Functional Description

DS200DENCF1ADC is an EPROM Set designed and developed by GE. It is a part of Mark V control system. Gas Turbine Control System carries out a multitude of tasks, encompassing fuel, air, and emissions regulation. It manages the sequencing of fuel and auxiliary systems during startup, shutdown, and cooldown. Additionally, it handles synchronization and voltage matching for the generator and system while vigilantly overseeing all aspects of turbine, control, and auxiliary operations. This system also serves as a safeguard against unsafe and unfavorable operating conditions.

Control Panel Configurations

The Mark V control panel offers flexibility by being available in two primary configurations: triple modular redundant (TMR) or single modular (Simplex).

Configuration Options:

• TMR Configuration: The TMR configuration is commonly chosen for new gas turbine units. It is characterized by a high level of redundancy and resilience. In this setup, three identical control processors, referred to as R, S, and T (collectively called Q), work in unison to monitor, control, and protect the unit. These three control processors operate identically, and most of the inputs and outputs undergo a voting process to ensure accuracy and reliability.
• Simplex Configuration: The Simplex configuration is more commonly used in existing gas turbine control system retrofit applications. In this configuration, a single control processor, R, is employed. Unlike the TMR configuration, the Simplex setup does not use software-implemented fault tolerance (SIFT) technology. Furthermore, it cannot control or protect a turbine while its single control processor is taken out of service for repairs.

Compatibility:

• New gas turbine units typically opt for the TMR control panel due to the need for advanced redundancy and fault tolerance.
• Most existing gas turbine control system retrofit applications have the flexibility to choose either a TMR or a Simplex control panel, allowing them to tailor the system to their specific requirements.
• New steam turbine units have the option to be equipped with either a TMR or Simplex control panel, providing adaptability to the needs of different installations.
• Existing steam turbines can also be retrofitted with either a TMR or Simplex control panel, enabling them to benefit from the latest control technology.

Components of the Control Panel:

The Mark V control panel is composed of various cores, which house printed circuit cards and terminal boards. Cores are sheetmetal enclosures that can include stationary and movable printed circuit card holders known as card carriers. Each core can accommodate up to five printed circuit cards mounted on card carriers, along with up to four I/O terminal boards, which are printed circuit cards with high-density terminal boards. The different cores in a typical Mark V control panel include:

• Communicator processor core, C
• Protective core, P
• Power distribution core, PD
• Communicator processor digital I/O core, CD
• Control processor digital I/O core, QD1
• Optional cores that can be added to the system include a backup communicator processor, D, and additional digital I/O core(s), QD2.

The choice between TMR and Simplex configurations, along with the flexibility in core and component selection, allows users to tailor the Mark V control panel to their specific needs, whether it's for new installations or retrofit applications in gas and steam turbine units.

FREQUENTLY ASKED QUESTIONS

What is DS200DENCF1ADC?
It is a EPROM Set designed and developed by GE

What are the primary configurations available for the Mark V Control Panel?
The Mark V Control Panel is available in two primary configurations: Triple Modular Redundant (TMR) and Simplex.

What is the TMR Configuration, and for which applications is it commonly used?
The TMR Configuration is characterized by three identical control processors, denoted as R, S, and T (collectively called Q), which work together to monitor, control, and protect the unit. It is commonly chosen for new gas turbine units due to its high redundancy and fault tolerance.

What is the Simplex Configuration, and when is it typically employed?
The Simplex Configuration involves a single control processor, R. It is more commonly used in existing gas turbine control system retrofit applications. Notably, this configuration does not utilize Software-Implemented Fault Tolerance (SIFT) technology and cannot control or protect a turbine when its single control processor is taken out of service for repairs.
