GE IS220PPROH1A｜Backup Turbine Protection Module｜
Core Features
Independent hardware protection: The overspeed protection circuit is physically decoupled from the main control system, and can still trigger shutdown when the main control fails. Under the TMR architecture, the triple module voting significantly reduces the risk of misoperation/refusal to operate.
Multidimensional security monitoring: Integrated generator synchronization and grid connection inspection (to prevent grid impact), main control watchdog (to monitor the operation status of the main control), and quick switching to backup protection logic in case of abnormalities.
Redundant communication adaptation: Dual redundant Ethernet interfaces seamlessly connect to the Mark VIe IONET network, working in conjunction with the TREAH_S terminal board to ensure reliable output of trip commands and adapt to TMR full redundancy deployment.
Diagnosis and maintenance friendly: LED displays real-time power, communication, and protection status, infrared serial port supports local diagnosis, supports hot plugging, reduces downtime for maintenance, and improves system availability.
Industrial grade stability: multi-layer PCB and surface mount technology, anti vibration, anti electromagnetic interference, suitable for harsh industrial environments such as gas/steam turbines.
Application scenarios
Gas/Steam Turbine: Independent overspeed protection, synchronous grid connection inspection, to prevent unit runaway and grid out of step, suitable for heavy-duty/aviation modified gas turbines and industrial steam turbines.
Generator set: Ensure reliable synchronization between the generator and the power grid, trigger backup shutdown in case of main control failure, and protect the stability of the power generation equipment and the power grid.
Distributed energy system: As a backup protection node for multi unit clusters, it is adapted to TMR architecture and meets high security level requirements.
Upgrade of old units: compatible with Mark VI/VIe series, can directly replace traditional backup protection modules, and enhance system security redundancy.
