A distributed control system receives analysis data. The analysis data includes quality attributes of fluid samples and an indication of a plant location corresponding to the fluid samples. The system identifies one or more anomalies of fluid based upon the quality attributes of the plurality of fluid samples and attributes the one or more anomalies to one or more particular areas. The system triggers an alert, trigger control, or both, based at least in part upon the identified one or more anomalies and the attributed one or more particular areas.

System and method for plant control based on fluid quality

An approach for utilizing fuel gas to purge a dormant fuel gas circuit is disclosed. In one aspect, there is a fuel gas supply that supplies fuel to fuel gas circuits. Gas control valves, each coupled to one of the fuel gas circuits control the flow of fuel gas thereto from the fuel gas supply. A fuel purge system selectively purges fuel gas circuits from the fuel gas circuits that are dormant with fuel gas from the fuel gas supply.

Utilization of fuel gas for purging a dormant fuel gas circuit

A method and apparatus for control of redundant devices in a wind turbine is provided, comprising operating a first redundant device and at least one other redundant device such that the first redundant device is expected to fail before any of the at least one other redundant devices.

Embodiments of the present invention have the technical effect of automatically testing an overspeed protection system of a powerplant machine comprising at least one shaft. An embodiment of the present invention may automatically test the overspeed protection system while the powerplant machine is decelerating from full-speed-no-load (FSNL). Another embodiment of the present invention may automatically test the overspeed protection system of the powerplant machine while the powerplant machine is accelerating to FSNL.

Method and system for testing an overspeed protection system of a powerplant machine

Embodiments of the present invention have the technical effect of determining when to test an overspeed protection system of a powerplant machine. As described herein, embodiments of the present invention may be applied to a wide variety of powerplant machines, each comprising a shaft. After determining that test of the overspeed protection system should be performed, embodiments of the present invention may allow for a variety of methods to test the overspeed protection system.

Method for determining when to perform a test of an overspeed protection system of a powerplant machine

The present invention provides a method of controlling a turbomachine having at least one fuel supply system that uses an unchoked valve. Here, the method may determine the flow characteristics of a fuel in a fuel supply system without using a flow meter. The present invention also provides a fuel supply system with a configuration comprising at least one unchoked valve. The fuel system may not require the use of a flow meter.

Method for operating a turbomachine having a syngas fuel supply system and a non-syngas fuel supply system

A method for operating an energy system includes calculating an auto-ignition temperature of a fuel in use with the energy system, storing the auto-ignition temperature in a system memory, unloading a gas turbine associated with the energy system to a pre-determined range of operations, controlling a temperature of the exhaust flow discharged from the gas turbine, opening an exhaust bypass damper to a pre-determined position to enable a pre-determined volume of air to enter an exhaust flow path defined within the energy system, and releasing the energy system for normal operation after a pre-determined amount of time has elapsed.
