FUNCTIONAL DESCRIPTION:
IS200VTURH2BAC 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. Turbine overspeed protection is available in three levels, control, primary, and emergency. Control protection comes through closed-loop speed control using the fuel/steam valves. Primary overspeed protection is provided by the controller. The TTUR terminal board and VTUR I/O board bring in a shaft speed signal to each controller where they are median selected. If the controller determines a trip condition, the controller sends the trip signal to the TRPG terminal board through the VTUR I/O board. The three VTUR outputs are 2/3 voted in three-relay voting circuits (one for each trip solenoid) and power is removed from the solenoids. The following figure shows the primary and emergency levels of protection.
AUTOMATIC SYNCHRONIZATION CONTROL IN VTUR (K25):
VTUR runs the auto-synch algorithm. Its basic function is to monitor two Potential Transformer (PT) inputs, generator and bus, to calculate phase and slip difference, and when armed (enabled) from the application code, and when the calculations anticipate top center, to attempt a breaker closure by energizing relay K25. The algorithm uses the zero voltage crossing technique to calculate phase, slip, and acceleration. It compensates for breaker closure time delay (configurable), with self-adaptive control when enabled, with configurable limits. It is interrupt-driven and must have generator voltage to function. The configuration can manage the timing on two separate breakers.
SYNCHRONIZATION CHECK IN VPRO (K25A):
The synch check algorithm is performed in the VPRO boards. Its basic function is monitoring two Potential Transformer (PT) inputs and calculating generator and bus voltage amplitudes and frequencies, phase, and slip. When it is armed (enabled) from the application code, and when the calculations determine that the input variables are within the requirements, the relay K25A will be energized. The above limits are configurable. The algorithm uses the phase lock loop technique to derive the above input variables and is therefore relatively immune from noise disturbances.

What is the automatic synchronization control function (VTUR - K25)?
The automatic synchronization control function monitors generator and bus voltages to calculate phase and slip differences. When enabled, it attempts to close the breaker by energizing relay K25. It uses zero voltage crossing techniques and compensates for breaker closure time delays.
What is the synchronization check function (VPRO - K25A)?
The synchronization check function calculates generator and bus voltage amplitudes, frequencies, phase, and slip. When enabled and if the parameters meet specified limits, relay K25A is energized. It uses phase-locked loop techniques to ensure accurate synchronization.
