Dynamic Simulation-Based Analysis of a New Load Shedding Scheme for a Notional Destroyer-Class Shipboard Power System

摘要

In this paper, an expert-system-based load shedding scheme (LSS) for ship power systems is revisited. In this LSS, a popular decision-making tool termed the analytical hierarchy process (AHP) is utilized for prioritizing the loads to be shed onboard a notional all-electric ship power system. The AHP-based LSS is proposed as an alternative to possibly overcome some of the major drawbacks of traditional LSSs implemented on ship power systems by minimizing the number of loads disconnected, differentiating the priority of loads based on system conditions, and considering a wider ranger of factors that may potentially influence the shedding of electrical loads. An implementation of the developed LSS to a destroyer-class shipboard power system simulated on a real-time digital simulator is presented.
