Abstract:

The performance of turbine compressors plays a crucial role in the overall efficiency of large-scale compressed gas energy storage systems. Surge, an inherent characteristic of turbo-compressors, cannot be eliminated but can be suppressed, significantly affecting the operational efficiency, safety, and stability of compressors. Thus, anti-surge technology is essential for ensuring the safe and stable operation of turbo-compressors, particularly in compressed gas energy storage systems, where compressors frequently start and stop. This study reviews recent developments in turbo-compressor anti-surge technologies, focusing on four key areas: First, it discusses the physical characteristics of turbo-compressor surge, including the mechanism behind surge generation, identification techniques, and flow field characteristics when a surge occurs. Second, it provides an overview of the progress in three anti-surge control approaches and their respective advantages and disadvantages, including passive control to prevent surge by limiting the compressor inlet flow, active control to prevent surge by changing the compressor performance, and active/passive control that combines active control and passive control. Third, it examines compressor surge detection technologies based on signal analysis and processing. Finally, it explores future trends in turbo-compressor anti-surge technologies. A comprehensive analysis indicates that a combination of an in-depth understanding of surge characteristics, a well-designed anti-surge control strategy, and advanced surge detection technologies can effectively suppress compressor surges.
