Abstract:
1. An electrical distribution system for use with a gas turbine engine, the system comprising: a plurality of generators including a primary generator and a secondary generator, the plurality of generators configured to be connected to a gas turbine engine and to output power, the plurality of generators driven at mechanical frequencies that differ from each other; a common bus configured to receive the power output from the generators; one or more converters disposed between each generator and the bus, the one or more converters configured to influence the frequency of the power output from the generators; and a control system configured to (i) set an AC bus frequency in accordance with the power output from the primary generator and (ii) control the converters of the secondary generator to match the primary generator so that the converters feed energy into or draw energy from the generators so that all generators supply the power output at the bus frequency.
