摘　　要：本文通过对上海光源大型科学装置冷源系统的运行及控制模式进行长时间的分析研究后,针对其负荷特性,逐步探索出一些针对末端产生突变性负荷较为有效的控制方法,能够较大改善由于负荷短时间内急剧变化导致的冷水机组频繁启停现象,同时,还能利用系统群控方式的优化来达到多个冷源系统间的负荷相互平衡,减少冷水机组开启数量,达到既增加系统可靠性,又实现系统节能的目的。Based on the long time operation and control mode analysis on original cold - source system of the Shanghai Synchrotron Radiation Facility （SSRF） , especially in view of the load characteristic, we gradually find some effective control methods to solve the discontinuous load of the system. These methods can greatly solve the problem that the chillers frequently open and stop when sudden changes of load appeared. Besides, using the optimization of the group control system, we can also achieve the load balance between two cold - source systems and reduce the number of running chillers. Through these methods we can not only improve the reliability of the cold - source system, but also realize the energy conservation goal.
