Emerson to Automate Power Plant in Northwest China

Emerson Process Management has received a $2.72 million contract to install its Ovation expert control system at Huadian Lingwu Power Plant units 3 and 4, which are the first 1,000-MW, ultra-supercritical units in China to utilize air-cooling condenser technology..

As part of its automation solution, Emerson will supply a total of 67 redundant Ovation controllers, 20 workstations and more than 70 Fisher control valves to Huadian Lingwu Unit 3 and Unit 4. At each unit, an Ovation control system will perform data acquisition as well as monitor and control the air-cooled condensers, Donfang boiler, sequence control system, electric control system, modulation control system, furnace safety supervisory system, flue gas desulfurization (FGD) system, feedwater pump turbine and balance-of-plant processes. Each Ovation system will also interface to Hitachi steam turbine controls. In addition, Emerson’s Ovation technology will monitor and control systems common to both units using multi-networking technology. All told, the Ovation control systems will manage a total of approximately 28,000 I/O points.

"We already know firsthand about the advantages of Ovation technology, based on our experience at units 1 and 2,” explained Lead Engineer Wu Lianwen, Huadian Lingwu Power Plant. “We based our decision to select Ovation for units 3 and 4 on our personal experience with the technology, as well as Emerson’s extensive expertise automating 1,000-MW, ultra-supercritical units, and their significant resources in China.”

"Emerson’s involvement at the Huadian Lingwu Power Plant demonstrates how we bring our global resources and industry-leading technologies together for the benefit of our customers,” said Bob Yeager, president of the Power & Water Solutions division of Emerson Process Management. “We are gratified by the organization’s continued confidence in Emerson’s people and technologies.”
