Maximize the capacity of your transmission lines

Abstract

One of the most critical issues facing the electric utility industry today is determining the adequacy of transmission capacity for maximum operating conditions. Planning, protecting and operating increasingly complex and crucial transmission systems requires a comprehensive examination of the maximum load each line can safely carry during periods of peak loading. Engineering lines to a maximum safe operating temperature can be readily achieved through today's technologies. Many in the electric utility industry are now realizing that identifying low-cost analysis and upgrade solutions is a much simpler process than anticipated. The presenters, from two leading technology companies recognized nationwide, will showcase low-cost methods for determining conductor tension in existing lines. Determining limiting clearance conditions based on field-measured conductor tensions and performing "what if" scenarios for elevated operating temperatures, planners and engineers will have the information necessary to create effective cost/benefit and incremental upgrade strategies that maximize existing transmission assets. To illustrate this point, the presenters outlines case studies, which yield a significant increase in operating temperature and capacity. Clearly, leading-edge transmission companies that differentiate themselves through the use of innovative technologies and techniques will ensure their ability to prosper and survive in the volatile landscape of deregulation.
