Abstract

An electrical power system for a watercraft including a first electrical power plant configured to operate in a variable frequency mode to output variable frequency power to a first electrical network and a fixed frequency mode to output fixed frequency power to a second electrical network. There is a first electrical load including a first high temperature superconductor (HTS) motor connected to the first electrical network and a second electrical load connected to a second electrical network. A controller selectively connects the first electrical power plant to the first electrical network and operates the first electrical power plant in a variable frequency mode to output variable frequency power to power the first HTS motor and selectively connects the first electrical power plant to the second electrical network and operates the first electrical power plant in a fixed frequency mode to output fixed frequency power to power the second electrical load.
