Abstract: Systems and methods for health monitoring and upgrade of a distributed controller are provided. According to one embodiment of the disclosure, a method for health monitoring and upgrade of a distributed controller may commence with receiving, by a lower level controller from a high-level controller, high-level control references. The method may further include generating low-level control references for a hardware asset based at least in part on the high-level control references. The method may include monitoring the network connection and detecting an error in the network connection. In response to the detection of the error in the network connection, a control of the hardware asset may be transferred to the low-level controller. The method may further include determining that the network connection has been restored. In response to the determination that the network connection has been restored, the control of the hardware asset may be transferred to the high-level controller.

Abstract: A gas turbine system includes a combustor configured to combust an oxidant and a fuel in the presence of an exhaust gas diluent to produce combustion products, an oxidant supply path fluidly coupled to the combustor and configured to flow the oxidant to the combustor at an oxidant flow rate, and a turbine configured to extract work from the combustion products to produce an exhaust gas used to generate the exhaust gas diluent. The turbine causes a shaft of the gas turbine system to rotate when the work is extracted from the combustion products. The system also includes an electrical generator that generates electrical power in response to rotation by the shaft, and a controller that performs load control in response to a target load by adjusting the oxidant flow rate along the oxidant flow path as a primary load control parameter.

Abstract: In one embodiment, a system includes a turbine combustor having a combustor liner disposed about a combustion chamber, a head end upstream of the combustion chamber relative to a downstream direction of a flow of combustion gases through the combustion chamber, a flow sleeve disposed at an offset about the combustor liner to define a passage, and a barrier within the passage. The head end is configured to direct an oxidant flow and a first fuel flow toward the combustion chamber. The passage is configured to direct a gas flow toward the head end and to direct a portion of the oxidant flow toward a turbine end of the turbine combustor. The gas flow includes a substantially inert gas. The barrier is configured to block the portion of the oxidant flow toward the turbine end and to block the gas flow toward the head end within the passage.

Abstract: A non-transitory, computer readable medium stores instructions executable by a processor of an electronic device. The instructions include instructions to determine that a transient event is occurring in an electrical grid coupled to an EGR gas turbine system, wherein the transient event is an under-frequency or an under-voltage event. The instructions also include instructions to increase a flow rate of fuel to a combustor of the EGR gas turbine system in response to the transient event when the EGR gas turbine system is operating in a non-stoichiometric combustion mode. The instructions further include instructions to increase a flow rate of oxidant to the combustor before increasing the flow rate of fuel to the combustor, or to decrease a local consumption of the electrical power to increase a portion of the electrical power that is exported to the attached electrical grid, or both, in response to the transient event when the EGR gas turbine system is operating in a stoichiometric combustion mode.
