Abstract

The Dalian Advanced Light Source (DALS) test facility requires a 370 W cryoplant to provide cooling for four test benches. Dynamic simulations are critical for optimizing process design, refining control strategies, and enhancing operational efficiency in large-scale cryogenic systems. This study develops a comprehensive dynamic simulation model of the DALS cryogenic system using EcosimPro, encompassing both the cryoplant and distribution system. The cryoplant model integrates key components, control loops, and sequential control strategies, validated through three operational modes with results showing strong agreement with experimental data. The cooldown process of the vertical test bench is validated against experimental data, demonstrating the model’s accuracy. Furthermore, an automated cooldown method with a controlled rate is proposed and successfully implemented, providing significant operational improvements. This model serves as a valuable tool for resolving operational challenges, optimizing system performance, and training future operators of cryogenic systems.

DALS试验装置低温系统的动态仿真

大连先进光源（DALS）测试设施需要一个370瓦的低温装置来为四个试验台提供冷却。在大型低温系统中，动态模拟对于优化工艺设计、改进控制策略和提高运行效率至关重要。本研究利用EcosimPro开发了DALS低温系统的综合动态仿真模型，包括低温装置和分配系统。低温装置模型集成了关键组件、控制回路和顺序控制策略，并通过三种操作模式进行了验证，结果与实验数据非常吻合。利用实验数据对垂直试验台的冷却过程进行了验证，验证了模型的准确性。此外，提出了一种控制速率的自动冷却方法，并成功实施，显著改善了操作。该模型可作为解决操作挑战、优化系统性能和培训未来低温系统操作人员的宝贵工具。
