Abstract: A fluid monitoring system includes a controller configured to determine that a value of at least one fluid property of a fluid is greater than a threshold value, and to control actuators to identify which fluid source has the fluid with the value of the at least one fluid property greater than the threshold value. Each actuator is configured to drive a respective crossover valve between a first position and a second position to direct the fluid from a respective first fluid source to a first manifold or a second manifold and to direct the fluid from a respective second fluid source to the first manifold or the second manifold. In addition, the first manifold is configured to direct the fluid to a first sensor assembly, and the second manifold is configured to direct the fluid to a second sensor assembly.

Abstract: A system includes a control system configured to control one or more parameters of an exhaust gas recirculation (EGR) gas turbine system to control a portion of electrical power for export from a generator driven by the turbine to an electrical grid. The control system includes a closed-loop controller configured to control parameters of the EGR gas turbine system and an open-loop controller configured to temporarily control the parameters of the EGR gas turbine system to increase the portion of the electrical power exported to the electrical grid to provide a Primary Frequency Response (PFR) in response to a transient event associated with the electrical power. The open-loop controller is configured to provide control signals to increase a concentration of an oxidant in a combustor to provide the PFR in response to the transient event when the EGR gas turbine system is operating in an emissions compliant mode.

Abstract: A dynamic alarm system for operating a power plant is disclosed. The dynamic alarm system includes a sensor configured to generate a signal related to a measurement of an operation of the power plant. An interface displays a generated alarm to an operator and receives a dynamic rating value from the operator related to the generated alarm. A processor generates the alarm using the generated signal, compiles the rating value and alters an operation of the power plant from the compiled rating value.

Abstract: A method of controlling an operating temperature of a first combustion zone of a combustor of a rotary machine includes determining a current operating temperature and a target operating temperature of a first combustion zone using a digital simulation. The method further includes determining a derivative of the current operating temperature with respect to a current fuel split using the digital simulation. The fuel split apportions a total flow of fuel to the combustor between the first combustion zone and a second combustion zone. The method also includes calculating a calculated fuel split that results in a calculated operating temperature approaching the target operating temperature. The method further includes channeling a first flow of fuel to the first combustion zone and a second flow of fuel to the second combustion zone.

Abstract: An architecture and techniques for determining operation of energy-producing equipment that can increase profitability are presented. Such can be surfaced in easily understood financial market paradigms that reflect relatively complex physical models associated with the equipment. For example, buy data and sell data can be presented that reflect determined buy opportunities and determined sell opportunities. The buy opportunities can represent conditions in which it is advised to operate the equipment according to a cold part load protocol and the sell opportunities can represent conditions in which it is advised to operate the equipment according to a peak fire protocol.
