Functional Description

DS200TCEAF1ACK is a Software PROM Set developed by GE. It is a part of Mark V control system. It is a part of the Emergency Overspeed Board. The Emergency Overspeed Board (TCEA), located in the Protective Core P1, plays a crucial role in high-speed protection circuitry and is often referred to as the Protective Processor.

Emergency Overspeed Board Features

  • Signal Processing and Communication: Each TCEA board is responsible for scaling and conditioning the incoming signals before writing them over the IONET to the STCA board in the R1 core. The connection is made via the JX1 connector located on the board in the X position. This setup ensures that the high-speed protection signals are accurately processed and communicated for further action. The TCEA boards in the Y and Z positions (locations three and five, respectively) also play a significant role in this system. These boards transfer their information using both JX1 and JX2 connections via the X board. This hierarchical transfer of data helps consolidate the signals before they are processed further.
  • Data Utilization and Processing: The I/O Engine in the R1 core utilizes the data from all three TCEA boards. It performs a median select on the three values, ensuring that the most accurate and reliable data is used for decision-making. The results of this median selection process are then transferred across the COREBUS to the Control Engine, which uses this information to make critical control decisions for the turbine system.
  • Trip Signal Mechanism: Each TCEA board is responsible for sending emergency trip signals to the TCTG. These trip signals are sent to different relays on the board. The board employs a 2/3 voting mechanism at the relay driver level to determine whether a trip should be initiated. This voting process ensures that a single fault or erroneous signal does not lead to an unnecessary turbine trip, enhancing the reliability and safety of the system.
  • Power Supply and Diagnostics: Each TCEA board is equipped with its own power supply and power supply diagnostics. This independent power supply system ensures that the boards can operate reliably without being affected by power issues in other parts of the system.
