Description

The GE IS200VTURH2BAC is a Vibration Transducer Interface Module engineered for the Mark VI Speedtronic™ gas turbine control system. The GE IS200VTURH2BAC acquires shaft speed signals from magnetic pickups and processes six independent analog inputs for vibration monitoring. Critical to its design are three levels of overspeed protection (control, primary, emergency) that utilize a 2-out-of-3 voting circuit on trip solenoids, ensuring fail‑safe turbine shutdown. The GE IS200VTURH2BAC also runs an automatic synchronization algorithm, monitors induced shaft voltage/current, and interfaces with up to eight flame detectors, delivering comprehensive, redundant protection for demanding industrial power generation environments.

Applications

Primary turbine protection – oversees critical functions, including overspeed prevention and trip solenoid management.
Flame detection – interfaces with up to eight Geiger‑Mueller detectors for early flame irregularity detection.
Generator synchronization – runs the auto‑sync algorithm to automate breaker closure against grid conditions.
Shaft monitoring – continuously tracks induced shaft voltage and casing current to detect electrical issues.
Condition monitoring – processes vibration signals from proximity probes and seismic sensors for rotating machinery health analysis.

Features

Ultra‑stable thermistors – provide excellent zero and span stability with minimal drift.
Three‑level overspeed protection – integrates control (closed‑loop speed regulation), primary (controller‑based), and emergency (trip solenoid activation) levels.
6 high‑impedance analog voltage inputs – accepts signals from various vibration transducers without loading the sensor.
Dual‑source trip initiation – trip commands can originate from either the VTUR or the VPRO protection processor, offering redundant safety paths.
Automatic synchronization control (auto‑sync) – runs an advanced algorithm that monitors generator and bus voltages to calculate phase, slip, and acceleration, compensating for breaker closure time delay.
Built‑in noise immunity – uses zero‑voltage crossing techniques for synchronization and phase‑locked loops (PLL) for synchronization checks to ensure reliable readings.
Up to 8 flame detector inputs – monitors Geiger‑Mueller detectors for comprehensive combustion safety.
4 high‑precision speed inputs – accepts signals from magnetic pickups (MPUs) with ±0.05% accuracy and a wide 2 Hz to 20 kHz range.
Flexible redundancy architecture – supports simplex, dual, and Triple Modular Redundancy (TMR) configurations for maximum system availability.
Real‑time diagnostic LEDs – provides RUN, FAIL, and STAT indicators for immediate board health assessment and troubleshooting.
Ruggedized construction – designed to withstand the high‑EMI and vibration present in gas turbine environments.
Backplane integration – interfaces directly with the VME backplane of the Mark VI rack for high‑speed, low‑latency data transfer.

Functions

Provides three‑layer overspeed protection – continuously measures turbine speed and signals a primary trip when thresholds are exceeded.
Executes automatic generator synchronization – monitors PT inputs, calculates phase/slip difference, and closes the main breaker via relay K25 when conditions are met.
Processes vibration and shaft signals – digitizes data from six analog voltage inputs and four speed pickups for real‑time monitoring and diagnostics.
Controls primary overspeed trip solenoids – sends trip signals to the TRPG terminal board, where 2/3 voting logic removes power from the solenoids.
Monitors flame detectors and shaft health – reads pulse currents from up to eight flame sensors and tracks shaft voltage/current levels for fault detection.
Performs synchronization checks – verifies voltage, frequency, phase, and slip against configurable limits using a phase‑locked loop technique for noise immunity.
