It’s All About Control

Emerson’s single-platform solution to enhance reliability, streamline operations

Posted on April 21, 2014

Union Power Partners, a subsidiary of Entegra Power Group, has awarded Emerson Process Management a contract to replace aging turbine controls at one of the largest combined-cycle facilities in the U.S.

Located in southern Arkansas, U.S.A., the Union Power Station has a generating capacity of 2200 MW and comprises four individual 2x1 combined-cycle power blocks.

Emerson said the existing controls are becoming obsolete and will soon no longer be supported by the manufacturer, making maintenance and repair difficult.  The company will replace legacy controls on the power block’s GE Frame 7FA gas turbines and GE D11 steam turbine with its Ovation control technology, and the GE EX2000 systems with its Ovation generator excitation technology.

Emerson said the new controls will integrate with existing Ovation systems already controlling balance-of-plant equipment and processes, as well as Emerson’s Ovation Security Center, which streamlines the execution of cyber-security measures related to compliance with the North American Electric Reliability Council (NERC) Critical Infrastructure Protection (CIP) standards.

The contract also calls for Emerson to supply auto synchronizers. Equipment delivery will take place in October, and the first retrofitted power block is expected to be back online in December 2014.
