Integrated Emergency Trip System (ETS-K)
About ETS-K
ETS-K adopts HollySys HOLLiAS ® MACS-K system as the platform, and redundant fast main controllers to form the ETS system, which continuously receives alarms and shutdown signals from the TSI system, DEH system and other equipment of the turbine generator set online, and performs comprehensive logic judgment. The system is suitable for medium and large turbine units. When the normal operation of the unit is affected, various protection signals such as shutdown, alarm and interruption of the unit are sent in time to make the turbine shut down safely, and provide shutdown diagnosis information for DCS and SOE systems.
