FUNCTIONAL DESCRIPTION:

DS200TCEAP1BBD is a Software PROM Set manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic Gas Turbine Control Systems. The three TCEA boards used in the core are referred to as the , , and processors. These boards each bring in signals for high and low shaft speed, flame detection, and automatic synchronization. The signals are scaled conditioned and written over the IONET to the STCA board in the core via the JX1 connector located on the TCEA board in location one, (). The TCEA boards in locations three, (), and five, (), transfer their information using the JX1 and JX2 connections via .

The I/O Engine in the core uses the data from the three TCEA boards and performs a median selection on the three values and the results are transferred across the COREBUS to the Control Engine. The TCEA boards send emergency trip signals to the Turbine Trip Board (TCTG), and each TCEA board sends a trip signal to different relays. The three relays on the TCTG board perform a 2/3 vote (relay driver-level voting), and the results determine whether the TCTG board trips the unit. Each TCEA board has its own power supply and power supply diagnostics.

TCEA AUTOMATIC SYNCHRONIZING CIRCUIT:

The bus and generator voltages from the PTBA terminal board are sent through the JV connector to the TCEB board where the JMP connector transfers them to the TCEA board. Embedded software in EPROMs on the TCEA board performs speed matching and voltage matching. The TCEA board sends the permissive to close the breaker after checking for proper generator and line voltages and frequencies and that the differential between the line and the generator is within the limits set by the I/O Configuration constant. The STCA board performs a separate synchronization check function, which sends a logic signal to the TCEA board. This logic must be satisfied to enable a breaker closure.

FREQUENTLY ASKED QUESTIONS:

How is the EOB integrated into the software PROM set?

The EOB functionality is programmed into the software PROM set, ensuring seamless integration with the control system of the equipment. During the PROM set's installation or programming process, parameters related to overspeed thresholds and shutdown procedures are configured to suit the specific application requirements.

What are the benefits of having an EOB in the software PROM set?

The presence of an EOB enhances safety by proactively preventing overspeed situations, thereby reducing the risk of accidents, injuries, and equipment damage. It provides peace of mind to operators and enhances overall operational reliability.

How does a Software PROM Set differ from other memory solutions?

Unlike traditional random-access memory (RAM), which loses its data when power is removed, a PROM set retains its programmed data even when powered off. This permanence makes it suitable for storing essential boot-up routines, control algorithms, or configuration settings in embedded systems.
