Abstract: A method of operating a power plant includes generating, with one or more power generators, a total plant power. The method further includes providing a first portion of the total plant power to one or more auxiliary devices to meet an auxiliary demand. The method further includes providing a second portion of the total plant power to a flexible firm skid disposed within the power plant to meet a flexible firm demand. The method further includes providing a third portion of the total plant power to a power grid outside of the power plant to meet a grid demand. The method further includes receiving an increase in the grid demand that exceeds a power ramp rate of the one or more power generators. The method further includes adjusting an operation of the flexible firm skid to modify the flexible firm demand in response to the increase in the grid demand.

Abstract: Gas turbine systems and methods of operation are provided. The gas turbine system includes a combustion section having at least one combustor and an ammonia supply system. The method includes generating flash-atomizing ammonia. The flash-atomizing ammonia is generated by pressurizing ammonia from the ammonia supply system to an injection pressure that is greater than a combustion chamber pressure within the combustor. The flash-atomizing ammonia is further generated by heating the ammonia to an injection temperature greater than a boiling temperature of ammonia at the combustion chamber pressure. The method further includes providing the flash-atomizing ammonia to the combustor.

Abstract: A method of forming a component. The method includes applying a thermal barrier coating to the component to facilitate decreasing heat transfer to the component, wherein the thermal barrier coating includes at least one thermal insulating layer and a metallic bond coat layer in contact with an outer surface of the component. The method also includes forming a plurality of grooves in the at least one thermal insulating layer of the thermal barrier coating to facilitate increasing a strain tolerance of the thermal barrier coating, wherein each of the plurality of grooves extends a depth into the at least one thermal insulating layer. The method further includes depositing a material within the plurality of grooves to facilitate increasing an amount of thermal protection of the metallic bond coat layer within those areas of the thermal barrier coating in which the plurality of grooves are formed.

Abstract: A gas turbine engine combustor includes: a head end section containing a fuel nozzle assembly and defining a head end air plenum; and a liner extending downstream from the head end section toward an aft frame and defining a combustion chamber therein. First injectors are disposed at a first axial location spaced apart from the head end section to direct a first fuel/air mixture through the liner. A dynamics mitigation system includes cold-side resonators disposed wholly within the head end air plenum, each resonator of the plurality of cold-side resonators having a resonator body with a closed end and an open neck extending from the resonator body opposite the closed end. Each resonator body defines a respective volume, and the open neck is in fluid communication with the head end air plenum. In some embodiments, quarter-wave tube dampers are installed within the fuel nozzle assembly of the head end section.

Abstract: A nozzle segment includes an inner band, an outer band, and at least one nozzle vane extending between the inner and outer bands. The outer band includes a hook that extends radially outwardly from an outer surface. The hook is oriented to couple to a support within different first and second turbine engines. The hook extends circumferentially across the outer surface and includes slots defined therein. A first slot includes a first circumferential load surface, and a second slot includes a second circumferential load surface. When the nozzle segment is coupled within the first turbine engine, the first circumferential load surface engages an anti-rotation element while the second circumferential load surface does not engage an anti-rotation element. When the nozzle segment is coupled within the second turbine engine, the second circumferential load surface engages an anti-rotation element while the first circumferential load surface does not engage an anti-rotation element.

Abstract: A combined cycle power plant (CCPP) includes a heat recovery steam generator (HRSG) that includes a first economizer and a condensate supply line. The HRSG receives a flow of exhaust gas from the turbine section. The CCPP further includes a fuel heating system that has a fuel supply line and a high temperature heat exchanger. The fuel supply line is fluidly coupled to the combustion section. The high temperature heat exchanger is disposed in thermal communication on the fuel supply line. A high temperature input line fluidly couples the high temperature heat exchanger to the first economizer of the HRSG such that the high temperature heat exchanger receives water from the first economizer. A recirculation line fluidly coupling the high temperature heat exchanger to the condensate supply. A hydro turbine is disposed on the recirculation line.

Abstract: A method of controlling a power converter in a power transmission network. A first amplitude limit value for a first AC current output from an AC side of the power converter is received. A second amplitude limit value for a negative phase sequence component of the first AC current is received. The negative phase sequence component is measured to provide a measured second amplitude. The negative phase sequence component is regulated to flow with a second amplitude that is the lesser of the measured second amplitude and second amplitude limit value. A positive phase sequence component of the first AC current is regulated to flow with an amplitude not exceeding a regulated third amplitude. The third amplitude is set using a function such that the second amplitude and the third amplitude provide a first amplitude for the first AC current that is substantially equal to the first amplitude limit value.

Abstract: A damper element for a vibration dampening system may be used in a body opening in a rotating blade in a turbine. The damper element includes a base member, and a spring-suspended bearing member having a disc spring fixedly coupled to the base member at a center of the disc spring, and a bearing member coupled to a first side of the disc spring at an outer portion thereof. The bearing member extends radially distal from the first side of the disc spring. With the disc spring in an elastically extended state under influence of a centrifugal force caused by rotation of the rotating blade at higher than a predefined rotational speed, the bearing member frictionally engages a first bearing surface to dampen vibration. The friction-based vibration dampening interface experiences a reduced impact of the centrifugal forces of the rotating blade by providing a counteracting force reduction using the spring.
