Abstract

In compressed air energy storage systems, throttle valves that are used to stabilize the air storage equipment pressure can cause significant exergy losses, which can be effectively improved by adopting inverter-driven technology. In this paper, a novel scheme for a compressed air energy storage system is proposed to realize pressure regulation by adopting an inverter-driven compressor. The system proposed and a reference system are evaluated through exergy analysis, dynamic characteristics analysis, and various other assessments. A comprehensive performance analysis is conducted based on key parameters such as thermal storage temperature, component isentropic efficiency, and designated discharge pressure. The results show that the novel system achieves a relative improvement of 3.64% in round-trip efficiency, demonstrating its capability to enhance efficiency without significantly increasing system complexity. Therefore, the system proposed offers a viable solution for optimizing compressed air energy storage systems.

基于变频器驱动压缩机压力调节的新型中温压缩空气储能系统性能分析

在压缩空气储能系统中，用于稳定储气设备压力的节流阀会造成巨大的能耗损失，而采用变频驱动技术可以有效改善这一问题。本文提出了一种压缩空气储能系统的新方案，通过采用变频器驱动压缩机来实现压力调节。通过能耗分析、动态特性分析和其他各种评估，对提出的系统和参考系统进行了评估。根据蓄热温度、组件等熵效率和指定排气压力等关键参数进行了全面的性能分析。结果表明，新型系统的往返效率相对提高了 3.64%，这表明它能够在不显著增加系统复杂性的情况下提高效率。因此，所提出的系统为优化压缩空气储能系统提供了可行的解决方案。
