Read Energy Central's Special Issue: "Building a 21st Century Grid." Find out what leading experts think are the greatest problems and hurdles to creating the kind of robust and reliable power delivery system we need for the coming century. "This is a serious problem. The growth of electricity demand in our economy, which over the years riveted our attention and resources to encourage newer, cleaner, and more efficient power generation capacity, has left an insufficient commitment of capital in the transmission segment of the power delivery business. Having exercised poor parental supervision, we're now paying a price." - Bob Gee, Gee Strategies and former chairman of the Public Utility Commission of Texas. Everybody's
Talking About the Problems. "I can squeeze more out of the existing system with advanced technologies. I could modernize the system and literally my view is that the system has to be integrated with other technologies such as communications and sensors, enhanced computational ability. So it becomes a living system as opposed to a dumb, dead, mechanical system." Clark Gellings, EPRI. Everybody's
Talking About T&D. "By 1984, the majority of SCADA systems were operating in a "closed" proprietary operating environment. By 1994, changes occurred as newer technology enabled broader information sharing, and as end-users began to realize and seize upon the extensive wealth of information available in the SCADA data repositories. By 2004, the control center world has largely evolved to enable access to selected operational data via secured intranet for utility and pipeline operations, engineering, metering, IS and other internal personnel, as well as to key customers." - Chuck Newton, Newton-Evans Research Company. Everybody's
Talking Generalities. "The newest measure to mitigate line sag, commercially called the Sagging Line Mitigator or SLiM, deals directly with the cause of the line sag: line elongation due to rising conductor temperature. SLiM installs in series with the line and becomes shorter as the conductor temperature rises due to high current flow and ambient conditions. SLiM maintains a nearly constant effective line length and sag within the span as conductor temperature rises. The benefits of SLiM include low cost, passivity and practically zero maintenance." - Dariush Shirohammadi and David Kopperdahl, Material Integrity Solutions. Everybody's talking . . .
