POWERGRID_INTERNATIONAL Volume 16 Issue 8
The Electric Power Research Institute (EPRI) has published a basic consumer guide that addresses questions about electric vehicle technology and performance. With a variety of electric and hybrid technologies now available commercially, potential buyers are looking to understand which options might best match their needs.
NERC released an industry alert on Oct. 7, 2010, identifying possible discrepancies between as-designed and as-built conditions of transmission lines. For example, the use of ruling span approximation between dead ends can lead to a discrepancy. Those discrepancies, however, can often be resolved with use of readily available technology.
As electric utilities around the world continue to pilot and implement smart grids, many are facing a pivotal question that will shape their approaches and impact the speed at which they can progress: Are our systems and databases that enable transmission and distribution (T&D) business operations smart grid-ready? More specifically, are the geographical information systems (GIS) and enterprise asset management (EAM) systems that underpin and support network operations sufficiently integrated to support and enable effective smart grid operations?
Now that the initial smart grid hype is beginning to fade, utilities, regulators, politicians and other stakeholders are closely examining the real opportunities that smart grid solutions provide. Distributed generation (DG) represents a viable benefit area.
Dry water-blocking materials for cables come in many forms, including powder, coatings, binders and tapes. In power cables, water-blocking materials have replaced mastics around the conductors and concentric wires. The benefits of using dry water-blocking materials are numerous: cost savings in manufacturing and installation, effectiveness and reduction in cable weight.
The advancements in smart grid add one major item to the power network: tons and tons of data. That data trickle comes from multiple endpoints, technologically advanced distribution equipment and newer, smarter appliances. While the utility often asks "What are we going to do with all this data?" the consumer has another question, "Are you keeping all my data safe?"
Today, utility companies are making significant progress in developing a next-generation communications network capable of supporting the smart grid. But many utility companies still struggle with how to affordably and reliably extend this communications network to 100 percent of their service territory, especially to remote substations and customer locations that are beyond the reach of primary networks.
Power utilities around the world are transforming their transmission and distribution (T&D) systems into smart grid networks. As part of this transformation, smart metering and substation automation applications are being deployed to shave demand peaks, improve efficiency and provide reliable, quality power.
The North American Reliability Corp.'s (NERC) critical infrastructure protection rules (CIP) continue to impact power utilities. That is about to change, but not lessen. It's only bound to get more detailed and restrictive as NERC CIP grows and adapts to the industry and the smart grid.
