Abstract
A power plant for controlling the renewable energy absorbed by a hybrid power train for driving a load, and in particular compressors for a liquefied natural gas (LNG), is disclosed. The power plant analyzes the health status of its parts, and in particular of the hybrid gas turbine system, that drives the load.
Claims5
A power plant comprising:
- a hybrid power train having:
- a through a shaft,
- a gas turbine, mechanically connected to the shaft;
- an electric motor/generator, mechanically connected to the shaft;
- a variable frequency device, connected to an electric motor/generator, and a power generation plant (PG) and to a renewable energy source (PV), wherein the variable frequency device is operable to allow the electric motor/generator transforming the energy from the power gen-eration plant (PG) and the renewable energy source (PV) to drive the load or to help the operation of the gas turbine;
- and
- a plant control unit operably connected to the gas turbine,
- the electric motor/generator, and the variable frequency device,
- wherein the plant control unit is configured to control the hybrid power train to maximize the energy used coming from the renewable energy source (PV) by maximizing the driving load of the electric motor/generator, and
- wherein the load of the gas turbine is kept above the combustor premix transfer threshold (PmxLoad);
- and
- a load mechanically connected to the shaft.
