摘要： A digital computer system provides automatic control for a steam turbine and two gas turbines in a combined cycle electric power plant during startup and load modes of operation. The gas turbine automatic control system provides speed, load and blade path temperature control functions in developing an output fuel control signal for application to each gas turbine fuel valve control. An analog control for each gas turbine selectively provides startup and temperature and load control functions as a backup for the automatic gas turbine control, and further provides gas turbine overspeed, surge and other limit controls continuously. An operator panel functions with the analog and digital controls to provide an operator interface with the plant, and an interface circuit ties the digital and analog controls together for bumpless transfer between manual and automatic modes of operation. A sequencer is provided for each gas turbine and it provides gas turbine startup sequence control, gas turbine trip protection and other functions in both the automatic and the backup modes of operation. A gas turbine monitor develops temperature and vibration signals for the sequencer and the fuel controls.

摘要： A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. In the automatic and manual modes of operation, the control system develops a fuel reference signal for the throttle valve position control by means of a speed/load control which functions on a feedforward speed control basis without speed feedback correction. An electrical overspeed protection control is directly coupled to the throttle valve position control to limit turbine speed to a first reference value when the breaker is closed and to limit turbine speed to a lower reference value when the breaker is open. Electrical and mechanical overspeed protection systems directly trip the turbine at higher speed references.

摘要： A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. The control system includes an automatic control and a backup control which are interfaced to operate the gas turbine throttle valve for speed and load control purposes and to provide for manual/auto transfers. The backup control includes a startup control which functions on the basis of a feedforward fuel schedule ramp function. Between ignition speed and 78% synchronous speed, the ramp function is a linear function of fuel demand versus speed with a predetermined slope. From 78% of synchronous speed to idle speed, the ramp function is a linear function with a lesser slope.

摘要： A combined cycle power plant has a number of gas turbines each feeding exhaust gas to an associated heat recovery steam generator to generate steam which is supplied to a common header. Provision can also be made for supplementary firing of the heat recovery steam generator to produce additional steam flow. The combined cycle plant also has a steam turbine with a special control system to control steam pressure in the header and to supply the balance of the plant load. An overall combined plant control system assigns load to the individual gas turbine control systems, while the steam turbine control system controls steam pressure in the common header. The steam pressure level setpoint is ramped between selected operating pressure levels when adding or removing load, in accordance with the steam turbine valve positions, in order to achieve optimum operation of the steam turbine. A steam bypass valve control system is used to control pressure in the header during startup, and a supplementary firing control for the heat recovery steam generators may be included to achieve peak loads.

摘要： A method for operating a turbine unit having at least two partial turbines, wherein a steam volumetric flow is conducted by a steam transfer device from the partial turbine arranged upstream to a partial turbine arranged downstream, which is connected after the partial turbine arranged upstream, wherein a pressure level within the steam transfer device is manipulated in accordance with a load range in which the turbine unit is operated, in such a way that the exhaust steam of the partial turbine arranged upstream remains superheated in the event of operation of the turbine unit in a partial-load range below the IGV point and/or in the event of a quick increase in the partial load.

摘要： A system and method for increasing the responsiveness of a duct fired, combined cycle power generation plant (12) via operating one or more gas turbine engines (14) at a part load condition less than 100 percent load, one or more steam turbine engines (16), and one or more supplemental burners (18) providing additional heat to a heat recovery steam generator (20) upstream from the steam turbine engine (16) is disclosed. The combination of the steam turbine engines (16) and supplemental burners (18) operating together with gas turbine engines (14) at a part load condition enables the system to quickly change output to accommodate changes in output demand of the duct fired, combined cycle power generation plant (12). By operating the one or more gas turbine engines (14) at a part load condition, the gas turbine engines (14) are able to be used to increase net output of the combined cycle power generation plant (12) faster than relying on increasing output via duct firing.

摘要： A power generation system may include a gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied. The combustor is arranged to supply hot combustion gases to the turbine component, and the integral compressor has a flow capacity greater than an intake capacity of the combustor and/or the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to an exhaust of the turbine component. An eductor positioned in the excess air flow path uses the excess air flow as a motive force to augment the excess air flow with additional gas, creating an augmented excess gas flow.
