Abstract
Systems and methods are disclosed for automated power plant unit trip prediction and control. Power plant controls may have limited time to manage the plant loads when one of the units trips unexpectedly. To mitigate any consequences on a power grid associated with a trip event, these systems and methods may allow for prediction of such trip events. The predictions may allow a signal to be provided to a controller in sufficient time for the controller to automatically take any necessary action to mitigate any impacts of the future trip event.
Claims20
A power plant system comprising:
- memory operable to store a set of computer-executable instructions;
- one or more processors coupled to the memory, the one or more processors operable to execute the set of computer-executable instructions to:
- receive first data at a first time prior to a first future trip event and second data at a second time prior to the first future trip event, wherein the first data and second data comprise at least one of speed data, temperature data, pressure data, optical data, resistive data, or reluctance data and are associated with operation of a first type of unit at the power plant system;
- determine that the first data satisfies a first threshold value;
- determine that a first rate of change of a first type of data corresponding to the first data satisfies a first threshold rate of change indicative of the first future trip event;
- send, based on the determination that the first rate of change satisfies the first threshold rate of change, an indication that the first future trip event is likely to occur and be associated with the first type of unit;
- and
- send a signal to perform a first action to reduce an impact of a frequency fluctuation that will result from the first future trip event.
A method comprising:
- receiving, by a controller in communication with a power plant, first data at a first time prior to a first future trip event and second data at a second time prior to the first future trip event, wherein the first data and second data comprise at least one of speed data, temperature data, pressure data, optical data, resistive data, or reluctance data and are associated with operation of a first type of unit at the power plant;
- determining, by the controller, that the first data satisfies a first threshold value;
- determining, by the controller, that a first rate of change of a first type of data corresponding to the first data satisfies a first threshold rate of change indicative of the first future trip event;
- sending, by the controller and based on the determination that the first rate of change satisfies the first threshold rate of change, an indication that the first future trip event is likely to occur and be associated with the first type of unit;
- and
- sending, by the controller, a signal to perform a first action to reduce an impact of a frequency fluctuation that will result from the first future trip event.
A non-transitory computer-readable medium storing computer-executable instructions, that when executed by one or more processors, cause the one or more processors to:
- receive first data at a first time prior to a first future trip event and second data at a second time prior to the first future trip event, wherein the first data and second data comprise at least one of speed data, temperature data, pressure data, optical data, resistive data, or reluctance data and are associated with operation of a first type of unit at a power plant;
- determine that the first data satisfies a first threshold value;
- determine that a first rate of change of a first type of data corresponding to the first data satisfies a first threshold rate of change indicative of the first future trip event;
- send, based on the determination that the first rate of change satisfies the first threshold rate of change, an indication that the first future trip event is likely to occur and be associated with the first type of unit;
- and
- send a signal to perform a first action to reduce an impact of a frequency fluctuation that will result from the first future trip event.
