摘　　要：大型压缩空气储能电站一般使用地下洞穴作为储气设施,地下洞穴的准确容积不易测量,因此通过储气容积来计算储能电量存在困难。使用少量的运行数据构建起了压缩空气储能电站储能电量与储气压力的对应关系,并使用后续运行数据对不同高温换热介质温度和不同低温换热介质温度下储能电量进行修正,得到相对准确的储能电量计算方法。Large-scale compressed-air energy storage(CAES)power stations generally use underground caves as gas storage facilities,and the accurate volume of underground caves is not easy to measure,so it is difficult to calculate the quantity of stored electricity by the gas storage volume.In view of this issue,the paper employs a small amount of operation data to construct the correspondence between the energy storage and the gas storage pressure of the compressed-air energy storage power station,and then uses the subsequent operation data to correct the energy storage capacity under the temperature of different high-temperature heat exchange medium and different low-temperature heat exchange medium,so as to obtain a relatively accurate calculation method for the quantity of the stored electricity.
