Functional Description

DS200DMCBF1CFA is a GE Software PROM Set designed and developed by GE. It is a part of the Mark V control system.�Mark V systems incorporate redundancy features, such as multiple controllers and power supplies, to enhance system reliability and availability. The system often includes communication interfaces that allow it to connect with other control and monitoring systems. This communication capability enables data sharing and remote monitoring.

Mark V Control Configuration Features

• Mark V Control Configuration, as depicted in Figure 5, represents an advanced and highly reliable control system designed for medium- to large steam turbines. This system features a triple modular redundant (TMR) setup, ensuring that critical functions are performed with maximum redundancy and reliability, particularly in the context of industrial and power generation applications.
• At the heart of this system are three identical controllers, referred to as R, S, and T. These controllers are responsible for executing all critical control algorithms, protective functions, and sequencing required for the operation of the steam turbine. They acquire essential data from various sensors and generate outputs that directly impact the performance of the turbine. This robust configuration is integral to maintaining the safety and efficiency of the steam turbine.
• Protective functions and outputs, particularly for critical aspects such as overspeed protection, are channeled through the P module. This module comprises triple redundant processors labeled as X, Y, and Z. These processors operate independently, providing an additional layer of protection for vital functions. Their ability to detect and respond to anomalies is crucial in ensuring the overall safety of the system.
• The three control processors, R, S, and T, gather data from a set of triple-redundant sensors as well as from dual or single sensors, depending on the specific requirements of the turbine type. A diverse range of sensors, as described in Table 3, is employed to monitor various parameters. The selection and quantity of sensors are tailored to the specific turbine's needs. For critical aspects related to continuous control and protection, triple-redundant sensors are deployed to ensure high reliability. In other cases, dual or single sensors are used, with data distributed to all three control processors to maintain redundancy.
• The remarkable reliability of the TMR control system is greatly attributed to the utilization of triple sensors for all critical parameters. This approach was initially demonstrated with the triple-redundant protection system of the EHC Mark II and has been adopted as a fundamental principle in ensuring the safety and functionality of complex industrial and power generation processes.
• Mark V Control Configuration offers a highly redundant and reliable system for managing medium- to large steam turbines. Through the deployment of TMR and triple sensors, it provides a robust solution that not only enhances system safety but also ensures the uninterrupted and efficient operation of critical machinery.
