One of the most important issues that need to be resolved before DC power systems are feasible to be introduced as architectures for naval marine power systems (MPS) is the protection of the system against faults. Techniques are being developed to control fault current levels by fast acting control using power electronic systems. These techniques need to be supported by a system that classifies and...
A small scale laboratory demonstrator has been constructed to represent a zonal DC distribution system as proposed for future naval vessels. This paper describes how the demonstrator has been used to validate a proposed fault location strategy - Active Impedance Estimation (AIE) - under experimental conditions. The practical processing algorithms required to reduce the effect of noise and the background...
