New transmission technologies needed to develop a sustainable energy infrastructure

Summary form only given. This presentation discusses several new transmission technologies that are needed to develop a sustainable energy infrastructure. Technologies will be summarized and presented that show the potential to both increase the flow of power over existing lines while maintaining or even improving the reliability of the power delivered. Advanced power electronic systems and power electronic switches that can yield significantly lower cost power flow control devices, power electronic circuit breakers and fault current limiters, voltage support systems, and even power electronic transformers will be presented and discussed. In addition the advent of superconducting technologies that can also contribute to improved voltage support and long distance transport of electricity will be mentioned. In addition the advantages of current generation transmission line sag monitoring systems to increase transmission loadings while also improving reliability will be discussed.
