TURBINE ENGINE HYBRID POWER SUPPLY
First Claim
1. A hybrid power supply, comprising:
- a turbine engine, the turbine engine including one or more rotating components;
a drive shaft;
a generator connected in series through the drive shaft with the turbine engine, the generator including one or more rotating components;
an electrical energy storage device connected to receive electrical energy produced by the generator;
a controller connected to the turbine engine, the generator, and the electrical energy storage device, the controller configured to;
receive a power demand signal;
determine a power level in the electrical energy storage device;
determine available inertial energy stored at least in the rotating components of the turbine engine and the generator; and
provide one or more control signals based on one or more of the power demand signal, the power level in the electrical energy storage device, and the available inertial energy, to selectively control the performance of one or more of the functions of;
selectively powering the turbine engine to full power;
selectively turning off all fuel to the turbine engine;
selectively directing excess electrical energy from the generator to the electrical energy storage device; and
selectively storing excess energy as inertial energy.

Abstract
A method for controlling a hybrid machine is disclosed. The hybrid machine may be equipped with a turbine engine, a generator connected in series with the turbine engine, an electrical energy storage device, and a motor drivingly connected to a power output component for the hybrid machine. A controller may receive a power demand signal, determine a power level in the electrical energy storage device, determine available inertial energy stored at least in rotating components of the turbine engine and the generator, and provide one or more control signals to selectively control powering the turbine engine to full power, selectively turn off all fuel to the turbine engine, selectively store excess energy as electrical energy by directing excess electrical energy from the generator to the electrical energy storage device, and selectively store excess energy as inertial energy.
