Description:
The IS200TPROH1CAA is a Turbine Protection Board developed by GE.
It is part of the Mark VIe control system, where the TPRO and VPRO
systems form an integral part of the turbine control architecture,
playing crucial roles in ensuring operational safety. This section
outlines their functions and responsibilities within the system.
The board operates independently to provide essential signals for
emergency overspeed and synchronization protection.
Features:
- Overview of VPRO System: Comprising triple redundant boards, the
VPRO serves as the primary control mechanism for the emergency trip
function. It coordinates the operation of trip solenoids through
TREx terminals, ensuring swift response in critical situations.
This subsection introduces the functionalities and configuration of
the VPRO system.
- Configuration of Protection System: The protection system,
consisting of triple redundant boards, operates autonomously in a
separate module from the turbine control system. This subsection
describes the arrangement and interconnections of the boards with
the trip solenoids through TREx terminals, emphasizing redundancy
and reliability.
- Role of TREx Terminals: TREx terminals, including TREG, TREL, and
TRES, facilitate the control of trip solenoids within the
protection system. This subsection elucidates the functions and
connections of TREx terminals, highlighting their role in ensuring
the safety and integrity of turbine operations.
- Emergency Trip Functionality of VPRO: It assumes the critical
role of providing emergency trip functionality, ensuring rapid
response in emergency situations. This subsection details the
operation of VPRO in coordinating trip solenoids and implementing
emergency overspeed protection and stop functions.
- Control of Trip Solenoids: Up to three trip solenoids can be
connected between TREx and TRPx terminals. This subsection explains
the configuration and operation of trip solenoids, emphasizing the
roles of TREx and TRPx terminals in providing the necessary voltage
for their operation.
- Voting Mechanism and Relay Control: VPRO controls the operation
of trip solenoids through a sophisticated voting mechanism,
utilizing 12 relays on the TREG board. This subsection describes
the voting process and relay control, ensuring redundancy and
reliability in emergency trip functions.
- Expansion Possibilities: The system allows for expansion with the
integration of a second TREG board, which can be driven from VPRO
through J4. This subsection explores the potential for system
expansion and the integration of additional components to enhance
functionality and redundancy.
Installation:
- Wiring of Generator and Bus Potential Transformers, Analog
Inputs, and Thermocouples: Begin by wiring the generator and bus
potential transformers, analog inputs, and thermocouples to the
first terminal block on the TPRO board. This step is critical for
integrating essential sensors and inputs into the system, enabling
accurate monitoring and control of generator and bus parameters.
- Connection of Magnetic Speed Pickups: Next, connect the magnetic
speed pickups to the second terminal block on the TPRO board. These
pickups play a crucial role in measuring the speed of rotating
machinery, providing vital feedback for monitoring and control
purposes.
- Configuration of Analog Inputs: Adjust jumpers JP1A and JP1B to
configure the analog inputs according to system requirements. These
jumpers allow for selecting either a 4-20 mA or voltage input on
the first of the three analog inputs, providing flexibility in
sensor integration and signal processing.
- Verification and Testing: Once the wiring and configuration are
complete, perform thorough verification and testing of the TPRO
system. Check for proper connections, signal integrity, and
functionality of sensors and inputs. This step ensures that the
system operates as intended and meets performance requirements.
- Integration with Control System: Integrate the TPRO system with
the overall control architecture, ensuring seamless communication
and interoperability with other system components. This may involve
connecting to control panels, data acquisition systems, or SCADA.
- Commissioning and Calibration: Commission the TPRO system by
calibrating sensors, setting operating parameters, and configuring
alarm thresholds. Conduct rigorous testing under various operating
conditions to validate system performance and reliability.
Operation:
- Supply of Speed Signals: Serves the critical function of
supplying speed signals to the VPRO system for emergency overspeed
(EOS) protection of the turbine. These signals are pivotal for
detecting and responding to potentially hazardous overspeed
conditions, ensuring the safety of turbine operations.
- Provision of Generator Signals: In addition to speed signals, it
provides generator signals for backup synchronization check
protection. These signals enable the detection of synchronization
faults, ensuring that the turbine remains synchronized with the
grid or other power sources for stable and efficient operation.
- Handling Analog Inputs: TPRO is equipped with three analog
current inputs, serving various monitoring and protection purposes.
These inputs are utilized for tasks such as monitoring exhaust
over-temperature on gas turbines, providing crucial data for early
detection and prevention of overheating issues.
- Management of Thermocouple Inputs: The system also accommodates
nine thermocouple inputs, primarily dedicated to exhaust
over-temperature protection on gas turbines. These inputs enable
precise monitoring of temperature levels, allowing for prompt
intervention in case of temperature anomalies to prevent potential
damage to the turbine.
- Power Supply Arrangements: VPRO supplies 28 V DC power to TPRO to
energize the three analog input transmitters. This ensures
continuous operation of the analog input subsystem, enabling
accurate and reliable monitoring of critical parameters.
- Collaboration with VPRO: TPRO and VPRO work in tandem to ensure
comprehensive protection and control of the turbine system. While
TPRO supplies crucial signals and inputs, VPRO provides essential
power and coordination functions, ensuring seamless integration and
operation of the protection system.
