摘要:

压缩空气储能被认为是最具发展前景的大规模物理储能技术之一,压缩机作为其关键部件对系统整体性能具有重要影响。离心式压缩机具备大流量、高压比、宽工况的运行特性,在压缩空气储能领域相对其他类型压缩机更具优势。受固定容积储气装置充气特性影响,压缩机常运行于非设计工况,对压缩机性能进行准确预测可提高系统效率,减少研发投入。20世纪50年代起,国内外学者对离心式压缩机性能预测开展了大量研究,建立了多种性能预测方法。本文将性能预测方法分为机理建模类、相似换算类与数据驱动类,在总结各方法基本原理及研究进展的基础上,定性分析了各方法在建模周期、预测精度、可移植性及适用场景等方面的差异,并对性能预测未来发展趋势进行了展望,旨在为离心式压缩机性能预测方法的研究与应用提供指导。

Abstract:

Compressed-air energy storage is considered the most promising large-scale physical energy-storage technology; in addition, the compressor, as a key component, has an important impact on the overall performance of the system. In this field, centrifugal compressors have advantages over other types of compressors with characteristics of large flow, high pressure ratio, and wide operating conditions. Owing to the influence of the charging characteristics of the fixed-volume gas-storage device, the compressor often functions in the off-design condition. The accurate prediction of the compressor's performance can improve system efficiency and reduce R&D investment. Since the 1950s, considerable amount of research has been conducted on the performance prediction of centrifugal compressors and various performance prediction methods have been established. In this paper, performance prediction methods are categorized into mechanism modeling, similarity conversion, and data-driven models. According to the summarization of the basic principles and research progress of each method, the differences of each method in terms of the modeling cycle, prediction accuracy, portability, and application scenarios are qualitatively analyzed, and the future development trend of performance prediction is prospected. The findings of this study could guide in the research and application of the performance prediction method to centrifugal compressors.

Key words: centrifugal compressors, performance prediction, compressed air energy storage
