초록

A method includes: obtaining a measurement; determining whether the measurement is in a first range, a second range, or a third range; controlling operation of a valve in a full-freeze mode when the data measurement falls within the first range; controlling the operation of the valve of the turbine system in a semi-freeze mode when the data measurement falls within the second range; and controlling the operation of the valve of the turbine system in a full-operation mode when the data measurement falls within the third range.

청구항

1. A valve system, comprising: a valve, comprising: a valve disk configured to restrict airflow when in a closed position and avow airflow when in an open position; andan actuator configured to move the valve disk based upon one or more commands; anda controller configured to provide the one or more commands to the actuator, wherein the controller is configured to: obtain a turbine system data measurement, comprising a discharge pressure error;determine which range of a steady-state range, a diverging range, or a transient range the turbine system data m...
