Product Description
IS200VTURH1B is a primary turbine protection plate designed by GE for the Mark VI system. Mark VI is one of the various gas/steam turbine management systems released by GE as part of the “Speedtronic” series. MKVI is built using a TMR (Triple Modular Redundancy) architecture and has a connected HMI (Human Machine Interface) that allows users to access turbine data from a central location.
IS200VTURH1B provides multiple functions, including monitoring the induced shaft current/voltage (issuing an alarm for excessive levels), measuring turbine speed to generate a main overspeed trip, and controlling the three main overspeed trip relays belonging to the TRPx terminal board. The committee is also responsible for monitoring eight Geiger Muller flame detectors in gas turbine applications.
This component has a single slot panel with three LED indicators and a connected cable connector (J5). Three screw connectors connect the panel to the PCB.
PCB is composed of over sixty integrated circuits, thirteen transistors, hundreds of capacitors and resistors, as well as diodes and inductor coils.
The board contains two backplanes, a multi-position female plug for connecting the daughter board, and various connectors made of conductive points and wiring.
The card includes a TRPx board that drives three trip solenoid valves, accepts eight flame detectors, and stores the pulse rate in a digital circuit. VTUR detects high voltage and checks the integrity and continuity of the circuit.
Four passive magnetic velocity inputs with a frequency range of 2 to 20000 Hz are connected to the VTUR interface. The circuit sensitivity allows the use of passive sensors on 60 gears to detect 2-RPM rotational gear speed to determine if the turbine has stopped (zero speed). If automatic turning gear engagement is enabled in turbine control, this signal initiates turning gear operation.https://www.weikunfadacai1.com/
Function Description
The following are the functions of the Turbine Primary Protection (VTUR) board:
Four passive pulse rate devices measure turbine speed and send signals to the controller, triggering the main overspeed trip.
It automatically synchronizes the generator and closes the main circuit breaker.
Monitor the voltage and current induced by the shaft.
In gas turbine applications, monitoring eight Geiger Mullers ® Flame detector.
The detector needs an external power supply of 335 V dc and 0.5 mA to connect to the TRPG.
Control the three main overspeed trip relays of the TRPx terminal board.
The trip signal is generated by the controller and transmitted to VTUR, which is then transmitted to TRPx to trip the emergency solenoid valve.
VTUR or VPRO can drive the turbine overspeed trip. TRPx has nine magnetic relays that can communicate with three electrical tripping devices (trip solenoid valves) (ETDs). In TMR systems, nine relays are used, while in simplex systems, three are used.
Interface between the main trip solenoid valve and the main trip solenoid valve
The controller calculates the typical main overspeed trip and then sends it to the VTUR, and then to the selected main trip terminal board. TRPx has a relay connected to ETD. The main and emergency sides of the ETD interface are usually composed of TRPx and Emergency Trip Board (TREx). Each TRPx/TREx combination can drive up to three ETDs in the VTUR.
VTUR supports the following trip boards:
TRPG is designed specifically for gas turbines and works in conjunction with the TREG board to provide emergency braking.
TRPS is used in small and medium-sized steam turbine systems and, in conjunction with the TRES board, provides emergency shutdown function.
TRPL is designed specifically for large steam turbine systems and operates in conjunction with TREL boards in emergency situations.
Fast overspeed trip
In specific situations where a faster overspeed trip system is required, the VTUR fast overspeed trip algorithm can be enabled. The system uses a speed measurement algorithm that uses the calculation of predetermined gears.
