摘　　要：风热机组是风能利用的一种有效形式,可以将风能直接转化为热能。文章介绍了风热机组的基本组成,构建了一套包括风能转换、发电系统和热泵系统的风热机组仿真模型,分析了风热机组的制热性能。研究了不同参数对机组制热性能的影响及其变化规律,总结了最大制热效率获取方法。计算结果表明,来流风速不影响机组制热性能系数,但影响热泵系统供热量。随着热泵系统蒸发温度增加和冷凝温度降低,制热性能系数增加。蒸发温度和冷凝温度差值越大,机组供热越大。本研究结果可以为风热机组优化控制提供依据。Wind turbine heating system is an effective form of wind energy utilization,which can directly convert wind energy into heat energy.The basic composition of wind turbine heating system was introduced,a simulation model of wind turbine heating system including wind energy conversion,power generation system and heat pump systems was constructed,and the heating performance of the wind turbine heating system was analyzed.The effects of different parameters on the heating performance and their variation rules were studied,and the method for obtaining the maximum heating efficiency was summarized.The calculation results show that the incoming wind velocity does not affect the heating performance coefficient,but affects the heating capacity of the heat pump system.As the evaporation temperature of the heat pump system increases and the condensation temperature decreases,the coefficient of heating performance increases.The larger the difference between the evaporation temperature and the condensation temperature,the greater the heat capacity of the wind turbine heating system.The research content of this paper can provide help for the optimal control of wind turbine heating system.
