A wide variety of industries rely on properly functioning gas or steam turbines to provide vital services and products. Pipeline companies, paper companies and utility providers all routinely utilize turbines. The systems controlling those gas or steam turbines have become increasingly complex, as suppliers providing control systems have moved toward increasing the efficiency of all turbines.

Turbine efficiency is key to controlling industry costs. Simple turbines are not overly efficient, but over the past 30 years, increasingly effective control systems and turbine designs have been introduced, allowing efficiency to be significantly increased. When GE introduced their first electronic systems, they were a vast improvement over the mechanical and hydraulic system formerly used, but that system was still too inefficient to meet modern industry needs. Newer systems, utilizing complex functions that integrate all power island and balance of plant systems, have exponentially improved both efficiency and reliability.

The GE Mark V control system is the most recent addition to the family of control products that GE provides. The system can easily be adapted for use by many industries through the adaptation of application specific components, including a variety sensors and actuators. GE works with clients to provide a system that is tailored to provide maximum performance for the specific application. When modern gas turbine controls function properly, rapid data transfer rates between all components allow the equipment to reach efficiency levels not obtainable with older systems.

Speedtronic control cards are the heart of the system, and while reliable, they will need to be replaced at some point. Mark V replacement cards are available from several sources, which allows users to select providers who can best supply their immediate needs. While users may elect to use new OEM replacement cards, other options are available. As a rule, the cards can be repaired, and that may be a financially attractive option for many users. Refurbished cards are also available from many control suppliers. That option reduces turn around time and is still less expensive than obtaining a new OEM card.

Control card replacement options, as well the need to repair or replace other turbine components, should always be a consideration for users, as downtime must be minimized to maintain productivity levels. In the case of any GE control system, which remains the standard for gas and steam turbines, establishing a working relationship with a company providing system parts is essential for cost containment.
