PROTECTIVE SYSTEM FOR AN INSTALLATION AND A METHOD FOR CHECKING A PROTECTIVE SYSTEM
Application 1619/KOL/2007 published 2008-07-11, filed 2007-11-29
The invention relates to a protective system (10) for an installation, in particular for a gas-turbine installation, in which all the fail-safe protective circuits with reaction time requirements of greater than 50 milliseconds are routed via a more fail-safe programmable logic automation system (12). For all the other protective circuits with reaction time requirements of less than 50 milliseconds, fail-safe control relays (36) are connected in a configuration which is tolerant to single faults, in which the automation system (12) can check the operation of the control relay circuit (34) cyclically during operation of the installation.
