Functional Description
DS200SLCCF1AEB is a Software EPROM Set designed and developed by GE. It is a part of the Mark V control system. The control system is equipped with triple-redundant 16-bit microprocessor controllers, leveraging the latest advancements in microprocessor technology. This redundancy enhances system reliability by providing backup processing capability in the event of a failure in one controller. Critical control and protection parameters employ a two-out-of-three voting redundancy scheme. This redundancy mechanism ensures robustness and reliability by comparing signals from multiple sources and taking action based on the majority vote.
Features
- Software-Implemented Fault Tolerance (SIFT): SIFT technology enhances system resilience by detecting and mitigating faults within the software. This proactive approach to fault tolerance minimizes the impact of potential software errors, thereby maintaining system integrity and reliability.
- Triple-Redundant Critical Sensors: Critical control and protection sensors are triple redundant, with signals voted by all three control processors. This redundancy scheme enhances sensor reliability and accuracy, ensuring precise monitoring and control of critical parameters.
- Voting of System Output Signals: System output signals undergo voting at multiple levels to maximize reliability. Critical solenoids are voted at the contact level, while remaining contact outputs are voted at the logic level. Additionally, three coil servo valves are employed for analog control signals, further enhancing reliability during operation.
- Independent Protective Module: An independent protective module provides triple redundant hardwired detection and shutdown capabilities for overspeed and flame detection. This module plays a critical role in ensuring the safety and integrity of the turbine system, with backup functions to synchronize the turbine generator to the power system.
- Synchronization Redundancy: Synchronization of the turbine generator to the power system is backed up by a check function in the three control processors. This redundancy ensures precise synchronization and alignment with the power grid, minimizing the risk of synchronization errors or discrepancies.
Software Configuration Tools
- ST2000: ST2000 is a DOS-based set of software tools specifically designed for configuring GE DIRECTO-MATIC 2000 control equipment. This comprehensive software suite provides a range of functionalities to effectively manage and customize the control system according to specific requirements.
