Abstract:
An electrical system for use in isolation, the electrical system comprising a main engine, said main engine being at least one of a gas turbine or a diesel engine, a generator driven by the main engine for generating a first alternating voltage, a first rectifier unit for converting the first alternating voltage generated by the generator into a direct voltage on a DC bus, and at least one inverter unit for converting the direct voltage of the DC bus into a second alternating voltage, wherein the generator driven by the main engine for generating the first alternating voltage is an asynchronous machine coupled directly to the shaft of the main engine, and that the first rectifier unit also comprises an inverter part for converting the direct voltage of the DC bus into an alternating voltage with an adjustable frequency to said asynchronous machine so as to use the machine as a motor.
