Abstract

The conventional protection scheme, including sequential components and wide differential area protection, may not be suitable for the FREEDM system mostly because of the unique characteristics of this new system. In this paper, the characteristics of FREEDM system are analyzed and a novel protection strategy, which makes full use of the system characteristics, is presented. This protection scheme makes use not only of the system configuration but mostly of the solid state transformer capability and design, to minimize the protection configuration and communication that are needed for a successful protection strategy. A Real Time Digital Simulator (RTDS) is used to model a sample FREEDM system in order to verify the proposed protection scheme. Simulation results are presented to support the proposed idea.
