摘要
压缩空气储能系统的空气透平入口压力变化较大,为了掌握该条件下透平的特性及规律,使用多学科仿真平台MSP和模块化建模工具PowerBuilder搭建了全工艺流程的300MW级压缩空气储能系统,分析空气透平在入口压力大幅变化情况下的运行特性和调节过程,揭示储气室压力大幅变化下透平膨胀比、出口温度和效率等关键参数的变化规律,确定了透平的功率调节过程及响应特性,并分析了透平入口温度对机组功率的影响和限制,为大容量压缩空气储能系统空气透平的运行和调节提供了数据支撑和科学依据。
This paper focuses on understanding the behavior of the air turbine train in a compressed air energy storage system when the inlet pressure changes.To achieve this,the study used the Multi-Subject Simulation Platform(MSP)and Modularity Power Builder(PowerBuilder)to create a mathematical model of a 300MW compressed air energy storage system.The research analyzed the dynamic characteristics of the air turbine train and its ability to regulate power output in response to changes in the reservoir's pressure.The study also examined the impact of inlet air temperature on unit output power.Results showed variations in key parameters such as expansion ratio,outlet air temperature,and efficiency,among others.This research provides valuable data and a scientific basis for developing large-capacity compressed air energy storage engineering applications.
