Part No: IS215VPROH2B
Manufacturer: General Electric
Product Type: Protection VME Assembly Board
Series: Mark VI
The IS215VPROH2B is an Emergency Turbine Protection Board developed by GE. An independent emergency Overspeed protection system is provided by the Emergency Turbine Protection (VPRO) board and accompanying terminal boards (TPRO and TREG). The protection system consists of three redundant VPRO boards in a separate module from the turbine control system, which uses TREG to regulate the trip solenoids.
To install the V-type board, follow these instructions.
The major objective of the protection module, which employs three VPRO boards, is to provide emergency Overspeed (EOS) protection for the turbine. VPRO also includes backup synchronization check protection, three analog current inputs, and nine thermocouple inputs, which are primarily used for gas turbine exhaust over-temperature protection.
Six passive, magnetic speed pickups are used for speed control and Overspeed protection. The controllers keep an eye on the first three, using the median signal for speed control and primary Overspeed protection. The R8, S8, and T8 VPROs in the protection module are wired individually to the second three.
There should never be a reason for PPRO's calculated speed to diverge significantly from the primary control's predicted speed. The magnitude difference between pulse rate 1 from both PPRO and the main control is used to detect speed differences.
The VPRO has thermocouple and analog inputs, which are usually used in gas turbine applications. There are nine thermocouple inputs monitored, three of which are connected to each VPRO.
Each VPRO board comes with its own power source. Using 125 V dc from the cabinet PDM, this creates 5 V dc and 28 V dc. As a result, the complete protection module has three power supplies for maximum reliability.
The state of the VPRO front panel is indicated by three LEDs at the top. The RUN state is a flashing green, whereas the FAIL condition is a solid red. The third LED, STATUS, is ordinarily off but displays a constant orange if the board has a diagnostic alert condition.
