A Structure Preserving Power System Frequency Model for Dynamic Positioning Vessels

Abstract

This paper adapts a structure preserving model to on-board power plants. The model, originally developed for land-based power systems, is expanded for the larger frequency range allowable to on-board plants. State-space equations are developed from first principles and transformed to a form suitable for analysis and computer implementation. Recommendations for parameter selection are given. An example plant scenario is simulated both in the proposed framework and in a higher fidelity model for comparison.
