Description

Improvements in Wind Turbines
Field of the invention
This invention relates to the generation of renewable electrical energy using wind turbines, in particular to wind turbines located on existing structures.
Background
The background to this invention is the UK government's expressed desire to foster the development of renewable sources of electrical energy. Furthermore, the UK's Low Carbon Transition Plan has set a target of producing around 30% of the UK's electricity from renewable sources by 2020. Wind power is a major source in the UK for renewable energy. This is usually produced using large wind turbines that can be sited either onshore or offshore. However any onshore wind turbines have met with significant opposition from well organised local groups with the result that planning permission is often refused.
This invention seeks to alleviate the problems that have plagued the installation of many new onshore wind turbine farms, with the result that the UK government's target for the production of renewable electrical energy is unlikely to be achievable.
This invention seeks to avoid this problem by installing unobtrusive wind turbines on top of existing structures.
Summary of Invention
At its most general, the present invention provides a power-generating vertical axis wind turbine mounted on an electricity pylon in order to supply generated power to a nearby substation or end user site.
In a first aspect, the present invention provides a (vertical-axis) wind-powered electricity generation device having: a rotatable shaft; one or more blades fixed to a first end portion of the shaft; a generator connected to a second end portion of the shaft and arranged to convert rotation of the shaft into electricity; and a mounting structure adapted to affix the device to an electricity pylon carrying one or more high voltage cables.
A significant advantage of the present invention is that the installation of such energy generating devices does not create an additional eyesore on an otherwise unsullied landscape. One of the most common objections to new wind turbine installations is that they will be an eyesore, but a modification to an existing electricity pylon (otherwise known as a transmission tower) is likely to meet less resistance.
Moreover, electricity pylons are present in large numbers across much of the world, many of them in windswept areas, so the potential for power generation is very great.
Another important advantage will occur in a number of cases where an electricity pylon is near to a substation or end user such as an industrial site, since there will be no need to install expensive overhead or underground cables.
Preferably, the high voltage electricity cables (power lines or overhead cables) are arranged to transmit electricity at 110 kV or higher voltages. Alternatively, the high voltage cables may be arranged to transmit electricity at 66 kV or above, or 33kV or above.
The one or more blades preferably each comprise an aerofoil shaped such that incident wind causes movement of the blade and subsequent rotation of the shaft.
The device may include two blades arranged opposite one another with the shaft arranged centrally between them. The one or more blades may be elongate and arranged such that they are substantially parallel to the shaft.
The mounting structure is preferably arranged to affix the device such that the rotatable shaft is substantially vertical. Thus, the device acts as a vertical-axis wind turbine, with the associated advantage that it can operate whatever the wind direction. In addition, the shaft can be located centrally within the pylon so as to minimize additional offset loading on the pylon.
The mounting structure is preferably arranged to affix the device to an electricity pylon such that the one or more blades are located substantially above an uppermost part of the electricity pylon, and the generator and/or conversion device is arranged beneath the blades. In this way, the generator and/or conversion device can be stowed within the framework of the pylon.
In embodiments where there the device transmits particularly high loads to the pylon, such as high power output embodiments, it is preferable to locate the generator at a base of the electricity pylon. Thus, the pylon does not have to support the weight of the generator. The device preferably includes an elongate rotatable torque shaft connected between the rotatable shaft and the generator. Similarly, in such embodiments the conversion device is preferably also/alternatively located at a base of the electricity pylon.
The mounting structure preferably comprises: a frame structure arranged to be affixed to the electricity pylon; and a bearing affixed to the frame structure and arranged to support the rotatable shaft. The mounting structure thus facilitates easy installation of the device, and the frame structure may serve to provide additional structural strength or rigidity to the pylon.
The conversion device may comprise: an inverter arranged to convert electricity generated by the generator from direct current to alternating current; a transformer arranged to transform a voltage of electricity generated by the generator to correspond to a voltage of the one or more high voltage cables, or a voltage of a substation, or a voltage of an end user supply; and/or a meter arranged to measure the amount of electricity delivered by the conversion device from the generator to the one or more high voltage cables, substation, or end user supply.
In a second aspect, the present invention provides a power generating assembly comprising: an electricity pylon carrying one or more high voltage cables; and a wind-powered electricity generating device according to the first aspect, the mounting structure of the electricity generating device being affixed to the electricity pylon and the conversion device of the electricity generating device being connected between the generator of the electricity generating device and either: the one or more high voltage cables; an electricity substation; or an end user supply.
In a third aspect, the present invention provides a method of affixing a wind-powered electricity generating device according to the first aspect to an electricity pylon carrying one or more high voltage cables, the method including the steps of: affixing the mounting structure of the electricity generating device to the electricity pylon; and connecting the conversion device between the generator of the electricity generating device and either: the one or more high voltage cables; an electricity substation; or an end user supply.
