Documentation for a Notional Two Zone Medium Voltage DC Shipboard Power System Model implemented on the RTDS

The MVDC architecture with 12 kV DC distribution represents a shift from traditional 60 Hz AC shipboard power distribution system and has the potential to provide superior power density, power quality while being affordable. The report here in provides information on ‘the two zone MVDC shipboard power system model’.
The main contribution of this report is the development of shipboard power system model in digital real-time simulator (DRTS), RTDSTM. The model is based on the zonal integrated power distribution system architecture proposed by N. Doerry in [1]. The purpose of the model described in this report is to aid the investigation of fault management (fault identification, localization and recovery) in MVDC shipboard power systems.
The individual modules implemented for model will allow the user to comprehensively test different methods of fault detection algorithms while providing useful insight into behavior of different modules. The two model versions described herein feature two distinctly different types of power generation modules (PGMs): a modular multi-level converter (MMC) based PGM and a thyristor controlled rectifier based PGM. Technical data for various modules modeled in the report have been provided along with simulation results depicting the performance of the two versions of the models.
The shipboard power system model provided in this report acts as a first pass for simulation assisted studies involving fault management in MVDC systems. The outcomes from the simulation could be useful in understanding and paving a path for controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) testing.
