摘　　要：为了支撑能源转型、提高风光能源利用率、优化电力系统运行,建立了一种新型的压缩空气抽水蓄能系统(PHCA)整体模型,综合分析了蓄能罐子系统、水力子系统、水泵水轮机系统、机械子系统的运行特点,采用最佳效率点控制方法对水泵水轮机转速进行调节,并从压力配置和无量纲流量设置方面进行仿真计算。结果表明,所建模型能使水泵水轮机快速稳定工作在高效效率区中;在蓄能罐采用较低/较高压力比时,可获得更高的蓄能罐效率;降低水泵水轮机无量纲流量值会同时影响蓄能罐效率和水泵水轮机效率,综合来看水泵水轮机效率下降对总效率的影响更大。研究结果可为压缩空气抽水蓄能系统的设计与运行提供参考依据。In order to support the energy transformation,improve the utilization rate of wind photovoltaic power and optimize the operation of power systems,a new whole model of compressed air pumped storage system was establised to analyze the operation performance of storage tank system,hydraulic subsystem,pump turbine system,and mechanical subsystem.The best efficiency point control method was used to adjust the speed of pump turbine.The simulation was carried out in terms of pressure configuration and dimensionless flow setting.The results show that the proposed model can make the pump turbine work quickly and stably in the high efficiency zone.When the storage tank adopts the lower/higher pressure ratio,there will be higher storage tank efficiency.Reducing the dimensionless flow rate of pump turbine will affect the efficiency of storage tank and pump turbine simultaneously,and the decrease of pump turbine efficiency will have a greater impact on the overall efficiency.The research results can provide reference for the design and operation of compressed air pumped storage system.
