Abstract

The present invention relates to a wind turbine (1) with a wind turbine blade strain control, comprising a tower (2), a nacelle (3), a rotor (4), a hub (5), a plurality of wind turbine blades (6), a generator (7) and a controller (8). The wind turbine blades (6) comprise a root section (9), engaging the hub (5), a tip end section (10) and an intermediate section (11) between the root section (9) and the tip end section (10). The wind turbine blades (6) comprise a sparcap (12), extending between the root section (9) and the tip end section (10). The wind turbine blade (6) comprises a first electrical path (13) from the root section (9) of the wind turbine blade (6) to the tip section (10) of the wind turbine blade (6), a second electrical path (14) from the tip section (10) to the root section (9) and an electrical time-domain reflectometry device (15) for performing electrical time-domain reflectometry measurements within the first electrical path (13) and the second electrical path (14). The invention also relates to a method for determining a strain of a wind turbine blade (6).
