Functional Description

IS230TRPA1AG01 is a Turbine Primary Trip Terminal Board developed by GE. It is a part of Mark VIe control system. The Turbine Primary Trip Terminal Board is a component integrated within the Mark VIe system, specifically designed to interface with either PTUR turbine I/O packs or the terminal board. This board plays a pivotal role in overseeing and controlling essential turbine operations, focusing particularly on safety and trip functionalities.

Inputs and Outputs

  • 12 Passive Pulse Rate Devices: These devices are strategically distributed, with four dedicated to each R/S/T section of the turbine. They function by sensing a toothed wheel, providing accurate measurements of turbine speed across different sections.
  • 6 Active Pulse Rate Inputs: Alternatively, the board supports six active pulse rate inputs, allocated two per Triple Modular Redundant (TMR) section. This redundancy enhances reliability, ensuring continuous and accurate speed monitoring.
  • 2 24V DC (H1) or 125V DC (H2) Contacts: These contacts are crucial for TMR operation, directly linked to the main breaker coil for the trip coil. They facilitate robust and dependable trip mechanisms, enabling safe and effective turbine shutdown when required.
    Voltage Detection Circuits:
  • 4 24-125V DC Voltage Detection Circuits: These circuits are dedicated to monitoring the trip string, ensuring voltage levels remain within specified parameters. This feature enhances safety by continuously verifying the integrity of critical trip circuitry.
  • 1 24-125V DC Fail-Safe ESTOP Input: Designed as an emergency stop mechanism, this input allows for the immediate removal of power from trip relays. In emergency situations, it ensures swift turbine shutdown, preventing potential damage and ensuring personnel safety.

 

System Design

  • When integrated with a TTUR terminal board housing three PTUR I/O packs, the TRPA terminal board is connected using three cables equipped with DC-37 pin connectors on each end.
  • The terminal board provides two contact voted trip relay outputs essential for ensuring synchronized and reliable trip signals, crucial for operational safety and integrity. It also includes an emergency stop (ESTOP) functionality, enabling immediate turbine shutdown during critical situations to prevent potential damage and ensure personnel safety. Additionally, the board features four voltage sensors dedicated to continuously monitoring critical voltage levels within the trip string, enhancing safety protocols by promptly detecting and responding to deviations outside safe operating thresholds.
  • The terminal board complements this setup by providing its standard features, designed specifically to support the integration and operation of three PTUR I/O packs within the Mark VIe system. These features typically encompass comprehensive input and output capabilities essential for effective turbine control and monitoring.
  • In this operational configuration, it is crucial to note that the speed inputs on the TRPA terminal board remain inactive and should not be utilized. This approach ensures operational consistency and prevents potential conflicts in system functionality, maintaining reliability and adhering to stringent safety standards.
  • The terminal board’s seamless integration with the TTUR terminal board and PTUR I/O packs underscores its adaptability in diverse industrial environments. By providing essential trip relay outputs, ESTOP functionality, and voltage monitoring capabilities, it reinforces safety measures and operational control within the Mark VIe system.
