GE IS220PPROS1B｜Emergency Turbine Protection I/O Pack｜
Core Features
Strengthen safety voting: Upgrade to triple hardware overspeed protection voting logic, significantly reduce the probability of false tripping/refusal tripping, meet SIL 2 safety level requirements, and adapt to high reliability unit scenarios.
Improved anti-interference performance: The isolation level has been raised to 2500V AC, and the signal filtering algorithm has been optimized to withstand strong electromagnetic interference (such as the surrounding environment of high-voltage equipment in power plants), resulting in higher accuracy in speed signal acquisition.
Synchronization check optimization: Added real-time monitoring of voltage amplitude/frequency difference, automatic verification before grid connection, to prevent the impact of asynchronous grid connection of generators on the power grid and units.
Diagnostic function extension: Supports speed channel drift self calibration, online monitoring of relay contact status, and fault information can be uploaded to ControlST software for remote diagnosis and maintenance.
Redundancy Adaptation Enhancement: Compatible with Mark VIe TMR fully redundant architecture, supports module hot plugging, and does not require downtime for replacement, improving system availability.
Application scenarios
Heavy duty gas turbine/steam turbine: As a backup of the main protection system, it prevents overspeed accidents caused by main control failure and is suitable for combined cycle power plants.
Large generator set: with dual functions of synchronous grid connection inspection and overspeed protection, it ensures stable connection between the generator and the power grid, avoiding asynchronous grid connection faults.
Petrochemical/metallurgical self owned power plants: safety protection for rotating equipment such as compressors and pump sets, suitable for multi unit cluster control scenarios.
High safety level industrial scenario: meets SIL 2 certification requirements and is suitable for projects with strict standards for equipment safety redundancy.
