Title
(EN) SCALABLE AND EFFICIENT MECHANICAL SPEED CONVERTER-CONTROLLED WIND AND HYDROKINETIC TURBINES

Abstract
(EN)
A wind or water flow (hydrokinetic) turbine for harnessing a predetermined minimum or baseload value of renewable electric energy from the wind or water flow energy received at a harnessing module comprises the harnessing module, a controlling module, and a generating module. Han's Principle is that, in a torque balanced three variable Hummingbird speed converter system, from a harnessed input power (input), the generated electric power (output) must exceed the electric power used for the control power (control input) and the input power must exceed the summation of control power and output power. Harnessed input power is provided to a power-balanced three variable mechanical gear control system when a control power of power versus load graph is crossed by an output power line graph to achieve an electrical advantage at a generator output. The three variable mechanical motion control system or "motionics" comprises a Hummingbird control assembly of first and second spur/helical/bevel/miter/ring gear assemblies or Transgear assemblies with an adjustment in between to eliminate variations from constant rotational speed input. The Hummingbird mechanical variable to constant speed control, a control motor and a generator among other components may be mounted on land or a floating platform. Constant electric power at constant frequency are delivered to a variable load.

L'invention concerne une turbine éolienne ou à écoulement d'eau (hydrolienne) permettant d'exploiter une valeur de charge minimale ou de base prédéfinie d'énergie électrique renouvelable à partir de l'énergie d'écoulement du vent ou de l'eau reçue au niveau d'un module d'exploitation comprenant le module d'exploitation, un module de commande et un module de génération. Selon le principe de Han, dans un système de convertisseur de vitesse du type Hummingbird à trois variables équilibré en couple, à partir d'une puissance d'entrée exploitée (entrée), la puissance électrique générée (sortie) doit dépasser la puissance électrique utilisée pour la puissance de commande (entrée de commande) et la puissance d'entrée doit dépasser la somme de la puissance de commande et de la puissance de sortie. Une puissance d'entrée exploitée est fournie à un système de commande d'engrenage mécanique à trois variables équilibré en puissance lorsqu'une puissance de commande du graphe de puissance/charge croise un graphe de ligne de puissance de sortie pour obtenir un avantage électrique au niveau d'une sortie de générateur. Le système de commande de mouvement mécanique à trois variables ou « motionics » comprend un ensemble de commande du type Hummingbird de premier et second ensembles à engrenage cylindrique/hélicoïdal/conique/conique d'équerre/annulaire ou ensembles transgear avec un ajustement entre ceux-ci pour éliminer des variations d'une entrée de vitesse de rotation constante. La commande de vitesse variable à constante mécanique du type Hummingbird, un moteur de commande et un générateur, entre autres composants, peuvent être montés sur terre ou sur une plate-forme flottante. Une puissance électrique constante à fréquence constante est délivrée en sortie à une charge variable.
