Definitions

  • the invention relates to a wind power plant having a ground station and a missile connected to the ground station, which has at least one rotor and a generator connected to the rotor. According to a second aspect, the invention relates to a method for operating a wind turbine.
  • a ground station for example via a wire with a missile on which a rotor for generating electrical power is mounted.
  • a wind energy plant of the company Menn which has a helium-filled balloon, on the circumference of which turbine blade-like protuberances are provided.
  • the balloon is lighter than air due to its helium filling and is allowed to rise on a rope. Due to the wind, the balloon starts to spin, which is why a generator connected to the rope and the balloon generates electricity.
  • the electricity is conducted to the ground via a cable connected to the cable.
  • a disadvantage of this wind turbine is that it has a comparatively low speed, so that only a low efficiency is achievable. It is therefore only in rare cases with such a system economically generate electricity.
  • the invention has for its object to overcome disadvantages in the prior art.
  • the invention solves the problem by a generic wind turbine, which has a cooperating with the rotor wind concentrator.
  • An advantage of the invention is that due to the wind concentrator, a comparatively small rotor diameter can be selected, which achieves a high speed. For this reason, advantageously, a comparatively small generator can be used. A small rotor also makes lower demands on the materials to be used, since only a smaller weight must be collected.
  • the wind power plant according to the invention can easily be operated at high altitudes, for example beyond the Prandtl or the Ekman layer. Beyond these layers, the atmosphere has less turbulence, so that mechanical peak loads of wind turbines are avoided. This increases the life of the wind turbine. It is also advantageous that the wind concentrator can be realized with simple means. Movable components are expendable, so that the wind concentrator wears little and is easy to manufacture. The wind concentrator also means that the wind turbine starts up even at low wind speeds, which means that only minimal downtimes occur.
  • a ground station is understood in particular to mean any component of the wind power plant which is designed to fix the missile relative to the earth.
  • the ground station can be, for example, a foundation or a sufficiently heavy dimensioned ground-based mass piece.
  • the ground station may also include a pontoon secured to the sea floor via an anchoring device or a weight. It is possible, but not necessary, for the ground station to be immovable.
  • the bottom station can also be formed, for example, by a ship to which the missile is attached. In this way, the wind turbine can be used to generate power for ships and possibly act as a sail.
  • a missile is understood in particular to mean a component of the wind power plant which can float in the air without supplying external energy.
  • a rotor is understood in particular to mean any device which converts an air flow into a rotary motion.
  • Rotors are, for example, a propeller, a tangential rotor, a cross-flow rotor, a Darrieus rotor, a Savonius rotor or other designs.
  • the rotor may, but not necessarily, be single-stage, that is to say all moving parts rotate in the same direction. It is alternatively also possible that the rotor is constructed in multiple stages. For example, the rotor may be constructed in two stages and comprise two stages of propellers which rotate in opposite directions. In this way, torques can be absorbed in a simple manner.
  • a wind concentrator is understood in particular to mean a device with which wind is concentrated on the rotor.
  • a wind concentrator is designed to increase the wind speed on the rotor.
  • the missile is designed to float in the air.
  • the missile has a support body which is lighter than air and which is designed to act as a wind concentrator.
  • the advantage of this is that the support body performs two functions, namely the one hand to keep the missile without supplying external energy at an altitude above the ground, and on the other hand, to act as a wind concentrator, so that a particularly small and thus lighter rotor can be used can.
  • this dual function allows a particularly simple and elegant construction that is easy to manufacture and transport.
  • the rotor is rotatably mounted about a rotor axis of rotation
  • the support body has a streamlined, preferably a rotational elliptical, a longitudinal axis Trag economistl Kunststoffsachse central body, wherein the support body longitudinal axis of the rotor rotational axis corresponds and wherein the rotor blades extend transversely to the axis of rotation about the central body.
  • the rotor blades protrude perpendicular to the rotor axis of rotation beyond the central body. In this way, air, which flows in the vicinity of the support longitudinal axis to the central body to, passed around the central body around the rotor blades.
  • the central body then acts as a wind concentrator
  • the support body has a rotor shell, which is arranged radially outside the rotor and forms an impeller with the rotor.
  • a disco effect is avoided in which the sunlight is shaded and illuminated in rapid succession on the earth's surface, which is very disturbing for persons staying in the area.
  • the efficiency of the rotor is also increased.
  • rotor blades of the rotor can be brought to a slipstream of the central body by moving on the rotor axis of rotation. In this position, they are no longer directed by the wind, so that no more torque is applied to the generator and it can be easily shut down.
  • the support body has a toroidal outer body, which is arranged radially outside the rotor, so that a rotor blade path of the rotor blades extends between the outer body and the central body.
  • a toroidal outer body is to be understood as meaning a body whose cross-section has a convex closed curve and which extends in an annular manner around the longitudinal axis of the support body.
  • the outer body has an elliptical or teardrop-shaped cross section. In the case of a circular cross-section results an outer body in the form of a torus.
  • the toms is thus a special case of the to- oid outer body in the sense of this description.
  • the toroidal outer body is its simple geometric shape, so that it is very easy to manufacture. Due to its shape, the toroidal outer body is also self-stabilizing. It is therefore possible, but not necessary, for the toroidal outer body to have an inner framework.
  • the outer body may be formed semi-rigid or as an impact body stabilized essentially only by an internal pressure of carrier gas present in the outer body.
  • the support body has two prismatic outer bodies which extend along parallel outer body longitudinal axes and are arranged with their outer body longitudinal axes next to one another so that between them a flow channel is formed, wherein at least two rotatable about respective rotor longitudinal axes Savonius rotors are provided and wherein the rotor longitudinal axes extend parallel to the outer body longitudinal axes and between the outer body longitudinal axes.
  • the Savonius rotors are preferably arranged such that they rotate partly in the flow passage and partly in a slipstream of the outer bodies. In this way, a particularly high efficiency of the Savonius rotor is achieved, since the part of the Savonius rotor, which moves against the wind direction, runs in the lee.
  • the central body and / or the outer body include or include a carrier gas, in particular hydrogen or helium.
  • a carrier gas in particular hydrogen or helium.
  • the advantage of hydrogen in addition to its availability is its particularly low density, so that a particularly large buoyancy is achieved. Due to the altitude of the missile, the hydrogen also poses no significant security risk.
  • Helium benefits from its non-flammability. It is possible that the support body contains both helium and hydrogen, for example in redundant, separate chambers.
  • the missile preferably comprises an electrolysis device for electrolyzing water.
  • carrier gas can be replenished in the form of hydrogen, which inevitably diffuses through an outer shell of the support body to the outside.
  • the missile is connected by means of a flexible connecting element with the ground station, such as a cable made of highly tear-resistant plastic.
  • a flexible connecting element such as a cable made of highly tear-resistant plastic.
  • Suitable examples are high-strength polyethylene fibers such as Dyneema®.
  • an electrical cable is preferably provided which is connected to the connecting element.
  • a water hose is connected to the connecting element.
  • at least one water pump is provided for pumping the water, which is fastened to the connecting element.
  • the water pump is electrically driven, for example.
  • the water pump comprises a fuel cell for converting hydrogen generated in the missile into electricity, wherein the hydrogen is connected via a gas hose, which is also attached to the connecting element.
  • a gas hose is provided to direct either hydrogen as a carrier gas to the missile or to hydrogen in the missile electrolyzed hydrogen to the ground station.

