农村建筑风光互补供暖系统的经济运行分析与研究

摘要

According to characteristics of rich wind energy resources and sufficient solar radiation in Qinhuangdao,designs a hybrid wind power-solar collector-electricity heating system,and builds the thermal balance model and economic model.Setting the system operation cycles of 10,15 and 20 years respectively,comprehensively optimizes the economic model with genetic algorithm from investment side.Comparing with coal-fired heating system,the results show that the multi-energy heating system with 15-year and 20-year operation cycles has better economic and social benefits,with a wide application prospect in rural residential buildings.%针对秦皇岛地区风力资源丰富、太阳辐射量充足的特点,设计了一种风电-太阳能集热-市电联合供暖系统,并建立了热平衡模型和经济模型.设置系统的寿命周期分别为10,15,20a,从投资的角度利用遗传算法对经济模型进行了全局优化.与传统燃煤供暖方式对比结果显示,该系统在15a和20a的运行周期内比传统供暖方式具有更好的经济效益和社会效益,在农村地区具有广阔的应用前景.
