FUNCTIONAL DESCRIPTION:

DS200GASCF1BGD is a Software PROM Set manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Control Systems. The Mark V system represents a significant advancement in turbine automation technology, resulting from decades of continuous improvement and experience spanning over 40 years. A notable aspect of this progress is the extensive use of electronic control technology, accounting for more than 80% of the system's evolution. This digital implementation of automation techniques builds upon a rich history of innovation and adaptability, encapsulating the collective knowledge gained from years of effectively managing turbines, adapting to changing requirements, and harnessing electronic control systems' capabilities.

• The Mark V TMR control system incorporates a remarkable technology called software-implemented fault tolerance (SIFT) to ensure the reliable operation of its control processors. This technology is a fundamental element of its robust and fault-tolerant design.

• In the SIFT framework, each control processor within a TMR (triple modular redundant) control panel independently evaluates control and protection functions based on separate inputs. The three control processors in the system individually assess the inputs and collectively make decisions based on a voting mechanism.

• The key aspect of this approach is that if one control processor misinterprets an input, its erroneous value is overridden by the consensus of the other processors. To illustrate this, let's consider an example: A logic signal, which can represent either a logic "0" or a logic "1," is generated by a pressure switch that monitors lube oil pressure.

• This signal is transmitted to each of the three redundant processors within the TMR control panel through separate I/O communication networks (IONETs). Each processor interprets the signal independently, generating a pre-voted value.

• These pre-voted values are then shared with the other two processors via a single data exchange communication network (DENET). Subsequently, each processor performs a two-out-of-three "vote" on the logic signal's value and uses the majority-voted value in its control and protection algorithms and sequencing.

• This collective decision-making process ensures that a failure in one processor does not result in a turbine shutdown signal being triggered. In the event of a voting discrepancy, a diagnostic alarm is raised.

FREQUENTLY ASKED QUESTIONS:

What is a Data Exchange Communication Network (DENET)?

A Data Exchange Communication Network, or DENET, is a system or infrastructure that facilitates the exchange of data or information between different components or devices within a networked environment. It enables the seamless transfer of data for various purposes, including control, monitoring, and coordination.

What are the advantages of using I/O Communication Networks?

The benefits of I/O Communication Networks include real-time data exchange, reduced wiring and cabling, improved scalability, enhanced system flexibility, and the ability to monitor and control devices remotely.

What is Software-Implemented Fault Tolerance (SIFT)?

Software-Implemented Fault Tolerance, or SIFT, is a technology used to enhance the reliability and fault tolerance of software systems. It involves implementing mechanisms within software to detect and recover from faults or errors without relying solely on hardware redundancy.
