How do superconductors avoid breaking Kirchoff's Voltage Law?
In the case of a wind turbine wound from superconducting wire, the current induced in the wire would create a magnetic field opposing the motion of the blades. The voltage would remain at zero* but there would be current flowing. That's ignoring the inductance of the loop of superconducting wire, which can have voltage across it if the current is changing just like any other inductance.
KVL does not apply to inductors if you think of them as  pieces of wire, only as lumped elements, and even a piece of straight wire a few mm long has some inductance (maybe 1nH).
*provided the current was less than Jc the critical current density of the weakest part of the circuit.
