Abstract
Official abstract text for this publication.
A control system for at least one of steam turbines, gas turbines or power plants includes a sensor system configured to monitor predefined operating parameters, the sensor system including redundant sensors. A central processor arrangement of the control system has an input side configured to receive measurement data from the sensor system and an output side configured to communicate with operation control elements of the turbines or power plants. A sensor side processor circuit is assigned at least to the redundant sensors, the processor circuit being configured to continuously check the sensors for error-free operation, to protect or block the input side of the central processor arrangement from erroneous signals, and to only respectively forward or further process signals from a sensor that has been identified as error-free in one channel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for at least one of steam turbines, gas turbines or power plants, the control system comprising: a sensor system configured to monitor predefined operating parameters and including redundant sensors; a central processor arrangement having an input side configured to receive measurement data from the sensor system and an output side configured to communicate with operation control elements of the turbines or power plants; a sensor side processor circuit assigned at least to the redundant sensors, the processor circuit being configured to continuously check the sensors for error-free operation, to protect or block the input side of the central processor arrangement from erroneous signals, and to only respectively forward or further process signals from a sensor that has been identified as error-free in one channel; wherein the sensor-side processor circuit is configured to transform the signals from a sensor operating in an error-free manner according to a predefined requirement profile of the central processor arrangement; and wherein the sensor-side processor circuit is configured to control a display for reporting defective sensors.
