FUNCTIONAL DESCRIPTION:
IS200VTURH1BAB is a Vibration Transducer Interface Module manufactured and designed by General Electric as part of the VI Series used in GE Speedtronic Gas Turbine Control Systems. The system measures turbine speed using four passive pulse rate devices and relays the signal to the controller, which initiates the primary overspeed trip. It enables automatic generator synchronization and manages the closure of the main breaker. Additionally, it monitors induced shaft voltage and current, as well as eight Geiger-Mueller flame detectors used in gas turbine applications. These detectors are linked to the TRPG and operate on a 335 V DC, 0.5 mA supply from an external source.
The controller manages three primary overspeed trip relays located on the TRPG terminal board. When the trip signal is generated, it is transmitted to VTUR and subsequently to TRPG, triggering the emergency solenoids. Overspeed trips can originate from either VTUR or VPRO. The TRPG unit features nine magnetic relays for interfacing with three trip solenoids, referred to as Electrical Trip Devices (ETD). In Triple Modular Redundant (TMR) systems, nine relays are employed, while simplex systems utilize three.
OPERATION:
In a simplex application, turbine speed can be measured using up to four pulse rate signals. The generator and bus voltages are connected to VTUR for automatic synchronization, working alongside the turbine controller and excitation system. TTUR includes permissive generator synchronizing relays and manages the main breaker relay coil 52G. Shaft voltage is captured with brushes and monitored along with the current to the machine casing.
An interface supports four passive magnetic speed inputs with a frequency range of 2 to 20,000 Hz. With passive pickups on a sixty-tooth wheel, the circuit sensitivity enables the detection of a 2-RPM turning gear speed, allowing for the identification of turbine stoppage (zero speed). If the turbine control includes automatic turning gear engagement, this signal activates the turning gear operation.
PRIMARY TRIP SOLENOID INTERFACE:
The controller calculates the normal primary overspeed trip, which is then transmitted to VTUR and subsequently to the selected primary trip terminal board. TRPx contains relays that interface with the electrical trip devices (ETD) and usually operate alongside an emergency trip board (TREG), forming the primary and emergency interfaces to the ETDs. PTUR can support up to three ETDs powered by each TRPx/TREx combination, with various trip boards available through VTUR.
TRPG is designed for gas turbine applications and works in tandem with TREG for emergency trips. TRPS caters to small and medium steam turbine systems and is managed by the PTUR I/O pack, while TRPL is intended for large steam turbine systems, also controlled by the PTUR I/O pack for emergency scenarios. Additional trip boards are under development for specific applications. To facilitate trip board functionality, VTUR offers several discrete inputs to monitor signals, including trip relay positions, synchronizing relay coil activation, and ETD power status.
