DS200TCGG1A - Emergency Overspeed Board

SPECIFICATIONS

Part Number: DS200TCGG1A
Manufacturer: General Electric
Country of Manufacture: United States (USA)
Series: Mark V
Function: Emergency Overspeed Board

Functional Description

DS200TCGG1A is an Emergency Overspeed Board developed by GE. It is part of the GE Speedtronic Mark V control system. Emergency Overspeed is responsible for processing speed-related signals and initiating protective actions if the speed exceeds safe operating limits. It interfaces with various sensors and modules within the Mark V system to evaluate real-time speed data, and in the event of an overspeed condition, it can trigger emergency shutdowns or trips to safeguard the turbine and connected equipment.

System Features

• The Mark V Gas Turbine Control System represents the culmination of decades of proven expertise in gas turbine control technology, building on a long and successful legacy. A significant portion of this legacy involves the integration of advanced electronic and microprocessor-based techniques, which have greatly enhanced the precision, reliability, and responsiveness of turbine operations.
• The Mark V system continues this tradition by offering substantial improvements in key performance areas, including starting reliability, operational stability, and overall system availability. These enhancements are made possible through the logical evolution of the architectural innovations first introduced with the Mark IV system. The Mark V further refines these concepts to meet the increasingly demanding requirements of modern power generation and mechanical drive applications.
• One of the defining characteristics of the Mark V system is its modular and flexible architecture, which allows it to be effectively applied across a broad spectrum of turbine configurations and operational environments. Whether used in generator drive systems, mechanical drive systems, or complex industrial processes, the Mark V adapts with ease to both utility and process industry requirements.
• Designed to perform in both peaking and base load service modes, the system excels in environments where consistent performance and high availability are critical. Additionally, the Mark V emphasizes ease of operation, streamlined diagnostics, and comprehensive monitoring capabilities, making it a trusted platform for turbine operators worldwide.

FREQUENTLY ASKED QUESTIONS

What is DS200TCGG1A?
It is an Emergency Overspeed Board and is part of the GE Speedtronic Mark V gas turbine control system.

What is Triple-Modular Redundancy (TMR) in the Mark V system?
TMR is a fault-tolerant architecture where three independent control processors (R, S, T) operate in parallel. They vote on critical control decisions to ensure that the system continues functioning correctly, even if one processor fails.

Is the Mark V suitable for utility and process industries?
Yes. The system’s flexibility, modular design, and scalability make it ideal for both utility-scale power plants and industrial process environments, including mechanical drives and co-generation systems.
