NºPublicación: US2018195345A1 12/07/2018

Solicitante:
KEYSTONE TOWER SYSTEMS INC [US]

Resumen de: US2018195345A1

Devices, systems, and methods are directed to mounting an auxiliary component to a tower based at least in part on a force distribution in which a normal force is greater than a shear force exerted by the auxiliary component on a shell of the tower such that the auxiliary component may be held in place relative to the tower without penetrating the shell of the tower. Thus, as compared to mounting techniques requiring penetration of the shell of the tower, this force distribution along the shell of the tower may facilitate mounting the auxiliary component to the tower with little to no impact on cost and/or structural requirements of the tower. Further, or instead, as compared to other mounting techniques, mounting the auxiliary component based at least in part on this force distribution may reduce or eliminate the need for specialized tools, thus facilitating in-field installation of the auxiliary component.

CONTROL APPARATUS AND METHOD FOR VARIABLE RENEWABLE ENERGY

NºPublicación: US2018195582A1 12/07/2018

Solicitante:
DIFFERENTIAL DYNAMICS CORP [US]

Resumen de: US2018195582A1

Three variable gear assemblies called Transgears, an electro-mechanical rotary frequency converter, and a variable torque and power generator (VT&PG) referred to herein as a variable overlap generator (VOG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow, wind speed, or solar energy. Two sets of three variable spur/helical gear assemblies of sun and planetary gear sets are combined in a mechanical three variable control to form an assembly called a Hummingbird. A Hummingbird control may comprise a constant speed control motor and a constant speed generator to produce required constant frequency and voltage and be reduced in part count and complexity. In order to provide a constant control input, a constant DC voltage can be produced and a DC motor and, for example, a brush-less and commutator-less direct current generator can be used. Once a constant speed is produced, a constant frequency can be produced by a rotary frequency converter. A VOG may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range of renewable energy.
