针对固态电热储能系统的热力计算进行研究,根据内置电阻式蓄热体结构特点提出一种基于加热、蓄热、取热、换热4部分的流固耦合热力计算方法,并对加热丝、蓄热体结构、换热系统、变频风机等参数进行具体计算。通过实际案例对系统进行设计参数敏感性分析与工况校核计算,并提取实验数据,验证热力计算方法的正确性。
In this paper,the thermodynamic calculation of the solid state electric energy storage system is studied.According to the structure characteristics of the built-in resistance type regenerator,this paper proposes thermodynamic calculation method for fluid solid coupling that based on the four part of calculation of heating,heat storage,taking the heat and heat transfer. Meanwhile,the parameters of heating wire,regenerator structure,heat transfer system and variable frequency blower are calculated concretely. The sensitive analysis of the design parameters and the checking calculation of the working conditions are conducted through practical cases. Moreover,the experimental data are extracted to verify the correctness of the thermodynamic calculation method.
