The functions of a maglev vertical-axis wind turbine (VAWT) have been improved to allow its effective utilization at high altitudes and without the restriction of geographical locations where weak wind regimes exist. The proposed VAWT system could be erected with the minimal construction lead time and without the need for year(s) of long wind measuring and/or analysis. A Helium lift vehicle has been designed to continuously align the VAWT system to the optimal altitudes where its design wind speed exists, hence ensuring its operation at maximum efficiency at all times. The helium vehicle is fitted with a rudder, elevators, and two aircraft engines to enable its possible ascend/descend and maneuverability. The helium lift vehicle is controlled and guided by a weather station that continuously monitors the different weather indicators. The maglev VAWT system comprises a smaller VAWT that is used to excite the coil fields of the electric generator of the principal VAWT in order to reduce the power loss that usually occurs in synchronous generators. The selected size of the spherical helium lift vehicle will allow an installed capacity of the VAWT system up to 500kW. |
