Lightning Protection for Buildings Energized by Renewable Energy Sources

摘要

Hybrid Renewable Energy Systems (HRESs) use renewable energy sources such as wind, hydrogen, solar etc. simultaneously. In recent years, increase in oil prices, running out fossil fuel reserves and their irreparable harmful effects and political instabilities in the regions of energy sources have been accelerated to make on studies on the renewable energy systems, especially in rural areas and developing countries where it is usually difficult to have access to the national electricity grid [1]. Recently, fuel cells using hydrogen as a fuel have been also used in the form of small modular systems [2]. In energy systems, protection must be taken into consideration against lightning strikes. It is highly possible that a strike may cause damages in expensive system components and/or human lives. Effective protection of objects and their contents against direct lightning strikes requires estimation of lightning threat [3]. Lightning protection theory was and is formed at the junction of sciences of high voltage equipment, geophysics and meteorology [4]. In typical high voltage substation are present electronic devices. They are very sensitive for any transient state especially for transients caused by lightning strike [5].
