Abstract: A method may involve transmitting power between a tethered aerial vehicle equipped with wind turbines for generating power and a ground station configured to interconnect the generated power to an electrical distribution network. The power may be transmitted using high voltage, high frequency AC electrical signals, and transformers at the ground station and the aerial vehicle can scale the AC voltage for use at the respective locations. Converters at the ground station and the aerial vehicle can then convert the transformed voltage to DC. The AC voltage may be transmitted through the tether at a resonant frequency of the tether based in part on an internal capacitance between multiple conductive paths on the tether.

Abstract translation: 一种方法可以涉及在配备有用于产生电力的风力涡轮机的拴系飞行器和配置成将所产生的功率互连到配电网络的地面站之间发射功率。 功率可以使用高压，高频交流电信号和地面站的变压器传输，飞行器可以缩放交流电压，以便在各个位置使用。 然后，地面站和航空器的转换器可将转换的电压转换成直流电。 AC电压可以部分地基于系绳上的多个导电路径之间的内部电容以系绳的谐振频率通过系绳传输。
