1. A valve system, comprising:
a valve, comprising:
a valve disk configured to restrict airflow when in a closed position and allow airflow when in an open position; andan actuator configured to move the valve disk based upon one or more commands; and a controller configured to provide the one or more commands to the actuator, wherein the controller is configured to:
obtain a turbine system data measurement;determine which range of a first range, a second range, or a third range the turbine system data measurement falls within;provide the one or more commands to the actuator according to a full-freeze mode when the data measurement falls within the first range;provide the one or more commands to the actuator according to a semi-freeze mode when the data measurement falls within the second range; andprovide the one or more commands to the actuator according to a full-operation mode when the data measurement falls within the third range; wherein the full-operation mode:
enables provision of the one or more commands to the actuator at a rapid rate;enables actuation of the valve disk to a full open position, a full closed position, or both;or both; wherein the full-freeze mode:
suspends provision of the one or more commands to the actuator for a pre-determined interval, such that no actuation of the valve disk occurs during the full-freeze mode; and wherein the semi-freeze mode:
enables provision of the one or more commands to the actuator at a rate less than the rapid rate;enables actuation of the valve disk to less than the full open position, less than the full closed position, or both;or both. |
