中文摘要: 储能系统是能源利用与转化的重要组成部分，在新能源消纳方面起着重要的作用，可有效实现电网的"削峰填谷"。为此，设计了3种不同保温层厚度和3种不同长高比（L/H）的蓄热体，采用实验方法研究了保温层厚度和蓄热体结构参数对固体蓄热装置放热特性的影响。结果表明：蓄热体与环境的温差是影响蓄热装置放热速率的主要因素；不同L/H的蓄热体放热速率明显不同，L/H=0.500时的放热速率最小，L/H=0.300时的次之，L/H=0.885时的最大。
Abstract:Energy storage system is an important part of energy utilization and transformation.It plays an important role in new energy consumption,which can effectively realize the shifting peaks and filling valleys of the power grid.Therefore,three types of heat storage bodies with different thickness of thermal insulation layer and three different length-height ratios (L/H) are designed.The effects of the thickness of thermal insulation layer and structural parameters of thermal accumulators on the heat release characteristics of solid heat accumulators are studied experimentally.The results show that the temperature difference between the heat storage body and the environment is the main factor affecting the heat release rate of the heat storage device.The heat release rate of different L/H regenerators is obviously different,the heat release at the rate of L/H=0.500 is the smallest,the heat release at the rate of L/H=0.300 is the second,and the heat release at the rate of L/H=0.885 is the largest.
