Simulation and Design of a Protection System for SMES

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 43)


The protection system of a superconducting magnetic energy storage (SMES) prototype consists of a quench detection system, bypass switches, quench heaters and a discharge circuit. The bypass switches are semiconductors that are placed within the cryogenic area. They serve for bridging the coils in the case of a quench in order to obtain a faster discharge.

A complex numerical simulation system was developed to investigate the behaviour of this protection system because both the superconductor and the semiconductor are highly non-linear. Based on the results of the simulation, the components of the protection system can be rated and the process-oriented sequential control can be optimized.
