Product Details

overview

 

Steam turbine emergency trip system Steam turbine monitoring is an automatic control and protection device with a programmable logic controller (PLC) as the core. The system adopts redundant commercial double CPU configuration, uses microprocessor to collect shutdown signal sent by on-site protection device, and after calculation, sends out an instruction to close the steam inlet door urgently to stop the steam turbine, and provides shutdown diagnosis information for DCS and SOE systems. Practice has proved that the whole system has high reliability and is an important protection system of the power plant.
