Mark* VIe Control System

GE’s FlexEfficiency* 50 Combined Cycle Power Plant is controlled by the Mark* VIe Integrated Control System. This contemporary distributed control architecture provides a ’one system’ approach that eliminates the need for separate and disparate control systems. The result is unified, yet simplified, plant control that enables a high level of reliability and maintainability.

Simple, Yet Advanced, Control Platform

Easy to install, commission and maintain, the Mark VIe control system delivers a proven plant control system. This single platform improves a plant operator’s productivity and plant awareness with advanced diagnostic and asset management tools.

The integrated control system connects all plant systems into one high-performance, Ethernet-based, digital network. The integrated control system designed for transient modes and cyclic mission profiles where operational flexibility and reliability requirements demand peer-to-peer control communication between the gas turbine, generator and bottoming cycle controllers.

Operators benefit from a single tool to monitor, control and protect plant equipment. This creates an environment where performance is enhanced and maintenance can be proactively managed.

With advanced control techniques and embedded GE engineering models, the Mark VIe control system delivers new levels of operational flexibility. For example, operators can select from several automated start-up profiles based on the need, and then command the plant start sequence to the desired load conditions. This is ideal for responding to fluctuating industry trading, regulations and costs.
