DETECTING APPARATUS FOR DETECTING LIGHTNING STRIKE, WIND TURBINE BLADE EQUIPPED WITH THE SAME, WIND TURBINE GENERATOR, METHOD FOR DETECTING LIGHTNING STRIKE |
摘要 |
A lightning-strike detecting apparatus comprises: receptors (lightning members) that are provided at a plurality of locations on a wind turbine blade; lightning conductors that extend from these receptors to guide lightning-strike current to ground; a plurality of optical-fiber current sensors that are provided on the respective lightning conductors, detect lightning-strike current flowing in the lightning conductors, and output an optical signal; an optical signal converter that receives the individual optical signal output from these optical-fiber current sensors, converts the optical signals to the respective characteristic electrical signals, and outputs the electrical signals; and a controller that identifies the type of the electrical signal input from the optical signal converter, determines a lightning-strike spot on the basis of the type, and reports the lightning-strike spots.
