摘　　要：针对载热流体直接蓄热型蓄热系统,建立蓄热系统动态模型与燃煤机组模型,并在此基础上分析系统在充热和放热模式下的导热油流量变化规律与蓄热罐中的导热油体积变化规律。以南京地区辐射条件加热600 MW亚临界火电机组给水为例,计算结果表明该模型具有借鉴意义。Aiming at direct heat storage system for heat transfer fluid （HTF）, the dynamic model of heat storage system and the model of coal-fired units were established to analyze the flow variation of heat transfer oil in the system under heat charge and heat release mode and the volume change of heat transfer oil in heat storage tank. Taking solar radiation condition in Nanjing area heating the feed water of 600 MW subcritical thermal power generation unit as an example, the calculation results show that the model has a reference value .
