Functional Description

DS200TCDAF1BCI is an EPROM Set developed by GE. It is a part of Mark V control system. This Erasable Programmable Read-Only Memory (EPROM) set is responsible for storing and retaining crucial firmware, control parameters, and system logic, ensuring the stable and efficient operation of turbines in power plants, industrial facilities, and energy production units.

System Redundancy in Control and Protection Mechanisms

To maximize system reliability and operational safety, the Mark V system employs multiple levels of redundancy:

• Triple-Redundant Control and Protection Sensors: The system utilizes three independent sets of sensors to monitor critical parameters such as turbine speed, temperature, pressure, and vibration. Each of the three microprocessors independently processes the sensor data, and the final control action is determined through a majority voting system, ensuring fault tolerance and preventing erroneous readings from affecting the turbine's operation.
• Voted System Output Signals: To enhance signal accuracy and reliability, the system applies redundancy even at the output level.
  
  • Critical solenoids: Signals are voted at the contact level, ensuring that safety-critical commands, such as turbine trip signals, are executed correctly.
  • Logic-level voting for contact outputs: Ensures consistency in non-critical control functions.
  • Triple-coil servo valves for analog control signals: This configuration enhances precision in fuel flow, valve positioning, and other analog-driven turbine functions, preventing errors from affecting turbine performance.

Mark V Microprocessor Technology

• At the core of the Mark V system are triple-redundant 16-bit microprocessor controllers, which ensure continuous, error-free operation of the gas turbine. These controllers are responsible for executing complex real-time computations, handling sensor data, processing control algorithms, and managing protective functions.
• The use of triple redundancy means that the system operates with three independent microprocessor controllers. If one processor fails or provides conflicting data, the system uses a two-out-of-three voting mechanism to determine the correct control action, thus preventing single-point failures from disrupting turbine operations.
