A 1×1 combined cycle power plant refers to a specific configuration where one gas turbine
is coupled with one steam turbine to generate electricity.
Brief presentation of the main components:

  1. Gas Turbine (GT):
     Function: The gas turbine is the primary component that converts fuel into
    mechanical energy. It operates on the principle of burning a gaseous fuel
    (natural gas, for example) to drive a turbine.
     Components: Includes a compressor, combustion chamber, and a turbine.
    The compressor compresses incoming air, the combustion chamber ignites
    the fuel-air mixture, and the turbine extracts energy from the expanding
  2. Heat Recovery Steam Generator (HRSG):
     Function: The HRSG captures the waste heat from the gas turbine exhaust
    and uses it to produce steam. This enhances overall efficiency by utilizing
    energy that would otherwise be lost.
     Components: Typically consists of a series of heat exchangers to transfer
    heat from the gas turbine exhaust to water, producing high-pressure and
    low-pressure steam.
  3. Steam Turbine (ST):
     Function: The steam turbine converts the thermal energy in steam into
    mechanical energy. It operates by expanding high-pressure steam through
    a series of blades to drive a turbine.
     Components: Comprises a high-pressure turbine and a low-pressure
    turbine. The high-pressure steam from the HRSG is expanded in the high-
    pressure turbine, and the exhaust steam continues to the low-pressure
  4. Generator:
     Function: The generator is responsible for converting the mechanical
    energy from the turbines into electrical energy. It operates on the principle
    of electromagnetic induction.
     Components: Includes a rotor (connected to the turbine) and a stator
    (stationary part). As the rotor spins, it induces a flow of electric current in
    the stator windings, generating electricity.
  5. Cooling System:
     Function: To maintain the optimal operating temperature of various
    components, a cooling system is employed. This ensures the efficient and
    safe operation of the turbines and other critical equipment.
     Components: May include air coolers, water cooling systems, and other
    heat exchange mechanisms.
  6. Control System:
     Function: The control system monitors and regulates the operation of the
    entire power plant to optimize efficiency, respond to demand fluctuations,
    and ensure safe and stable operation.
     Components: Comprises sensors, actuators, and a central control unit that
    manages the operation of the gas and steam turbines, as well as other
    auxiliary systems.
