GE IS200TPROH1B IS200TPROH1BBB Emergency Protection Terminal Board

IS200TPROH1BBB Emergency Protection Terminal Board

The Emergency Protection (TPRO) terminal board provides the VPRO with speed signals, temperature signals, generator voltage, and bus voltage as part of an independent emergency overspeed and synchronization protection system. The protection system consists of triple redundant VPRO boards in a module separate from the turbine control system, controlling the trip solenoids through TREx (TREG, or TREL, or TRES). TPRO supplies inputs to all three VPRO boards. The following figure shows the cabling to VPRO from the TPRO and TREx terminal boards. 

The VPRO board provides the emergency trip function. Up to three trip solenoids can be connected between the TREx and TRPx (TRPG, or TRPL, or TRPS) terminal boards. TREx provides the positive side of the 125 V dc to the solenoids and TRPx provides the negative side. Either board can trip the turbine. VPRO provides emergency overspeed protection and the emergency stop functions. It controls the 12 relays on TREG, nine of which form three groups of three to vote inputs controlling the three trip solenoids. A second TREG board may be driven from VPRO through J4.

The following figure shows how the VTUR and VPRO boards share in a gas turbine protection scheme. Both detect turbine overspeed, and either one can independently trip the turbine using the relays on TRPG or TREG.
