Functional Description

IS200TRPAH1B is an Turbine Primary trip terminal board developed by GE. It is a part of Mark VIe control system. The turbine primary trip terminal board is designed to seamlessly integrate with the PTUR turbine I/O packs or the TTUR terminal board, serving as an integral part of the advanced Mark VIe control system. This board plays a critical role in managing various inputs and outputs, ensuring the safe and reliable operation of the turbine.

Features

  • Passive Pulse Rate Devices: The terminal board accommodates 12 passive pulse rate devices, with four dedicated to each R/S/T section of the turbine. These devices work by sensing toothed wheels to measure the turbine's rotational speed accurately. By monitoring the pulse rate, the board can assess the turbine's performance and ensure its optimal operation.
  • Active Pulse Rate Inputs: Alternatively, the board also supports six active pulse rate inputs, with two inputs allocated to each TMR (Triple Modular Redundant) section. These active inputs provide an alternative method for measuring turbine speed, enhancing the redundancy and reliability of speed measurement in TMR systems.
  • TMR Voted Output Contacts: The board is equipped with two sets of output contacts, either 24 V DC (H1) or 125 V DC (H2), which are TMR voted. These contacts are connected to the main breaker coil responsible for initiating the turbine trip coil. This crucial functionality ensures swift and precise response during critical situations, such as emergency shutdowns.
  • Voltage Detection Circuits: To enhance safety and monitor the turbine trip string, the terminal board incorporates four 24-125 V DC voltage detection circuits. These circuits continuously monitor the voltage levels, providing crucial feedback on the status of the trip string.
  • For TMR systems, the signals originating from the board fan out to multiple connectors, including PR3, PS3, PT3, JR4, JS4, and JT4 connectors. This distributed arrangement allows for efficient and reliable communication with other connected components, enabling seamless coordination within the TMR system.

Installation

  • Turbine primary trip terminal board facilitates the connection of various critical components to the I/O terminal blocks TB1 and TB2. These connections play a crucial role in ensuring the safe and efficient operation of the turbine within the Mark VIe control system. Here's an expanded explanation of the connections and configurations:
  • TTL Pulse Rate Pick-ups: The TTL pulse rate pick-ups, responsible for sensing turbine speed, are wired to the I/O terminal block TB1. These high-speed digital sensors accurately measure the rotational speed of the turbine rotor and provide real-time feedback to the control system for precise monitoring and control.
  • Voltage Detection Circuits: The voltage detection circuits, which monitor the trip string voltage, are also wired to the I/O terminal block TB1. These circuits continuously monitor the voltage levels of the trip string, providing essential information for the system's safety and protection mechanisms.
  • E-STOP Connection: The E-STOP function, a critical emergency stop feature, is wired to the I/O terminal block TB1. This connection ensures that in emergency situations, the turbine can be rapidly and safely shut down to prevent any potential hazards or damages.
  • Breaker Relay: The breaker relay, a vital component for controlling the main breaker coil, is also wired to the I/O terminal block TB1. This relay ensures a reliable and rapid response during the trip coil operation, facilitating immediate turbine shutdown when needed.
  • Passive Pulse Rate Pick-ups: The passive pulse rate pick-ups, which are dedicated to measuring turbine speed in each R/S/T section, are wired to the I/O terminal block TB2. These passive devices sense toothed wheels, providing accurate turbine speed feedback for each section of the turbine.
  • Each terminal block, TB1 and TB2, is securely held in place with two screws, ensuring stable connections and preventing any accidental disconnections due to vibrations or movements.
  • The terminal blocks feature 24 terminals each, accepting wire sizes up to #12 AWG, allowing for easy and convenient wiring connections. To ensure proper grounding and minimize interference, a shield termination strip is attached to chassis ground, located immediately to the left of each terminal block.
  • To configure, users can refer to a specific table that provides guidance on the proper settings. Jumpers JP1 and JP2 on the board are used to select the fanning of the R section pulse rate pickups to the S and T PTURs. This configuration option allows for flexible customization based on the turbine's specific operational requirements and speed input preferences.
  • The turbine primary trip terminal board serves as a critical hub for connecting and managing various inputs and outputs, providing essential speed measurement, voltage monitoring, and control functions. Its robust design, convenient terminal blocks, and customizable configurations make it an indispensable component in ensuring the safe and efficient operation of gas turbines within the Mark VIe control system.
