System-Level, FPGA-Based, Real-Time Simulation of Ship Power Systems

In this paper, we present a scalable approach for real-time simulation of ship power systems with high-frequency power electronics converters (100-200 kHz). The proposed approach is based on the latency-based linear multistep compound method and relies on field-programmable gate array (FPGA) execution. Several examples of increasing dimension and complexity are used to evaluate the scalability-both of in terms of computational delay and of resources usage-of the proposed approach. Real-time execution with a 50 ns time step is achieved for all the examples considered.
