TCX Turbine Control System
(Steam Turbine Control with Open Hardware Architecture)

Programmable logic controllers have long been the mainstay for industrial control applications, but have been largely ignored when it comes to steam turbine control. MD&A's TCX turbine control system has embraced PLC flexibility. Utilizing software that is adaptable to most popular PLC platforms, TCX gives power producers control alternatives previously unavailable in proprietary systems. Unlike other manufactures, MD&A provides a wide range of choices in PLC hardware, operator station hardware and human-machine interface software.

The TCX system includes all necessary functions for replacement of any OEM electro-hydraulic or mechanical-hydraulic system, regardless of steam valve configuration.

Basic functions include:

• Speed Control
• Load Control
• Load Rejection Protection
• Flow Characterization
• Pre-warming
• Protective System Testing

Upgrade Affordably:

There is more to upgrading than simply replacing hardware with newer technology. In order to be a true upgrade, control hardware replacement should increase reliability and maintainability and be cost effective. TCX brings all of this together in a system that incorporates state of the art control technology, integrates with existing control platforms familiar to your personnel and does it all at a fraction of the cost of proprietary systems.
