Description
IS200VTURH1BAA IS200VTURH1B is a turbine specific primary trip board developed by GE. It is a part of Mark VI control system. The turbine control board VTUR plays a pivotal role in overseeing various critical functions within the turbine system, each aimed at ensuring safe and efficient operation. Its multifaceted functions encompass a range of monitoring, controlling, and safeguarding measures that contribute to the overall integrity and functionality of the turbine system. VTUR serves as a pivotal control hub within the turbine system, orchestrating various safety, monitoring, and control functions to maintain operational integrity, safety, and efficiency. Its comprehensive functionality underscores its critical role in safeguarding turbine operations while ensuring seamless functionality across various subsystems.
Applications
Gas turbine power plants: Core control board for GE Frame 6, 7, and 9 series units (e.g., 9FA).
Steam turbine power plants: Used for speed control and synchronous operation of large steam turbines.
Combined cycle power plants (CCGT): Coordinates the complex power distribution between gas turbines and steam turbines.
Oil and gas compression stations: Monitors industrial turbines driving large centrifugal compressors.
Nuclear power plant conventional island: Serves as a key input layer for the turbine control system (TCS).
Features
1 Turbine Speed & Overspeed Protection: VTUR measures turbine speed via four pulse devices and sends data to the controller, triggering primary overspeed trips for safety.
2 Automatic Generator Sync & Breaker Control: VTUR manages generator synchronization and main breaker closure, improving operational efficiency.
3 Shaft Voltage & Current Monitoring: It tracks induced shaft voltage and current to assess turbine operating conditions and prevent issues.
4 Geiger Mueller Flame Detection: VTUR monitors eight flame detectors powered by 335 V DC/0.5 mA, enabling early detection of flame irregularities.
5 Primary Overspeed Trip Relays: Controls three overspeed trip relays on the TRPG board; trips can be initiated by VTUR or VPRO, ensuring redundant safety.
6 Interface with Electrical Trip Devices (ETD): TRPG uses nine relays in TMR systems (three in simplex) to operate trip solenoids, maintaining fail-safe redundancy.
Installation
1 Prepare for Installation: Power down the VME rack to ensure safety before installation.
2 Position the Board: Align and slide the board into its designated slot carefully to avoid damage.
3 Secure Edge Connectors: Press the top and bottom levers to firmly seat the board’s edge connectors.
4 Fasten the Board: Tighten the captive screws on the front panel to secure the board in place.
5 Verification and Testing: Inspect connections, power up the rack, and test the board to confirm proper operation.
Frequently Asked Questions
Q: What is IS200VTURH1BAA IS200VTURH1B?
A: IS200VTURH1BAA IS200VTURH1B is a turbine-specific primary trip board developed by GE under the Mark VI series.
Q: What diagnostic checks does IS200VTURH1BAA IS200VTURH1B perform?
A: IS200VTURH1BAA IS200VTURH1B monitors solenoid relay drivers and relay contacts for discrepancies. It identifies loss of solenoid power, abnormal flame detector voltage, and relay-related faults.
Q: How are diagnostic alarms managed on IS200VTURH1BAA IS200VTURH1B?
A: Unhealthy signals on IS200VTURH1BAA IS200VTURH1B trigger a composite diagnostic alarm. Individual diagnostic signals can be latched and reset using the RESET DIA signal when they return to a healthy state.
Q: What is the importance of terminal board connectors and their ID devices on IS200VTURH1BAA IS200VTURH1B?
A: Terminal board connectors on IS200VTURH1BAA IS200VTURH1B, such as JR1, JS1, JT1, JR5, JS5, JT5, have read-only ID devices. VTUR reads these devices containing specific board information. Mismatched data triggers a hardware incompatibility fault, ensuring compatibility across connections.
