The high altitude wind energy system (HAWES) is a highly promising research direction in the field of renewable energy

known for its features of stable power output

high capacity factor

high mobility

and environmental friendliness. Despite its enormous potential

current research and applications of HAWES technology are still in the early stages

with few demonstration projects and limited installed capacity. To address this

the paper systematically reviews and analyzes both China and international demonstration applications of HAWES technology. It places emphasis on energy capture and conversion devices in HAWES

including tether cables

generator-wind turbine units

power electronic converters (PEC)

and energy storage. A comprehensive summary and review of each component and its related control methods are provided. By combining existing wind power integration technology with high-capacity PEC equipment schemes

the paper proposes a 10-km-class high-capacity HAWES scheme utilizing medium-voltage AC power generation and medium-voltage DC power transmission technologies. Additionally

the design requirements and challenges of tether cables

permanent magnet synchronous generators (PMSG)

and PEC equipment are analyzed

and design requirements and technical routes for electrical equipment in the energy capture and power conversion fields are presented. Finally

the applicaiton prospects of the 10-km-class high-capacity HAWES is presented.
