FUNCTIONAL DESCRIPTION:

DS200LRPAG2B is a Linear Redundant Processor Board manufactured and designed by General Electric as part of the Mark V Series used in GE Linear Microprocessor Control Systems. This board features a redundant processing architecture, where two processors (primary and backup) operate in parallel, ensuring continuous control over the turbine even if one processor fails. The primary function of the board is to process control signals related to turbine performance, such as speed, temperature, pressure, and load. In the event of a failure in the primary processor, the backup processor automatically takes over, maintaining uninterrupted turbine operation. This redundancy is crucial for industries like power generation and oil and gas, where uninterrupted turbine performance is essential for safety and efficiency.

FUNCTIONS OF LINEAR REDUNDANT PROCESSOR BOARD:

• Control Processing: The LRP board processes various control signals related to the turbine’s operation. It monitors parameters such as speed, load, temperature, and pressure to ensure the turbine runs at optimal efficiency and within safe operational limits.

• Fault Tolerance: The DS200LRPAG2B ensures that the system has fault tolerance. If one processor fails or encounters an issue, the backup processor (LRP) takes over without the need for manual intervention. This failover mechanism is crucial in critical environments like power generation, where downtime or failure could lead to significant financial and safety risks.

• Real-Time Monitoring: The LRP continuously monitors the system and performs diagnostics. If a failure occurs or the system detects abnormal behavior in the primary processor, the LRP triggers an automatic switch to the redundant processor.

• Signal Communication: The LRP board handles communication between the various components of the turbine control system. It processes control signals that are sent to and received from other control boards, sensors, and actuators. For example, it may adjust turbine speed based on input from sensors or handle other system parameters such as fuel flow or exhaust pressure.

• Seamless Integration: The LRP Board is designed to integrate seamlessly with other components in the GE Mark V system. These components include input/output (I/O) modules, safety systems, and other processors. This integration ensures that all aspects of turbine operation are harmonized for reliable performance.

• Redundant Power Supply: For added reliability, the board typically operates with redundant power supplies. This ensures that even if one power supply fails, the system continues to function without any disruption.

FREQUENTLY ASKED QUESTIONS:

What is the function of the Linear Redundant Processor Board in turbine control systems?

The Linear Redundant Processor Board is integral to the turbine control system's reliability. It houses two processors that work in parallel to ensure continuous operation by providing redundancy. One processor serves as the primary, while the other functions as a backup. In case of failure in the primary processor, the backup takes over without interrupting control and data processing, ensuring zero downtime in turbine operations.

How do the processors in the Linear Redundant Processor Board communicate with each other?

The two processors in the Linear Redundant Processor Board communicate using shared memory or a dedicated interprocessor communication bus. They maintain synchronization through a continuous exchange of status updates, control data, and diagnostic information. This allows the backup processor to stay up to date with the operations of the primary processor and be ready to take control if necessary.

What is the synchronization mechanism between the two processors?

The synchronization mechanism is software-driven and involves real-time data mirroring. Both processors are programmed to handle the same tasks simultaneously, with each processor reading from and writing to the shared memory. Any changes made by the primary processor are mirrored by the backup processor, ensuring that if the primary processor fails, the backup can instantly assume control without loss of data integrity or process disruption.
