Functional Description

187B8175G2L070 is a GE Component designed and developed by General Electric. It is a part of turbine control system. The control system prioritizes maintaining turbine operation under varying conditions, ensuring reliability even during failures. It incorporates advanced mechanisms to optimize fuel flow and temperature control, balancing performance with safety.

System Features

• The control system is designed to minimize machine shutdowns caused by control system failures.
• To achieve this, a high degree of redundancy is integrated, ensuring the turbine continues operating even if one part of the control system fails.
• Failures in redundant systems are annunciated while the turbine remains operational, maintaining process continuity.
• In areas where full redundancy is impractical, certain functional systems act as backups for others.
• For instance, the temperature control system takes over turbine control in the event of a speed control failure, ensuring uninterrupted operation.
• The primary design objective is to ensure turbine operation despite control system failures.
• This approach recognizes the financial and operational costs of process interruptions and shutdowns, emphasizing resilience and reliability in turbine control.
• At the heart of the control system is the speed governor, which commands the fuel control system to regulate the fuel flow to the turbine.
• The speed control operates through a minimum-value gate, working in conjunction with Temperature limit inputs, Startup scheduling parameters. These inputs ensure the gate outputs the appropriate commands to maintain stable and efficient turbine operation.
• The system's redundancy ensures operational continuity, with each failure triggering a backup mechanism or control shift to a secondary system.
• Functional systems like temperature control provide seamless transitions during control failures, reducing downtime and protecting system integrity.

Frequently Asked Questions

What is 187B8175G2L070?
It is a GE Component developed by GE.

What is the main function of this component in a turbine control system?
The component serves as part of a control system designed to manage turbine operations, with a focus on minimizing machine shutdowns caused by system failures. It regulates fuel flow via a speed governor, ensuring proper turbine functionality even during control system faults.

How does the system ensure operational reliability?
The control system uses redundancy to maintain functionality during component failures. If one redundant system fails, annunciation occurs, and the turbine continues running under the remaining systems. In areas where redundancy isn’t fully practical, functional backups are provided, such as temperature control taking over if speed control fails.

What is the role of the speed governor?
The speed governor is the central element of the control system, commanding the fuel control system to provide the correct fuel flow to the turbine. It works alongside inputs like temperature limits and startup schedules, ensuring stable and efficient operation.
