OverviewMark V was GE’s second generation of micro-processor based control for gas and steam turbines. Over 2,742 units shipped from 1991 to 2004 for power generation and mechanical drive applications. Today, these reliable systems are still in service but could benefit from advancements in hardware, software, and network technology.Product DescriptionGE now offers a Mark V to Mark VIe migration program to upgrade these legacy systems for heavy duty gas turbines with minimum downtime. Mark VIe processors, power supplies, and communications are installed in the existing Mark V modules and connected to the existing I/O interface. Field terminations and turbine devices are retained to minimize installation time. Operator interfaces are replaced with modern HMIs, graphics packages, configuration and diagnostics tools, and Ethernet networks. The Mark V’s communications links to plant monitoring systems are replicated and modern protocols such as OPC are available to upgrade communications. For power generation applications, a gateway is available for communication with EX2000 generator excitation systems. Also, a Digital Front End (DFE) upgrade of the control section of the exciter can be provided, which shares the same configuration and diagnostics software as the upgraded Mark V to simplify maintenance. ValueOnce completed, the upgraded control has a front-end with the same features and functions as GE’s most modern control platform with abundant compute power, flexible networks, and user friendly software tools for operators and maintenance personnel. It is compatible with major turbine enhancements now and in the future including DLN upgrades to reduce emissions. |
