With nearly 60 years of legacy experience, GE Vernova’s Mark VIe Distributed Control System (DCS) is engineered for the evolving demands of the energy landscape. As an OEM for gas turbines, steam turbines, generators, and Heat Recovery Steam Generators (HRSGs), we provide a fully integrated control system that enhances startup performance, operability, reliability, protection, and availability across the entire plant.
Streamlined operations and maintenance
• Seamless coordination between turbines, generators, HRSG’s and balance of plant (BOP) enhances system stability and efficiency delivering a proven up to 3.9% increase in plant availability.
• Deep integration in design philosophies, standardized alarms, graphics and diagnostics tools improve plant-wide monitoring and response.
• Single controls platform reduces burden of training operators on multiple systems, and unifies Sequence of Events Data for faster diagnostics, troubleshooting and root cause identification.
• Single integrated control system configured with the OEM of the power generation equipment improves flexibility of plant to adjust to changes in operating premise.
Why choose the Mark VIe?
Rather than depending on external interfaces and middleware, the Mark VIe DCS provides end-to-end control from a single platform that simplifies systems upgrades and future operational adjustments—helping operators seamlessly adapt to changing plant operational needs including grid requirements, interconnection needs, and industrial process demands without costly overhauls.
The Mark VIe integrated control system provides a consistent, unified system that simplifies operations, troubleshooting, and maintenance across the full system lifecycle.
Key benefits of the Mark VIe
• Seamless OEM integration: A unified control system developed for gas turbines, generators, HRSGs, BOP, and integrated safety systems using the Mark VIeS Functional Safety System.
• Simplified future upgrades: A single, fully integrated plant control system that supports lifecycle management, making it easier to adapt to grid and interconnection changes.
• Enhanced startup, operability and reliability: Faster response times, improved performance, and increased uptime through an integrated controls approach.
• Developed for dynamic conditions: Improves startup sequences, more resilient to transient events (like grid frequency response) and upset conditions, accelerates recovery to stable operations following plant events.
• Modular architecture: Add or upgrade components seamlessly, extending system life without a full replacement reducing O&M expenses.
• Scalability: Adapt and expand your system as operational needs evolve over its lifecycle including the flexibility to allow simplex, dual,triple redundant or SIL 3 enabled controllers and IO on the same integrated system.
• Integrated cybersecurity solutions: Safeguard all operational assets to protect against evolving threats and help ensure stability and predictability.
• Native third party communication capabilities reduce the need for gateways: Including EGD, Profinet, Profibus DP, Foundation Fieldbus, Modbus, IEC 61850, IEC 60870-5-104, and HART.
• Application expertise: Deep domain knowledge in plant operations and capabilities to create high fidelity simulations during plant development reduces risk and schedule during plant commissioning phase.
Broad Applications
The Mark VIe DCS excels in critical infrastructure plants across a wide range of applications:
• Power generation: Gas turbines, steam turbines, generators, and HRSG/BOP controls across simple cycle, combined cycle, steam tail, and cogeneration systems.
• Industrial operations: Oil & Gas compression, smelting plants, desalination facilities, liquefaction, carbon capture, and gasification plants.
• Renewable energy: Wind turbines, hydro plants, integrated solar systems, and battery hybrid solutions.
• Specialized facilities: Nuclear power stations, subsea equipment, and other high-reliability environments.
GE Vernova’s Mark VIe DCS leverages decades of expertise and advanced technology to deliver a unified solution for enhanced plant operability, reliability, and efficiency. With a track record of success managing power generation around the globe, it can provide the confidence and adaptability needed for the future of energy.
