The $\text{DS200TCQEG2A}$ board is installed within one of the redundant control cores ($\text{R, S, or T}$) of the Mark $\text{V}$ system. It serves as a dedicated processing interface for crucial turbine data.

1. Signal Conditioning and Data Acquisition

  • Vibration and Proximitor Inputs: Its most critical function is to process high-speed signals related to the mechanical health of the turbine. This includes signals from proximity probes (Proximitors) and vibration sensors that monitor the axial and radial displacement, speed, and overall vibration levels of the high-speed rotating shafts.
  • Speed Signals: It helps process pulse rate inputs for certain speed signals (e.g., from magnetic pick-ups or $\text{TTL}$ sensors) that are essential for accurate turbine control and overspeed protection.
  • Signal Scaling: It scales and conditions these raw signals, ensuring they are accurately represented before being transmitted to the main control processor ($\text{TCQA}$ board) for use in the control algorithms.

الوصف

The GE DS200TCQEG2A is an I/O Processor Board, also known as a TCQE (Turbine Control Q/R/S/T Core Card) board, designed for the GE Mark V Speedtronic Turbine Control System.

This specific part number, with the G2 revision and the E designation, indicates it is tailored for use with the LM6000 Series Aeroderivative Gas Turbines. The DS200TCQEG2A is a newer revision (G2) of the board that performs the same critical functions as the G1A version, likely incorporating design updates, component changes, or minor functional improvements.

🚀 Primary Function and Application

The $\text{DS200TCQEG2A}$ board is installed within one of the redundant control cores ($\text{R, S, or T}$) of the Mark $\text{V}$ system. It serves as a dedicated processing interface for crucial turbine data.

  • Vibration and Proximitor Inputs: Its most critical function is to process high-speed signals related to the mechanical health of the turbine. This includes signals from proximity probes (Proximitors) and vibration sensors that monitor the axial and radial displacement, speed, and overall vibration levels of the high-speed rotating shafts.
  • Speed Signals: It helps process pulse rate inputs for certain speed signals (e.g., from magnetic pick-ups or $\text{TTL}$ sensors) that are essential for accurate turbine control and overspeed protection.
  • Signal Scaling: It scales and conditions these raw signals, ensuring they are accurately represented before being transmitted to the main control processor ($\text{TCQA}$ board) for use in the control algorithms.

2. System Integration

  • LM6000 Specific: The ‘E’ in the part number indicates it is configured for the LM6000 gas turbine, a highly efficient aeroderivative model. The board’s conditioning and scaling circuits are specifically calibrated for the sensors and operational ranges unique to this gas turbine series.
  • Interface: It connects directly to a corresponding terminal board (like the $\text{TBQE}$ board) where the field wiring from the turbine sensors is terminated.

3. High Reliability

As part of the Mark $\text{V}$‘s Triple Modular Redundancy ($\text{TMR}$) architecture, the $\text{DS200TCQEG2A}$ ensures that three independent signal paths are constantly monitoring the critical parameters. This redundancy is vital for high-availability systems like gas turbines, allowing the control system to detect and isolate a faulty signal without shutting down the equipment.

This board is considered an essential component for the safe, reliable, and high-performance operation of an $\text{LM6000}$ unit controlled by a $\text{GE Mark V}$ system.
