Abstract:

Analog computer techniques were applied to the analysis of the performance of a shipboard power system such as is found on the SSN-588 class vessel. The major components of the system, such as the ships services turbine generator set, the regulators and controls on the turbine and generator, the 300 kilowatt ac-dc motor generator and its controls, and the coolant pump drive motors and a pulsing sonar load were included in the simulation. The performance of the system was investigated for the application of the load disturbances of starting the coolant pump induction motor and the application of a sonar load for various combinations of system parameters. The results of the study were obtained in the form of analog strip chart recordings of the system variables of voltage, load current, system frequency, generator torque, etc. The results of the study showed that the initial changes in system voltage are determined by the magnitude of the disturbance and the characteristics of the generating equipment. The transient recovery from the initial voltage change is a function of the magnitude of the disturbance and the adjustments of the regulator and control equipment. Author
