Combined system simulation with optimal control, selected a typical water cooled primary/secondary chilled water system, used the research achievements of Annex 30 in IEA for the reference, this work firstly presents both the basic component models and the control system component models. Secondly gives the main models for parameter identification and experiment validation. Finally a dynamic digital simulator is set up using TRNSYS as the platform to substitute a real system to test and evaluate some kinds of online optimal supervisory control strategies after giving some essential data file input and finishing all the PID controllers'tuning.
