ON THE COVER
NASA's Solar & Heliospheric Observatory (SOHO) satellite was launched in 1995 to
study the sun from " its deep core to the outer corona and the solar wind. " This image
shows a huge, handle-shaped gas cloud of " relatively cool dense plasma (only 80,000K)
suspended in the Sun's hot, thin corona. " The temperature of the corona is typically
above 1 million K. Source: NASA
COVER STORY
ASSET MANAGEMENT
24 The Great Solar Storm of 2012?
A variety of U.S. federal agencies are concerned about the potential for greater-than-usual
solar storm activity-and resulting massive power grid disruptions-over
the next few years. Contingency planning for such high-impact,
low-frequency events is difficult under the best conditions. What's more worrisome
is that nobody is taking responsibility for leading the charge to develop a
comprehensive disaster preparedness plan.
SPECIAL REPORT
INSTRUMENTATION & CONTROL
30 Increasing Generation Ramp Rate at Morgantown Generating Station's CoalFired
Units
The first article in this special section, developed in partnership with the ISA Power
Industry Division, looks at how one Maryland plant countered the negative effects
of four decades of changes in operating conditions while retaining the operational
gains. The secret to ramping up unit ramp rates was an innovative combination of
technologies and techniques.
36 I&C Update on Plant Vogtle Units 3 and 4
All eyes in North America are on developments at the first nuclear plant to be built
in decades on the continent. One obvious difference in this next-generation plant
is the use of digital controls. From human factors engineering to cyber security to
the new-to-nuclear challenge of electromagnetic interference, here's how the team
is tackling the issues raised by a new controls regimen with new technologies and
old-fashioned common sense.
40 New Tools for Diagnosing and Troubleshooting Power Plant Equipment Faults
The Electric Power Research Institute is working on a project that will take the deluge
of plant process, monitoring, and diagnostic data and put it into an intelligent and
searchable database. Drawing on that database, a new software tool will then perform
anomaly interpretation, diagnosis, and condition assessment more effectively
than has been possible in the past.
44 Automated Exhaust Temperature Control for Simple-Cycle Power Plants
Developing control strategies for exhaust gas temperature is challenging because
the plant must comply with emissions requirements while maximizing performance
of the oxidation and reduction catalysts. Three strategies for balancing those concerns
by injecting tempering air are considered in this article.
