Abstract

The dynamic modelling of the 5kW SOFC system with all balance of plants components, valves, measurement devices, heat recovery and control systems are presented. The modelling is based on the actual test-rig designed and constructed recently by Wärtsilä Corporation. The main purpose of such dynamic modelling is to collect basic understanding of system behaviour during different operational points such as load changes, shut-down, start-up, air-fuel ratio, etc. Such information is essential before designing a complete system which is going to operate stand-alone. The results from dynamic modelling help to prevent some un-foreseen characteristic that may harm the system. During the transient behaviour of the SOFC system, one is also interested in controlling the system by some key parameters such as stack temperature, pre-reformer operational temperature and burner temperature. The study describes basic design criteria and properties of the test system. Characteristics of major sub-systems such as fuel and air supply, steam supply, exhaust heat recovery, back-up power, power electronics and control system are also explained.
