SUMMARY:Lightning Interaction with Transmission and Distribution Power Systems
DESCRIPTION:The growing use of sensitive electronic devices and the increasing demand of utility customers for stability of the power supply in the recent years have emphasized the importance of improving the reliability and power quality levels of electric systems. Although various phenomena and situations can cause disturbances on power transmission and distribution networks\, lightning is usually responsible for a significant amount of unscheduled supply interruptions and permanent damages to equipment such as distribution transformers\, as well as damages to or malfunction of sensitive electronic equipment. It is therefore essential to evaluate the lightning electromagnetic environment in order to mitigate its effects and improve the power system quality. In this lecture\, the major mechanisms by which lightning overvoltages can be produced on power transmission and distribution (medium and low-voltage) systems are explained\, the general characteristics of the overvoltages are evaluated and their dependence upon the network configuration and some of the most important ground and stroke parameters are discussed\, with examples of measured and calculated voltage waveshapes.\nSpeaker(s): Alexandre Piantini \,\nVirtual: https://events.vtools.ieee.org/m/301750
