Marine Full Electric Propulsion Power System

This example shows a representative marine half-ship electrical power system with base load, hotel load, bow thrusters and electric propulsion.

System Overview

The principal components of the system are:

  • 30 MVA Gas Turbine, Round Rotor Alternator

  • 5 MVA Diesel Generator, Salient Pole Alternator

  • 11.5 MVA Base Load

  • 6 MVA Switched Hotel Load

  • 20 MVA Average-Value Propulsion Rectifier

  • 1 MVA Direct Online Start, Squirrel Cage Bow Thrusters

open_system('pe_marine_electrical_system');

Scenario Overview

The sequence of events during the simulation is:

  • 10 seconds - Hotel Load disconnected

  • 20 seconds - Propulsion begins ramping up

  • 30 seconds - Full power ahead

  • 40 seconds - Propulsion begins ramping down

  • 50 seconds - Bow Thrusters start up

  • 60 seconds - Hotel Load connected

To view results, run the simulation. Summary results are available in a Simulink® Scope.
