Modeling and simulation of marine On-board electrical network

This paper presents detailed models and simulators for an electrical on-board marine network. A one machine network is considered, and loads are described, initially, as equivalent RL circuits based on active and reactive powers, which results in a 5^th order dynamic system. Then a more refined model with capacitances is proposed, which results in a 9^th order dynamic system. This model represents the network in a simple and yet realistic way. The behavior of this system for different load situations leads to a load classification that is briefly discussed. To perfectly know the conditions of the load commutations that are being analyzed, electrical simulators were developed in the Matlab/Simulink environment. Both simulators, for each one of the load models are here described. The RL simulator presents a very good performance, and the RLC a very large range of adaptability.
