SIMULATION AND PERFORMANCE ANALYSIS OF A SHIPBOARD GAS TURBINE EMERGENCY GENERATOR SET

The objective is to model and simulate using an Analog computer the performance of a relatively complex engineering system. The results of the simulation are validated by a comparison of the simulation with the measured performance of the prototype system. The prototype system consists of a single shaft gas turbine engine driving a three-phase alternator. The alternator load is a variable speed three phase wound rotor induction motor which drives a ship bow thruster propeller. In order to provide sufficient data to validate the simulation, the alternator speed, current and terminal voltage, KW load, and induction motor speed are recorded continuously as the motor is switched through five speeds. The recorded transients in these variables are then used to validate the model and simulation. The correlation between the simulation and the prototype performance is excellent. The models used are relatively simple and yet can provide close estimates of the system performance and can demonstrate how performance varies as the system parameters are changed.
