Abstract: A mathematical model was established for a 500 kW-TICC energy storage system using the lumped parameter method. An algorithm was built to solve the model  with a C-language based program. The program was integrated into the North China Electric Power University’s Star-90 simulation support system for real-time dynamic modelling of the cold start of the 500 kW-TICC system. Analyses were done on the dynamics of various components including compressor, heat exchanger, storage tank, and thermal store. The simulation results show a significant impact of the intake air flow rate on the system parameters at the storage phase, whereas the effect on the gas temperature change in the gas chamber is relatively flat. This simulation errors were found to meet the actual needs of the dynamic system characteristics.

Key words: TICC-500 system, the simulation model, the dynamic characteristics
