SYSTÈME DE DÉTECTION ET D'ÉVALUATION DE FOUDRE ET PROCÉDÉ DE DÉTECTION D'EMPLACEMENT DE FOUDROIEMENTS SUR UNE PALE D'ÉOLIENNE

摘要

The lightning detection system (1) includes a lightning ground conductor (3) of a turbine blade (2), several lightning receptors (4, 6, 7) connected to the lightning ground conduc- tor, and several individual lightning detectors (8, 9) measuring a lightning parameter indicative of the magnitude of a lightning current. A main ground conductor lightning detector (10) measures a magnitude of any lightning current leaving the blade through the lightning ground conductor. Each individual lightning detector includes an individual sensor element, an individual microprocessor, an individual memory storage, an individ- ual wireless communication module, and an individual power supply including a battery and a power harvesting device. The system includes a central wireless communication module (18) communicating directly with one or more of the individual wireless commu- nication modules, and each individual wireless communication module communicates directly with at least one of the other individual wireless communication modules and/or the central wireless communication module.
