    摘要: A high voltage direct current (DC) tether for an airborne wind turbine includes one conductor in the center of the feeder and the shielding of the feeder as a second conductor. A mechanical strength element is disposed in between the center conductor and the shielding. In this configuration, the mechanical strength element acts also as an insulator. The center conductor and the shielding can be made of aluminum or copper. The strength element can be a high strength fiber composite, woven such as VECTRAN® or SPECTRA®. The shielding is typically used as the return conductor.

    摘要: A starting system may include a wound-field electric machine with a main generator and an exciter generator. The main generator and the exciter generator may each have stator windings and rotor windings. A shorting switch may be provided for interconnecting the stator windings of the exciter generator together when power is applied to stator windings of the main generator. This may result in starting torque being produced by the exciter generator, which starting torque may be additive to starting torque produced by the main generator.
