Functional Description
IS200TRPAH2AGD is a Turbine Primary Trip Terminal Board developed by GE. It is a part of Mark VIe control system. The terminal board integrates with the PTUR turbine I/O packs or the TTUR terminal board. This compatibility ensures smooth communication and coordination within the turbine control architecture. The board includes a Fail-Safe ESTOP input designed to ensure the safe operation of the system. This input, powered by 24 V dc to 125 V dc, facilitates the removal of power from trip relays in emergency situations, minimizing potential hazards and preventing catastrophic failures.
Features
- Inputs for Turbine Speed Measurement: The board accommodates inputs for turbine speed measurement, offering flexibility in sensor types: 12 passive pulse rate devices: Distributed across the R/S/T sections, these devices utilize toothed wheels to measure turbine speed accurately. Alternatively, six active pulse rate inputs: These inputs, organized into two per TMR (Triple Modular Redundant) section, provide an alternative method for turbine speed sensing.
- Output Contacts for Main Breaker Trip Coil: The terminal board features two output contacts (24 V dc or 125 V dc) designated for the main breaker trip coil. These contacts, utilizing TMR voting, ensure reliable and synchronized operation for activating the main breaker in critical situations.
- Voltage Detection Circuits for Trip String Monitoring: Four voltage detection circuits are integrated into the board, capable of monitoring voltage levels ranging from 24 V dc to 125 V dc. These circuits serve the crucial function of monitoring the trip string, enhancing system safety and reliability by detecting abnormalities or faults.
- Fail-Safe ESTOP Input:
Installation
- Wiring Connections: Terminal Blocks TB1 and TB2- TTL pulse rate pickups, voltage detection circuits, E-STOP input, and the breaker relay connections are wired to the I/O terminal blocks TB1. Passive pulse rate pickups are specifically wired to TB2. Each terminal block is securely held down with two screws to ensure stability during operation.
Terminal blocks feature 24 terminals, capable of accommodating wires up to 12 AWG in size, providing ample connectivity options.
- Shield Termination Strip: Adjacent to each terminal block, a shield termination strip is positioned, facilitating proper grounding by connecting to the chassis ground. This helps mitigate electromagnetic interference and ensures signal integrity.
- Configuration Process: The board must be configured appropriately to establish the desired speed input connections. This configuration is achieved using jumpers JP1 and JP2, which facilitate the fanning of pulse rate pickups from the R section to the S and T PTURs.
- Jumper Configuration: Refer to manual to select the appropriate settings for JP1 and JP2 jumpers based on the desired speed input connections. Ensure that the jumpers are correctly positioned to achieve the desired configuration.
- Double-Check Connections: Before finalizing the installation, double-check all wiring connections to ensure they are properly secured and correctly routed to their respective terminal blocks. Verify that shield connections are adequately grounded for optimal performance.
- Power-Up and Testing: Once the installation is complete, power up the turbine control system and conduct thorough testing to verify the functionality of the TRPAH1A board. Test all inputs and outputs to ensure they are responding correctly and in accordance with system specifications.
System Design
- Functional Outputs: The board furnishes two contact voted trip relay outputs, pivotal for system control and safety. These outputs enable the implementation of protective measures and prompt responses based on system conditions.
- ESTOP Integration: Additionally, the board integrates an ESTOP (Emergency Stop) feature, facilitating swift system shutdown during emergencies. This functionality ensures rapid and effective response to critical events, safeguarding personnel and equipment.
- Voltage Sensing: Four voltage sensors embedded within the board enable precise monitoring of voltage levels within the system. These sensors contribute to system reliability by detecting anomalies and facilitating proactive maintenance and troubleshooting.
- TTUR Features: The TTUR terminal board supplements the functionalities provided by the board with its standard features. This combination ensures comprehensive system capabilities and compatibility with diverse operational requirements.
- Speed Inputs: It's imperative to note that the speed inputs on the TRPA board remain inactive and should not be connected when employing this board arrangement. This precaution ensures proper system operation and mitigates potential issues arising from unintended connections.