In preferred embodiments, the method includes the further step of removing an uppermost portion of a framework of the electricity pylon before affixing the mounting structure to the pylon. The uppermost portion may be removed to make room for the mounting structure of the device, the mounting structure providing additional structural strength to the pylon.
Description of Embodiments
The invention will now be described by way of examples, with reference to the accompanying drawings, in which: Fig. 1A shows an electricity pylon carrying a power generating device according to a first embodiment of the present invention; Fig. 18 shows an eiectricity pylon carrying a power generating device according to a second embodiment of the present invention; Figs. 2A and 2B illustrate an example of modifications required to a typical existing electricity pylon in order to accommodate power generating devices according to embodiments of the present invention; and Fig. 3 is a schematic diagram showing the main components of a conversion device for use in power generating devices according to embodiments of the present invention.
The electricity generating device 100 illustrated in Fig 1A is designed to have a power output of approximately 6kW, while the electricity generating device 200 shown in Fig. 1 B is designed to have a power output of approximately 33kW. The device 100, 200 of each embodiment is mounted on an electricity pylon 300, and each comprises a rotor 110, 210, a transition spigot 120, 220, and mechanical equipment 130, 230. The difference between the devices 100, 200 of the two embodiments lies in the size of the rotors 110, 210 and the location of the mechanical equipment 130, 230, as described below. In other respects, the features of the two embodiments are the same, and will be described together below.
In general terms, the rotor 110, 210 is of vertical-axis wind turbine type. The rotor 110, 210 comprises a central rotatable shaft 112, 212 to which two blades 114, 214 are fixed by arms 116, 216. The blades 114, 214 are generally elongate, and are arranged generally parallel with the shaft 112, 212 and directly opposite one another with the shaft 112, 212 arranged centrally therebetween. Wind forces acting on the blades thus cause the shalt 112, 212 to rotate.
A lower portion of the shaft 112, 212 is supported by a bearing 122, 222 mounted on an upper portion of a lattice framework 124, 224 of the transition spigot 120, 220.
The lattice framework 124, 224 is affixed to an uppermost portion of the framework of the electricity pylon 300. The transition spigot 120, 220 enables ease of installation of the wind generating device 100, 200 on existing pylons, and also provides additional stiffening to the pylon structure.
Some adaptation of existing electricity pylons may be necessary in order to locate and fix the transition spigot 120, 220. Fig. 2A shows a typical electricity pylon before adaptation, and Fig. 2B shows the same pylon after adaptation with the uppermost pyramidal lattice framework removed. When installed, the transition spigot 120, 220 provides the structural strength originally provided by the removed part of the pylon.
The mechanical equipment 130, 230 includes a generator (not shown) for converting rotation of the shaft 112, 212 into electricity, and a converter 400 (illustrated in Fig. 3) for transmitting generated electricity either to the high voltage cables (not shown) carried by the electricity pylon 300, or to a local electricity substation or end user supply (not shown). Electricity substations are part of an electricity distribution network such as the National Grid in the UK.
The converter 400 comprises an inverter 410 for converting direct current (DC) generated by the generator into alternating current (AC). A meter 420 receives the converted alternating current in order to measure the amount of generated electricity, and delivers that electricity to a transformer 430. The transformer 430 steps up the voltage of the electricity to either correspond to that of the electricity carried by the high voltage power cables of the pylon 300, or to correspond to that required by an electricity substation to which the generated is to be transmitted. The converter 400 may be housed within a cabinet (not shown), and may further include a transmitting device (not shown) for transmitting measurement data collected by the meter 420 to a remote location.
In the embodiment illustrated in Fig. 1 A the mechanical equipment 130 is located near the top of the pylon 300, within the transition spigot 120 framework. In higher power output embodiments, such as that shown in Fig. 13, the forces applied to the pylon 300 by the rotor 210 may be so significant that it is desirable to locate the heavy mechanical equipment 130 at ground level in order to avoid the loading forces associated with these parts. In such embodiments a torque shaft 500 extends centrally along the height of the pylon 300, so as to connect the shaft 212 at the top of the pylon with the generator (not shown) included in the mechanical equipment 230 located at the base of the pylon. At intervals along the height of the pylon, torque shaft support structures 510 are provided, each support structure having a central bearing 512 to support the torque shaft 500 and ensure its correct alignment.
The invention has been described by way of several embodiments, with modifications and alternatives but, having read and understood this description, further embodiments and modifications wili be apparent to those skiiled in the art. All such embodiments and modifications are intended to fall within the scope of the present invention as defined in the accompanying claims.
