Transient study of DC Zonal Electrical Distribution System in Next Generation Shipboard Integrated Power Systems using PSCAD™

摘要

Developing power management schemes for the Next Generation Integrated Power System (NGIPS) for ships requires an adequate model of the power system. NGIPS is the subject of ongoing research in different fields and a design handbook of this system is not available yet. This paper presents a design, modeling and simulation procedure for a DC Zonal Electrical Distribution System (ZEDS) in a notional NGIPS model. PSCAD™ software is used as the EMTP simulation tool to study the system. The DC ZEDS is developed based on data available in the literature. The models of the components are designed as multi-terminal blocks including the power converter modules and required enclosures. The modeling procedure for each component includes topology selection, analytical formulation, design, and implementation in PSCAD™ software. Case studies are performed to verify the performance of developed models and study of fundamental concepts about the DC ZEDS which is subject of interest in areas such as power management and protection of NGIPS.
