Power electronic circuits have long since permeated technology sectors that pose strict requirements on reliability and safety, calling for appropriate testing and qualification tools. In particular, high-power applications introduce possibly costly or difficult testing environments. Therefore, hardware-in-the-loop (HIL) testing is being firmly established in power electronics where the component-under-test is exposed to a simulated environment. Real-time simulation is the foundation for HIL testing as not only accurate but instantaneous quantities are needed to hide the simulation from the component-under-test. The expected future increase of the complexity of simulation models for large-scale power electronic systems render any single processing node underpowered in the long run. This thesis develops a scalable real-time simulation platform designed for the simulation of large-scale power electronic systems to study switching effects and their interactions in the compound system. It explains the fundamentals of the real-time simulation of power electronic circuits and the principles of distributing a simulation to multiple processing nodes. It describes the real-time simulation platform and demonstrates its functionality and performance by real-world experiments: a hardware converter is compared to a simulation running simultaneously in real-time and a simulation of a cluster of wind turbines connected by a DC grid demonstrates the distribution of a real-time simulation.
