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.
Claims14
A power plant, comprising:
- a load;
- a hybrid power train having:
- a through shaft mechanically connected to the load,
- a gas turbine mechanically connected to the shaft;
- and
- an electric motor/generator mechanically connected to the shaft;
- a variable frequency device connected to the electric motor/generator, a power generation plant, and a renewable energy source, wherein the variable frequency device is operable to allow the electric motor/generator transforming the energy from the power generation plant and the renewable energy source 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 in response to health indexes for each of the gas turbine, the electric motor/generator, and the variable frequency device to maximize the energy used from the renewable energy source by increasing 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).
