Patent Images
1. A hybrid power plant comprising:
- a gas turbine engine with a first compressor, a first combustor and a turbine to produce a first hot gas flow;
a second compressor driven by an electric motor to produce a compressed air and a second combustor to receive the compressed air to burn with a fuel and produce a second hot gas flow;
a manifold to receive the first and second hot gas flows;
a power turbine to receive the hot gas flow from the manifold and drive an output shaft;
a battery connected to the electric motor to supply electrical energy and drive the electric motor; and
,an electric generator driven by the power turbine and connected to the battery to charge the battery.

Abstract
A hybrid power plant with a gas turbine engine that produces a hot gas flow that is passed through a power turbine to drive an output shaft. A second compressor and second combustor is driven by an electric motor to produce a second hot gas flow that is passed through the power turbine to drive the output shaft. at a cruise speed, only the gas turbine engine is operated to supply hot gas to the power turbine. At low speed or idle, only the second compressor and second combustor is used to produce a hot gas flow for the power turbine. At maximum power, both the gas turbine engine and the second compressor and combustor produces hot gas for the power turbine.
