Overview
GE has supplied the "Mark" series of controls for its heavy duty gas turbines since 1968. Currently, there are thousands of analog and digital systems controlling, protecting, and monitoring units on generator and mechanical drives world-wide. With age, these systems become more difficult and costly to maintain and are often incapable of performing advanced functions to improve efficiency, reliability, emissions, etc.
Gas Turbine Control Platforms
Product Description
Today, GE offers the Mark VI and Mark VIe for direct replacement of any legacy product. Delivering the latest control and protection algorithms, our control systems reflect the lessons-learned from years of experience and current compressor and combustion technology. A variety of operator stations, communications, and gas turbine upgrades are available to modernize the complete package.
Mark I and Mark II Upgrades
These upgrades benefit from elimination of large quantities of relays and the need to recalibrate due to thermal drift. Spare parts and service are more readily available along with many new control functions that are now in software. Related systems from the same era can now be eliminated by integrating RTD monitors, synchronizing equipment, sequence of events monitors, and load compressor controls. Operators and maintenance personnel are no longer constrained by limited information available from meters, indicating lights, annunciator windows, and scarce diagnostic lights for operational decisions and locating faults.
Mark IV and Mark V Upgrades
These upgrades benefit from advances in digital technology, providing:
- Substantially more computational power to run advanced performance algorithms
- Better fault tolerance and redundancy options to improve reliability
- Modern networks with access to all data from any location
- Software tools to present and analyze the information
