System reconfiguration on shipboard DC zonal electrical system

In this paper, an automated agent based reconfiguration scheme has been proposed for the DC zonal shipboard electrical system (SES). It is shown that the scheme can reconfigure the system following a disturbance in order to maintain the continuity of supply to loads. The paper identifies the main design issues, which include the number and location of the sectionalizers, primary and secondary DC bus configurations. The paper illustrates that with proper design, the automated reconfiguration can provide the expected performance with regards to continuity and quality of supply to loads.

I. Introduction

THE faults on the SES could be due to material casualty of individual equipment (load, cable, or generator) or widespread damage due to battle damage. For a typical zone based shipboard DC electrical distribution system, the main disturbances are the generator fault, primary DC Bus fault, rectifier fault, zone flooding, secondary DC bus fault, buck Converter fault and load damage.
