1. A lightning detection system, comprising:

  • a plurality of sensing devices configured to generate non-acoustic sensor signals representative of one or more working state parameters of an object;

    a lightning signal processing subsystem configured to;

    combine the sensor signals representative of the one or more working state parameters received from the plurality of sensing devices to generate a composite signal;

    extract noise signals from the composite signal;

    compare the extracted noise signals with one or more lightning signal profiles to determine the existence of lightning noise signals in the extracted noise signals; and

    generate an output indicative of a lightning detection event, the detection based on the comparison;

    wherein the object comprises a wind turbine, a tower, or an aircraft; and

    wherein the one or more working state parameters of the object comprise wind speed, wind direction, rotations per minute, stress, temperature, generation winding, vibration in blades, vibration in tower, power measurement, twist in power cable of a generator, or combinations thereof.
