Control technology provided to power plant
Exelon selected Emerson's Ovation technology to upgrade the turbine and balance-of-plant controls at their Baltimore power plant.
As part of a $30 million project to update the plant, Exelon Generation selected Emerson to replace its outdated turbine and balance-of-plant controls with its Ovation technology at the Westport 5 Generating Station in Baltimore, Maryland. Emerson completed the project within a compressed schedule of roughly six months. This timeframe – half the time a project of this scope would typically take to complete – was necessary in order for the unit to be available by June 1, 2012, to meet peak summer demand.
As part of this turnkey project Emerson also installed eight gas-fuel modulation valves, 16 gas-fuel stop valves and eight gas-fuel vent valves. Replacing these valve trains was a key component of the upgrade, as performance of the gas valve trains is critical for maintaining frequency and optimal operation of the unit. Emerson engineered and designed unique logic for load sharing eight engines on one combustion turbine generator. The blending of each turbine’s controls quickly stabilizes plant operation to maintain 60 Hz frequency. In addition to improved availability achieved by being able to quickly and consistently reach full load, the Ovation system also contributes to tighter exhaust temperature control, which helps prolong equipment life and contributes to safer operation of the unit.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
