摘　　要：文章依托某2×350 MW燃煤机组,通过配套建设补热型压缩空气储能系统,对压缩空气储能工艺系统、参数选择、补热热源选择、燃煤机组改造方案等方面进行技术研究和分析。研究认为,在地质条件合适的燃煤机组附近,通过采用绝热压缩+热水储热+人工硐室的工艺方案,建设一定容量的压缩空气储能机组,可实现对燃煤机组的深调。燃煤机组可向压缩空气储能系统提供补热热源、冷却水、除盐水等资源,补热型系统的电电转化效率略高于非补热型。Based on a 2×350 MW coal-fired unit,this paper studies and analyzes the compressed air energy storage process system,parameter selection,heat source selection for supplementary heating,coal fired unit reconstruction scheme and so on through supporting the construction of supplementary heating compressed air energy storage system.It is considered that by adopting the process scheme of adiabatic compression,hot water storage,artificial cavern near the coal-fired unit with suitable geological conditions,a compressed air energy storage unit with a certain capacity can be built,which can realize the deep adjustment and peak of the coal-fired unit.Coal fired units can provide supplementary heat source,cooling water,demineralized water and other resources to compressed air energy storage system.The electrical conversion efficiency of the supplementary heating system is slightly higher than that of the non-supplementary heating system.
