Available in PDF, EPUB and Kindle. Book excerpt: Several concepts of lightning accommodation systems for wind-driven turbine rotor blades were evaluated by submitting them to simulated lightning tests. Test samples representative of epoxy-fiberglass and wood-epoxy composite structural materials were submitted to a series of high-voltage and high-current damage tests. The high-voltage tests were designed to determine the strike points and current paths through the sample and the need for, and the most proper type of, lightning accommodation. The high-current damage tests were designed to determine the capability of the potential lightning accommodation system to sustain the 200-kA lightning current without causing damage to the composite structure. The observations and data obtained in the series of tests of lightning accommodation systems clearly led to the conclusions that composite-structural-material rotor blades require a lightning accommodation system; that the concepts tested prevent internal streamering; and that keeping discharge currents on the blade surface precludes structure penetration. Induced voltage effects or any secondary effects on the integral components of the total system could not be addressed. Further studies should be carried out to encompass effects on the total system design.

Available in PDF, EPUB and Kindle. Book excerpt: The chances of lightning damage to wind turbines is increasing as these machines become larger and more numerous on individual sites. In contrast to the wind turbines, large photovoltaic (PV) power plants ranging from 100 kW to multimegawatts are still a few meters high, although there are a few tall PV plants which are secured on pedestals, with heights ranging from 5-20 meters. This study reviewed current knowledge on lightning and lightning protection methods on wind turbine and PV power plants; reviewed published data on lightning stroke damages to wind turbine and PV power plants; and provided a critical assessment and recommendations.
