Function description
The IS200TPROH1BCB is a protection terminal board developed by GE. It is part of the Mark VIe control system. TPRO plays a key role in providing critical signals to the VPRO (voting processor) board, helping to enable independent emergency overspeed and synchronization protection systems. The synergies between TPRO and VPRO, as well as the integration of TREx and TREG boards, form a comprehensive and redundant emergency overspeed and synchronization protection system. This architecture ensures the reliability and safety of turbine operation in critical situations and provides independent control and backup mechanisms.

trait
Signal input from TPRO to VPRO: TPRO is the source of basic signals, including speed signals, temperature signals, generator voltage, and bus voltage. These signals are essential for monitoring the turbine’s operating parameters and ensuring system safety.
Triple redundancy VPRO board: The VPRO board is configured with triple redundancy, emphasizing system reliability. This arrangement ensures that even if one VPRO board fails, the others can seamlessly take over, thus maintaining the integrity of the emergency overspeed protection system.
Independent module of the protection system: The protection system is controlled by a VPRO board and operates independently in a module separate from the turbine control system. This isolation enhances the robustness of emergency overspeed and synchronous protection.
TREx control of the trip solenoid valve: The trip solenoid valve is a key component in the scram function and is controlled by the VPRO board through the TREx (Turbo Relay Extension) terminal board. These terminal plates, such as TREG, TREL or TRES, help connect and coordinate the trip solenoid valves.

Cabling configuration: Cabling between TPRO, VPRO and TREx terminal boards is carefully configured to ensure seamless communication. The correct transmission of the signal is essential for the effective operation of the emergency protection system.
VPRO’s emergency trip function: The VPRO board plays a central role in providing emergency trip function. During excessive speed or other critical situations, the VPRO board activates an emergency trip, ensuring a quick and decisive response to prevent potential damage to the turbine.
Trip solenoid valves connected to TRPx terminal boards: Up to three trip solenoid valves can be connected between TREx and TRPx (TRPG, TRPL, or TRPS) terminal boards. The TREx provides the positive electrode of 125 V DC to the solenoid, while the TRPx provides the negative electrode. This configuration allows either board to trip the turbine, increasing redundancy and fault tolerance.
Control of TREG relays: VPRO controls 12 relays on the TREG board. Nine of these relays are organized into three groups of three, forming a voting mechanism to determine the inputs that control the three trip solenids. This voting mechanism ensures a robust decision-making process for emergency stopping.
Auxiliary TREG board driven by VPRO: A second TREG board can be driven from VPRO to J4, further enhancing the system’s flexibility and adaptability to specific operational requirements.

Install
Generator and bus potential transformer, analog input and thermocouple: First connect the generator and bus potential transformer to the first terminal on the TPRO. Ensure secure connections and proper insulation to maintain accurate potential measurements. Connect analog inputs and thermocouples to the same module, tidy up and mark wires for easy identification during subsequent maintenance or troubleshooting.
Magnetic tachometer: For magnetic Tachometers, use the second terminal on the TPRO. Carefully connect each pickup according to manufacturer’s specifications. Verify pickup polarity and proper alignment to ensure accurate speed signal acquisition.
Jumper configuration (JP1A and JP1B) : Find jumper JP1A and JP1B on the TPRO board. These jumpers play a crucial role in configuring analog inputs. Depending on your system requirements, set up JP1A and JP1B to achieve 4-20 mA or voltage inputs on the first of the three analog inputs. Refer to the TPRO documentation for specific jumper configurations.
For 4-20 mA inputs: Connect JP1A and JP1B accordingly to enable 4-20 mA inputs. This configuration is typically used for current-loop analog signals.

For voltage input: Adjust JP1A and JP1B to allow voltage input first analog input. This setting applies to systems that use a voltage signal within a specified input range.
Double check connections: Before completing the installation, carefully check all wiring connections. Make sure that each wire is securely secured and that there are no loose connections that could cause erratic signals or inaccurate readings.
Cable Management: Implement appropriate cable management techniques to organize and fix cabling. Use a cable tie or catheter to prevent tangling and minimize the risk of damage to the wire during operation.
System testing: After the installation is complete, a thorough system test is performed to verify the functionality of TPRO. Verify that potential transformers, analog inputs, thermocouples, and governors provide accurate and reliable signals to the TPRO board.
Calibration (if applicable) : Perform calibration procedures on connected devices and sensors if required. Calibration ensures that TPRO accurately interprets input signals, thereby improving the overall accuracy of the system.

Speed control and overspeed protection
Passive magnetic governors: Six passive magnetic governors are strategically placed within the turbine system to monitor speed. These pickups generate electrical signals based on the magnetic fields of the rotating parts, providing a valuable input for speed control and overspeed protection.
Controller monitoring: The first three speed pickups are dedicated to controller monitoring. The controller evaluates the signal from these pickups and uses the median signal for speed control. This method helps to ensure a stable and accurate representation of the turbine’s rotational speed.
Primary overspeed protection: In addition to speed control, the controller also uses primary overspeed protection. This is a key safety measure to prevent turbines from exceeding safe operating speeds. The controller continuously monitors the speed signal and takes corrective action when overspeed is detected.
Connect to VPRO: The second set of three speed pickups are connected to each of the three VPRO in the protection module. These VPRO or voting processors play a key role in independently overseeing overspeed protection features. Distributing monitoring tasks among multiple processors enhances system redundancy and fault tolerance.

Additional speed pickers available: The TPRO terminal board is designed to accommodate a total of nine passive magnetic pickups or active pulse rate sensors of the TTL type. This flexibility allows for future extension or customization to specific operational requirements.
Distribution among VPRO: Of the nine possible speed pickers, three are designated to be monitored by each of the three VPRO. This distribution ensures that each processor has a dedicated set of inputs, contributing to a distributed and efficient overspeed protection system.
Active pulse rate sensor: The terminal board supports TTL type passive magnetic pickup and active pulse rate sensor. This versatility enables the system to adapt to different sensor technologies, thus providing flexibility for sensor selection.
disposition
With the strategic use of jumpers, the terminal board can be configured for optimal performance and compatibility within the system. These jumpers are strategically placed on the board, giving users the flexibility to customize Settings according to specific requirements and operational needs. The available jumper options and their functions are outlined below:

Jumper JPA1: Select the input type
Jumper JPA1 plays a key role in determining the type of input accepted by the terminal board.
The user can choose between a current input or a voltage input configuration, depending on the nature of the signal being processed. The jumper effectively ensures compatibility with a variety of input sources and enhances the versatility of the terminal board in a variety of applications.
Jumper JPB1: Return to configuration
The configuration of the return connection is controlled by jumper JPB1. Users can choose to connect backflow to a public terminal or leave it open, depending on the specific requirements of the system. The jumper can be flexibly looped to suit different circuit configurations and operation scenarios.
By strategically positioning these jumpers, users can customize the configuration of the terminal board to effectively meet their unique needs and preferences. This configurable approach ensures compatibility, flexibility and optimal performance, enhancing the overall functionality and availability of the end boards in the system architecture.
