Advanced batteries supply ancillary services
For the power engineer, delivering an instantaneous and consistent power supply can be an elusive goal. Yet without it, grid frequency regulation is impossible. Today, frequency regulation is an ancillary service bought by the hour, the day prior to utilization, and dispensed on an as-needed basis by dispatch communiqués and provided by the ancillary service […]

Securing continuous mobile data connections
For busy staff in the field, nothing is more frustrating than having laptop computers or smart phones crash due to lost connections when those devices lose wireless coverage. Often, important data is obliterated and workers have to waste precious time reentering the lost information. The irony is that wireless data connections, which are increasingly being […]

JCP&L’s SCADA-controlled adaptive relay scheme saves 25 SAIDI impact minutes
In 2005, Jersey Central Power & Light (JCP&L), a subsidiary of Akron, Ohio – based FirstEnergy Corp., initiated a project to identify protection system improvements that could be made to proactively combat wind- and lightning-related weather events that create sustained power outages (Figure 2). JCP&L determined that these changes had the potential to improve the […]

Cooling water intake structure regulations
In the wake of a recent federal case, large power plants are off the hook for now as far as complying with the U.S. Environmental Protection Agency’s (EPA’s) 2004 rule intended to protect fish and other aquatic organisms by controlling cooling water intake practices.

Computer simulation as a NOx reduction design tool
A utility evaluated various methods of obtaining a NOx reduction of at least 30%, as required by upcoming regulations for its boiler, which originally produced 0.54 lb of NOx/million Btu at 410 MW full load. Nalco Mobotec engineers performed a computational fluid dynamics (CFD) simulation of the boiler to first understand the boiler’s combustion process and then determine the most economical method to achieve the required NOx reduction.
