A Modelica library for the thermal and electrical modelling of cryogenic and superconducting systems is presented. The library design is compatible with the electrical and fluid components from the Modelica Standard library. At the same time, several typical effects of cryogenic systems are modelled that have no equivalent in the Standard library. Easy usability and extendability of the components is emphasized. In this paper, the different parts of the library are explained in more detail. To illustrate the capabilities of the library, three showcases are presented: a simple solenoid magnet system, a current lead and a current limiter. The results show that many effects occuring in cryogenic and superconducting systems can successfully be simulated using this library.
