Overview
Currently, there are thousands of analog and digital systems controlling, protecting, and monitoring units on generator and mechanical drives worldwide. With age, these systems become more difficult and costly to maintain and are often incapable of performing advanced functions to improve efficiency, reliability, and performance.
Steam Turbine Control Platforms
Product Description
Today, GE offers the Mark VI and Mark VIe for direct replacement of any legacy product. They come with the latest control and protection algorithms reflecting the lessons-learned from years of experience. For combined cycle plants, the same control can be used for the gas turbines, steam turbines, HRSGs, duct burners, and balance of plant. For large steam applications, the feedwater control system, including the feed pump turbine controls can be integrated with the main unit controls, either in the same controllers or in separate controllers with peer-to-peer communications. A variety of operator stations, communications, and mechanical upgrades are available to modernize the complete package.
Value
Whether you have an old MHC control, analog EHC control, or early generation, and digital EHC control, there are significant benefits to an upgrade. Besides the readily available spare parts and service, modern controls have virtually unlimited flexibility for additional functions, integration of remote instrumentation, controls for driven load equipment, and add incremental redundancy where it is most needed. 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.
