摘　　要：本文采用动态模拟方法,对多级压缩机系统改造方案合理性及停车工况下防喘振回路响应等方面进行分析研究,结果表明,相比于稳态模拟,动态过程可以观察压缩机工作点随时间的变化情况,模拟结果可用于分析改造项目中压缩机的可利旧性、验证防喘振系统的有效性、给出设计优化建议等方面。In this paper,the dynamic simulation method is used to analyze and study the rationality of the multi-stage compressor system modification scheme and the anti-surge loop response under shutdown conditions.The results show that compared with the steady-state simulation,the dynamic process can observe the change of compressor operating point over time.The simulation results can be used to analyze the profitability of the compressor in the renovation project,verify the effectiveness of the antisurge system,and give design optimization suggestions.
