Functional Description

IS210TREGH3B is a GE Turbine Emergency Trip Terminal Board developed by GE. It is a part of Mark VI series. The module supplies power to up to three emergency trip solenoids and is controlled by the I/O controller. It provides the positive DC power to the solenoids, while the TRPG terminal board supplies the negative side. The I/O controller manages emergency overspeed protection, emergency stop functions, and controls 12 relays on the TREG.

Features

  • The board powers up to three emergency trip solenoids, crucial components for initiating turbine trips during emergency scenarios. It is controlled by the system's I/O controller, ensuring precise management of emergency operations.
  • The board provides the positive side of the DC power supply to the solenoids. The associated TRPG terminal board supplies the negative side of the DC power, completing the circuit.
  • The board uses 12 relays, organized into three groups of three. These relays employ voting logic to ensure reliable and redundant control of the trip solenoids, enhancing system safety and fault tolerance.
  • The I/O controller linked to the TREG board offers emergency overspeed protection for turbines.
  • It facilitates emergency stop functions, a critical aspect of turbine operation under hazardous conditions.
  • The H3B model is a specialized version of the H1B TREG board, tailored for systems that require redundant boards. It incorporates unique features to enhance reliability in high-demand scenarios.
  • The H3B provides feedback circuits and economizing relay power exclusively through the JX1 connector, ensuring streamlined and efficient operation in redundant configurations.

Diagnostics

  • The terminal board is equipped with comprehensive diagnostic capabilities, ensuring the reliability and safety of the system. The diagnostics are managed by the I/O controller, which continuously monitors the board and its connected devices. This proactive diagnostic approach is critical for maintaining operational efficiency and identifying potential issues before they lead to system failures.
  • The diagnostics cover a wide range of components to ensure their functionality. The trip relay driver and its contact feedbacks are monitored to confirm proper operation during emergency trips. Additionally, the solenoid voltage is checked to ensure the solenoids are receiving the appropriate power supply. The system also verifies the performance of the economizer relay driver and its contact feedback, the K25A relay driver and coil, and the servo clamp relay driver. Any inconsistencies in the performance of these components trigger fault conditions, prompting immediate attention from operators.
  • The solenoid voltage source is another critical element evaluated during diagnostics. By ensuring the voltage source meets specified requirements, the system guarantees reliable performance of the trip solenoids. Any deviation from the expected values in these components results in the generation of fault alerts, which are crucial for timely troubleshooting and maintenance.
  • In addition to component diagnostics, the board’s connectors JX1, JY1, and JZ1 are equipped with ID devices. These read-only chips store key information, including the terminal board’s serial number, board type, revision number, and plug location. The I/O controller interrogates these ID devices regularly to verify hardware compatibility. If a mismatch is detected, such as an incorrect serial number or board type, the system raises a hardware incompatibility fault, signaling a potential configuration error.
  • The diagnostic capabilities are essential for ensuring safe and efficient operation in turbine control systems. By continuously monitoring key components and verifying hardware compatibility, the system minimizes downtime and enhances the reliability of turbine emergency trip mechanisms.
