ABSTRACT:
A steam turbine inlet valve control system includes separately tunable valve characteristics for single valve and sequential valve operation modes. The sequential valve characteristics include both normal and alternate sequences which can be selected during operation of the steam turbine. The characteristics may be displayed to an operator and modified by graphical manipulation to simplify tuning the control system's characteristics to the steam turbine's operation. The control system also performs direct tracking of flow through the valves by converting sensed position signals to individual valve flow signals using a lift-to-flow conversion characteristic. Individual valve flow signals are summed and corrected for choked flow conditions to produce a tracked flow demand signal.
