There are more than 50 types of transmission lines in use, with even more in the R&D stage. The goals are reductions in line loss and line faults and greater overall grid reliability and efficiency. An increasing number of transmission line applications incorporate high-temperature superconducting technologies. New types of composite conductors are being developed to retain their strength and be more resistant to degradation at high temperatures. What’s more, this sector is seeing some exciting new wide-area management systems (WAMS) and other applications built on top of data from synchrophasors. Some are even proposing an “air traffic control system” for the national grid. Keep up to date with changing transmission technologies by scrolling down.

Electric Power Research Institute (EPRI) researchers have an ongoing effort to research and develop sensor technologies and the associated infrastructure needed to aid utilities in addressing an aging transmission fleet, as well as to increase the capacity of existing assets, and help develop the next generation of equipment and technologies. Research and development efforts are underway in the following areas: Application of Sensor Information; Sensor Developments; Communication and Sensor Data Collection; Security; Power Harvesting and Algorithms and Data Visualization. In this white paper a review of these areas, from sensor applications to visualization, is described for transmission lines and substations. |
