ABSTRACT:
For use in combination with a turbine control system, an automatic signal selector to assure selection of a valid signal representation of an operating parameter of the controlled turbine. Redundant sensors provide multiple redundant signals representing the operating parameter. Each signal is applied to a corresponding range detection circuit which generates an alarm signal whenever the sensor signal is higher or lower than preselected values. Simultaneously, each sensor signal and each alarm signal is applied to a selector network which selects one of the sensor signals as a valid signal for turbine control purposes. Thus, if any one of the alarm signals is present, indicating that at least one sensor signal is outside the preselected range, the highest valued sensor signal is automatically selected for control purposes. On the other hand, if no alarm signals are present, the control signal is automatically selected to be an intermediate valued one of the sensor signals. A protective action signal is generated in the event all sensor signals are outside the preselected range of values.
