Description

[Technical field]

[0001] The present invention relates to a system for accelerating the rotation of a wind turbine that includes a rotor with a vertical axis of rotation. [Background technology]

[0002] A wind power generation facility including a turbine having a vertical rotation shaft and a generator is known, as described in Patent Document 1. The rotor is provided with a lid that functions as an air tank on its upper cone portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Polish Patent Application Publication No. 422292 Summary of the Invention

[0004] The system of the invention is characterized in that at the upper end of the long shaft, there is a non-reversible transmission connected to a gear motor, which has an electric motor connected by a one-way clutch to a pneumatic motor, which in turn is connected to a magnetic motor. These motors are connected to a mechanism for connecting a generator, as well as to a control unit for controlling the connection of these motors to the shaft, the disconnection of the generator and the operation of the motors. Furthermore, the pneumatic motor is connected to a compressed air tank filled by a compressed air device connected to a turbine generator.

[0005] The system is used when the wind is temporarily too weak to provide sufficient power for the rated rotation speed. The turbine is accelerated using one of the three motors, whereby the pneumatic motors can be connected or disconnected depending on the filling level of the compressed air tank. All engines can work simultaneously or each engine can work individually. When accelerated, the turbines add energy back to the input energy, which constitutes the main advantage of such a solution. The system according to the invention increases the potential of wind turbines, since it allows to store energy.

[0006] Furthermore, by using several different types of engines simultaneously, the system allows for continuous operation of the turbines. [Brief description of the drawings]

[0007] [Figure 1] 1 shows a schematic diagram of a system of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The solution according to the invention is illustrated in an exemplary embodiment with reference to a schematic diagram of the system: The application covers motors of any configuration on a shaft, including a single motor.

[0009] The wind turbine comprises a rotor with a vertical axis of rotation, including two segments 1. The turbine is equipped with a low-speed generator 2 with an inverter.

[0010] On the long shaft of the upper rotor is mounted an irreversible transmission 3 connected to a gear motor 4 which is coupled to an electric motor 5. The gear motor is connected by a one-way clutch 6 to an air motor 7 which is also mounted on the rotor shaft. Above the air motor 7 is arranged a magnetic motor 8. Next to the generator 2 is arranged a control 9 to which the motors 5, 7, 8 and a mechanism 11 are connected. Furthermore, the air motor 7 is It is filled by a compressed air device (not shown) connected to the turbine generator (2). It is connected to a compressed air tank 10.

[0011] The system works as follows: In light wind conditions, the turbine speed is accelerated to about 50 revolutions per minute, so that the generator 2 reaches its rated power. At this time, the rotor shaft of the generator is disconnected using the mechanism 11. After accelerating the turbine, one of the motors 5, 7, 8 that has been driving the turbine is stopped and the mechanism 11 connects the generator 2. The turbine rotates by its torque, becomes a propeller and adds back energy to the input energy, depending on the wind force. If the wind is still not strong enough and the turbine speed drops even with the right force, the connection with the generator 2 is disconnected and the turbine segments are accelerated again to the rated speed.

[0012] The air motor and the magnetic motor may drive the turbine in a continuous operating mode. [Explanation of symbols]
