Definitions

  • the present invention relates, as its own title indicates, to a pitch change system or pitch system that is electrically operated by a ball or roller spindle.
  • the step change control system allows optimum extraction over a wide range of wind speeds, also allowing for a high wind safety system. For this they carry complex moving parts associated.
  • the element that connects the blade with the bushing must allow its rotation around its longitudinal axis. Because the angles and the speed of rotation of the blade are reduced, the support systems are usually ball bearings that are subject to heavy loads at times of bending.
  • the rotation system drive consists of an actuator, electric or hydraulic, that transmits the rotation movement to the blade through an additional element such as sprockets, linear actuators, etc.
  • the state of the existing technique for moving a crown is based on the use of a gear of the pinion and rack type (Enercon and G.E.) or of the crank-crank type (Gamesa and Vestas), and there may be other systems such as toothed belts
  • step change systems that are currently mounted on wind turbines with power control by means of the variation of the pitch angle of the blades are based on one of the following actuation mechanisms:
  • spindle type actuators are very physically similar to those used in hydraulic systems. This similarity makes it possible that the interfaces of the spindle (in case of using one per machine) or of the spindles (in case of using one per blade) with the wind turbine can be identical to those used by existing hydraulic actuators; Which implies a total interchangeability between both systems. This would allow wind turbine manufacturers that base their pitch system on hydraulics to make a change to an electric pitch system without having to make major modifications in the design of components such as the bushing or the blade bearing; minimizing the economic impact of the change.
  • Figure 1 is a general view of the bushing and the pitch change systems included in said bushing.
  • Figure 2 represents a sectional view of the interior of the bushing in which the configuration of the linear actuator and its integration with the blade can be seen in greater detail. - TO -
  • Figure 3 shows a diagram of the electrical circuit of the step change system.
  • the pitch change systems are formed by electric actuators (1) and are included in the hub itself (2).
  • An actuator (1) is available for each blade (not shown in the drawing). This provides great precision, superior to that achieved in hydraulic changeover systems.
  • the union of the actuator (1) to the bushing (2) is done through wrists (3) that allow its rotation in a plane perpendicular to the axis of rotation of the blade.
  • the interface with the blade consists of a crank-crank mechanism formed by a fork (4) attached on one side to the spindle (5) by means of a threaded joint (6), and on the other to a bolt (7) solidly connected to in turn with the inner ring (8) of the blade bearing (it is a ring that rotates with the blade), through some blade plates (9).
  • the spindle drive will be carried out by electric motors (11) conveniently sized according to needs.
  • the control of the position of the blades will be carried out by means of linear position sensors placed inside the spindles (5) and controlled at all times by a control system.
  • Various control loops will allow controlling the rotation of the blades (10) in position, speed and acceleration.
  • Said batteries include high capacity capacitors and are capable of feeding not only the electric motors (11), but also the position sensors and the PLC, so that the position of the blades during the emergency can be controlled at all times.
  • the electric motor (11) is used for the movement of at least one of the blades (10).
  • a converter (12) regulates the movement of the motor (11) allowing it to develop sufficient torque and speed for the movement of the blade (10). In the same way the converter (12) controls the frequency, voltage and intensity necessary for the motor (11).
  • the converter (12) is powered either by the batteries (13) or by the network (17).
  • the change of power supply is commanded from a switch operated from the cabinet.
  • the motor (11) is equipped with brakes that allow the blade (10) to be fixed in the desired position.
  • the motor (11) In case of failure of the converter (12) the motor (11) must switch to the emergency circuit (shown in broken lines). In the solution of ce. (15) the motor (11) is connected directly to the battery (13) and in the solution of c.a. (16) the motor (11) is connected directly to the network (17) or to the converter (18) of the generator (19).

Abstract

L'invention concerne un système de changement de pas à commande électrique par un moteur mettant en mouvement une pale. L'actionneur électrique est intégré dans le propre moyeu et couplé par l'intermédiaire de paliers permettant sa rotation. L'interface avec la pale (10) est constituée d'un mécanisme de type bielle-manivelle formé par une fourche (4) unie par une extrémité à la vis (5) par un mécanisme fileté (6) et par l'autre extrémité à un boulon (7) solidement fixé à l'anneau intérieur (8) du roulement de la pale, par l'intermédiaire de plaques (9) de pale. Des capteurs de position à l'intérieur des vis (5) forment des éléments de liaison de contrôle permettant de déterminer la position, la vitesse et l'accélération des pales. Le convertisseur (12) est alimenté par le réseau (17) et par des batteries/condensateurs (13) à haute capacité.