  • the central body and / or the outer body are designed as rigid airships.
  • the central body and / or the outer body may be formed as semi-rigid airships, in particular as Kiel Kunststoffschiffe.
  • the central body and / or the outer body are filled directly with the carrier gas. In this case, they are designed as impact airships.
  • the method according to the invention preferably comprises the step of detecting an altitude of the missile, a comparison of the altitude with a target altitude and the electrolyzing of water, so that hydrogen is produced and pumped as passing the hydrogen into the carrier body.

  • the height control of the missile 14 is done as in the embodiments of Figures 8a and 8b by supplying and discharging ballast from the ballast tank 60th
  • FIG. 9a shows a further possibility for regulating the buoyancy of the missile 14.
  • carrier gas is present, which can be introduced into the carrier gas cell 38 as required. If the buoyancy is too strong, carrier gas can be discharged from the carrier gas cell 38 through an outlet 74.
  • FIG. 9b shows the possibility of the carrier gas cell 38 directly via the gas hose
  • FIG. 10 shows a synopsis of the above, wherein additionally pumps 76, 78, an uninterruptible power supply 82.1, 82.2, a hydrogen storage 84, a water storage 86 and crash warning lights 88 are shown.
  • the missile 14 has in operating position horizontally extending wings. These wings are pivotable about a horizontal axis and are designed to provide additional lift or downforce.
  • the electrical control can be arranged to control the wings so that a predetermined altitude is maintained. This prevents the wind from pushing the missile to the ground.
  • the missile may also include landing skids arranged to support the missile on the ground.
