Abstract
A electrical power plant with a gas turbine engine that drives two electric high speed generators connected on the two ends of the engine rotor shaft in a direct drive relation without the need for a gear box. The high speed generators can be of the same or different power rating and connected in series such that the total power output can easily be changed without the need to redesign larger high speed generators. Because the generators use permanent magnets, they can be operated as motors to drive two or more compressors. A turbine can be used to drive two or more high speed generators connected in series. Since the high speed generator/motors have thrust bearings, the thrust bearing in the turbomachine can be eliminated.
Claims6
A method for increasing the electrical power generation output of a small gas turbine engine to power electric power generating plant, the power plant including:
- a first high speed generator capable to be connected to either
- a compressor or a turbine rotor shaft;
- the method comprising the steps of:
- obtaining a second high speed generator that operates at the same rotational speed as the first high speed generator;
- connecting the second high speed generator to the compressor or the turbine rotor shaft not connected to the first high speed generator;
- and,
- operating the gas turbine engine at a power level sufficient to drive both high speed generators to produce electric power.
