Surge protection via the installation of an anti-surge control valve is indispensable in centrifugal compression systems, and the designs of such valves are often specified in the early design phase of centrifugal compression systems. However, additional recycle valve piping, such as hot or cold gas bypass valves, could be required in the case of emergency shutdowns. Furthermore, design verification via dynamic simulations is crucial in the engineering workflow. Because of the unavailability of design guidelines in the early design phase, only late verification is possible, necessitating system redesign when dynamic simulation results evidence the need for additional protection. This study presents a compressor surge distribution map by analyzing sensitivity parameters and establishing a new dimensionless number called the “surge number” $(Ns)$. The surge distribution map is used to classify the safe and unsafe areas for surge protection using numerical threshold values. The map is to be used as a preliminary guideline for surge protection for engineers to quickly review the system and take additional protection measures in the early phase of design.

在离心式压缩系统中，通过安装防喘振控制阀来进行喘振保护是必不可少的，而此类阀的设计通常是在离心式压缩系统的早期设计阶段进行规定的。但是，在紧急停机的情况下，可能需要其他循环阀管道，例如热或冷气体旁通阀。此外，通过动态仿真进行的设计验证对于工程流程至关重要。由于早期设计阶段无法使用设计指南，因此只能进行后期验证，当动态仿真结果证明需要额外的保护时，必须重新设计系统。本研究通过分析灵敏度参数并建立一个新的无量纲数（称为“喘振数”）来显示压缩机喘振分布图。$（ñs）$。电涌分布图用于使用数字阈值对电涌保护的安全区域和不安全区域进行分类。该地图将用作电涌保护的初步指南，以便工程师在设计的早期阶段快速查看系统并采取其他保护措施。
