应用其他供暖方式。

In order to explore the feasibility of wind-solar hybrid power generation in the field of facility agriculture,the central arid zone in Ningxia,which is rich in wind-solar resources,was selected as test area.Based on the existing foundation,a kind of solar greenhouse that can be powered by wind-solar hybrid power generation system is designed,and related indicators such as wind power generation and photovoltaic power generation were calculated and analyzed.The research shows that the wind and solar complementarity is good in the central part of Ningxia,which is suitable for the application of wind and solar hybrid power generation system.Under reasonable configuration,the annual power generation capacity of this power generation system is about 15481.3 kW⋅h,which can meet the routine use of daily greenhouses in spring,summer and autumn.Moreover,there is a surplus in power generation,and grid-connected power generation can be realized if conditions permit.In winter,due to the low temperature at night,the greenhouse needs to be heated by electric heaters,resulting in a sudden increase in power consumption,requiring an external power supply or other heating methods.
