Functional Description

IS200TPROH1BCB is a protective terminal board developed by GE. It is a part of the Mark VIe control system. The TPRO plays a pivotal role in providing critical signals to the VPRO (Voting Processor) board, contributing to an independent emergency overspeed and synchronization protection system. The synergy between TPRO and VPRO, along with the integration of TREx and TREG boards, forms a comprehensive and redundant emergency overspeed and synchronization protection system. This architecture ensures the reliability and safety of the turbine operation in critical situations, with provisions for independent control and backup mechanisms.

Features

• Signal Inputs from TPRO to VPRO: TPRO serves as the source for essential signals, including speed signals, temperature signals, generator voltage, and bus voltage. These signals are crucial for monitoring the turbine's operational parameters and ensuring the system's safety.
• Triple Redundant VPRO Boards: The VPRO boards are configured in a triple redundant setup, emphasizing the system's reliability. This arrangement ensures that even if one VPRO board experiences a failure, the others can seamlessly take over, maintaining the integrity of the emergency overspeed protection system.
• Independent Module for Protection System: The protection system, governed by the VPRO boards, operates independently in a separate module from the turbine control system. This isolation enhances the robustness of the emergency overspeed and synchronization protection functions.
• Control of Trip Solenoids through TREx: The trip solenoids, crucial components in the emergency stop functionality, are controlled by the VPRO boards through TREx (Turbine Relay Extension) terminal boards. These terminal boards, such as TREG, TREL, or TRES, facilitate the connection and coordination of trip solenoids.
• Cabling Configuration: The cabling between TPRO, VPRO, and TREx terminal boards is carefully configured to ensure seamless communication. The correct transmission of signals is vital for the effective operation of the emergency protection system.
• Emergency Trip Function of VPRO: The VPRO board assumes a central role in providing emergency trip functions. In case of an overspeed or other critical situations, the VPRO board initiates the emergency trip, ensuring a swift and decisive response to prevent potential damage to the turbine.
• Trip Solenoid Connection to TRPx Terminal Boards:Up to three trip solenoids can be connected between the TREx and TRPx (TRPG, TRPL, or TRPS) terminal boards. TREx provides the positive side of the 125 V dc to the solenoids, while TRPx provides the negative side. This configuration allows either board to trip the turbine, enhancing redundancy and fault tolerance.
• Control of TREG Relays: VPRO exercises control over the 12 relays on the TREG board. Nine of these relays are organized into three groups of three, forming a voting mechanism to determine inputs controlling the three trip solenoids. This voting mechanism ensures a robust decision-making process for emergency stops.
  Secondary TREG Board Driven from VPRO: A second TREG board can be driven from VPRO through J4, further enhancing the system's flexibility and adaptability to specific operational requirements.

RFQ about IS210AEPSG1AFC

What is IS200TPROH1BCB?
It is a protective terminal board developed by GE under the Mark VIe series.

What diagnostic checks does the VPRO perform on the TPRO system?
VPRO conducts comprehensive diagnostic checks on TPRO and its associated cables and input signals. These checks are designed to ensure the health and proper functioning of the overall system.

How does VPRO handle high or low limits on analog inputs?
If high or low limits on analog inputs are exceeded, VPRO triggers a fault. This proactive approach helps identify and address potential issues related to analog signal ranges, ensuring the system operates within specified limits.

What happens if any of the monitored signals becomes unhealthy?
If any one of the monitored signals, including analog inputs, experiences an unhealthy state, VPRO generates a composite diagnostic alarm labeled as L3DIAG VPROR (or S, or T). This alarm provides a consolidated indication of the health status of the monitored signals.

The EX2100e Regulator system is available in several configurations to provide control flexibility for Thyristor and Regulator systems. For small Regulator systems, two pulse-width modulated (PWM) power converter modules use Insulated Gate Bipolar Transistors (IGBT) to provide up to 35 A or 120 A nominal output. These systems can support the following applications:
• Saturable Current Transformers / Power Potential Transformers (SCT/PPT) regulator
• Brushless exciter regulator
• Direct current (dc) rotating exciter regulator

In the SCT/PPT regulator and dc rotating exciter regulator applications, the EX2100e Regulator system can de-sensitize the effect of the exciter time constant. It incorporates direct measurement of the generator field voltage and field current to enhance speed of response to system transients.

The architecture is a single control with a single Power Control Module (PCM) or dual control with dual PCM, including a customer interface sub-system, optional diagnostic local operator interface (touchscreen), optional control operator interface (COI) remote touchscreen interface, control power input module, and PCM. The PCM consists of a bridge interface sub-system, power bridge, optional ac and dc filter networks, and alternating current (ac) and/or dc isolation devices. For expanded input and output (I/O) capability, either VersaMax® or Mark* VIe control IONet I/O modules may be added.
