Analysis of Transient Phenomena Due to a Direct Lightning Strike on a Wind Energy System

This paper is concerned with the protection of wind energy systems against the direct effects of lightning. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded as a serious problem. Nevertheless, very few studies exist yet in Portugal regarding lightning protection of wind energy systems using numerical codes. A new case study is p...

Oscillation Phenomena in Isolated High Voltage Networks Caused by Lightning Strokes

Isolated networks are common practice for operating high voltage networks up to a small earth fault current defined by standards. The reason for choosing this type of network are the saving of the arc suppressing coils by coexistence of a self-healing grid in case of an earth fault. During the starting up of a 110-kV-isolated network long-time measurement were installed. During these measuremen...

Lightning Discharge and Fundamentals of Lightning Protection

A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...

Lightning Protection

Lightning causes deaths, injuries, damages, and significant costs and losses around the world. The global lightning flash rate is in the range of 40 to 100 lightning flashes per second, of which about 30 % are cloud-to-ground flashes. The development of theoretical and experimental researches is crucial for a better understanding of the physical phenomenon and for the characterization of lightn...
