Abstract: Methods and systems for detecting an oscillation error are provided. According to one embodiment, a system may include a controller, and a processor communicatively coupled to the controller. The processor may be configured to detect an oscillatory event and increment a delay timer based on a duration of the oscillatory event. The delay timer may be set to a predetermined delay value. Additionally, the processor may be configured to determine that the delay timer exceeds the predetermined delay value and, based on the determination, declare the oscillation error.

Abstract: Embodiments of the disclosure provide a method for controlling a power generation system during on-line maintenance. The method includes operating the power generation system in a first maintenance mode, which causes a controller of the power generation system to disable an automated response to at least one operational fault of the power generation system; monitoring a risk parameter of the power generation system or at least one sensor within the power generation system while operating the power generation system in the first maintenance mode; and operating the power generation system in a second maintenance mode in response to detecting an override command, an elapsed time exceeding a time limit, or the monitored risk parameter exceeding a safety threshold. The second maintenance mode causes the controller of the power generation system to enable the automated response to the at least one operational fault of the power generation system.

Abstract: A method, including receiving a turbine system operating parameter. The turbine system operating parameter includes an indication of a frequency variation of an electric power system associated with the turbine system. The method includes determining a correction factor to vary the output of the turbine system according to the frequency variation, wherein the correction factor is based on a droop power response and a nominal droop power ratio. The droop power response is calculated based on a gas turbine power output and a speed-load error. The method further includes varying the output of the turbine system based at least in part on the correction factor.
