RAMP RATE CONTROL FOR A GAS TURBINE

摘要

A method for operating a gas turbine is disclosed. The method can include receiving a command for a new load set-point for a gas turbine. In response to the received new load set-point, a fuel valve of the gas turbine can be metered to a first position, the first position corresponding to a first gas turbine load less than the new load set-point. After a first predetermined time, the fuel valve can be metered to a second position, the second position corresponding to a second gas turbine load greater than the first gas turbine load and less than the new load set-point. The fuel valve is incrementally metered more open until the gas turbine is operating at the new load set-point.

1. A method for operating a gas turbine, comprising:
receiving, at a controller, a command for a new load set-point for a gas turbine; in response to the received new load set-point, metering a fuel valve of the gas turbine to a first position, the first position corresponding to a first gas turbine load less than the new load set-point; after a first predetermined time, metering the fuel valve to a second position, the second position corresponding to the new load set-point; and operating the gas turbine at the new load set-point.
