Functional Description

DS200GASCF1AFB is a Software PROM Set developed by GE under Mark V control system. Controllers in a power plant system utilize various types of memory, including Electrically Programmable Read-Only Memory (EPROM). EPROM is used for storing fixed memory, which is essential for the system's operation. Unlike volatile memory, which loses its data when power is turned off, EPROM retains its data permanently until it is electrically erased and reprogrammed. This characteristic makes EPROM ideal for storing critical firmware and system configuration data that rarely change.

Vibration Measurement and Protection with the Mark V

• Monitoring and Diagnostics: In systems employing Triple Modular Redundancy (TMR), any inconsistency among the inputs from the three control processors is flagged as an internal diagnostic fault message. Despite this fault, the vibration protection system continues its normal calculations, relying on the median vibration signal to maintain robust protection of the turbine.
• Proximity Transducer Inputs: Proximity transducers provide critical data on vibration, position, and key phasor inputs. The Mark V system displays essential parameters such as 1X and unfiltered vibration levels, along with the 1X vibration phase angle, directly on the operator interface's monitor. For enhanced monitoring capabilities, an optional module is available, featuring buffered BNC connectors compatible with Bentley Nevada's vibration analysis equipment, facilitating remote monitoring and analysis.
• Customizable Control Strategy: The Mark V system boasts powerful features for tailoring control strategies to suit the unique requirements of each site. Operators have the flexibility to configure one interface to interface with multiple systems or multiple interfaces to communicate with a single Mark V unit. This hierarchical control capability enables sophisticated control arrangements to be programmed on-site, particularly when multiple operator interfaces are deployed.
• Communication Links: Seamless integration with Distributed Control Systems (DCS) and remote computers is facilitated through various communication links. These include ModbusTM and EthernetTM TCP/IP links, utilizing GE Standard Messages as the application protocol. These communication options ensure seamless data exchange and interoperability with external systems, enabling comprehensive monitoring and control of turbine operations.

FREQUENTLY ASKED QUESTIONS

What is DS200GASCF1AFB?
It is a Software PROM Set developed by GE.

What is the Master Trip Circuit in the Mark V control system?
The Master Trip Circuit is a crucial component of turbine protection within the Mark V control system. It manages the inputs that trigger turbine trips and orchestrates the response from the control system.

What are the two main parts of the Master Trip Circuit?
The Master Trip Circuit comprises inputs to the Mark V and outputs from the Mark V. Inputs include hardwired or remote trip signals, while outputs dictate the system's response to these signals.

How are hardwired trip inputs connected to the Mark V?
Hardwired trip inputs, typically configured as contact open to trip, connect to the 4's relay coils within the Mark V system.
