SYSTEM FOR MONITORING THE CONDITION OF ROTOR BLADES AT WIND TURBINES |
摘要 |
Some examples relate to a system for monitoring the condition of rotor blades at wind turbines. A plurality of sensor nodes can be coupled to a rotor blade. A respective at least one sensor can be present at the individual sensor nodes for the spatially resolved detection of vibrations and/or acoustic waves of the rotor blade and the sensor nodes can be connected via optical fibers to a central supply and reception unit. A light source can be present at the central supply and reception unit and electromagnetic radiation can be conducted from it via an optical fiber to a photovoltaic converter with which the received electromagnetic radiation can be converted into electric energy. The electric energy can be utilized.
