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.
