Title: Method for regulating light intensity output, wind turbine lighting system.
The invention relates to a wind turbine lighting system.
Wind turbine lighting systems are known and are used wind turbines to emit light towards the environment to signal the wind turbine as an obstacle. The wind turbine lighting system usually comprises at least one beacon light which is typically positioned on top of the nacelle. Such lights typically need to comply with local regulations such as for example ICAO, e.g. ICAO Annex 14 Volume 17th Edition, chapter 6, or national regulations, such as FAA regulations, e.g. FAA AC 70/7460 or FAA AC 150/5345-43, or such as the German regulation “Allgemeine Verwaltungsvorschrift zur Kennzeichnung von Luftfahrthindernissen”. Furthermore, the wind turbine lighting system may comprise one or more tower lights, positioned on or in the tower to emit light to the surroundings therefrom. These tower lights are usually low voltage tower lights, and are at present supplied at 24V DC. Such tower lights need to comply with local regulations, such as ICAO, FAA or other as well.
The high voltage turbine lights and the low voltage tower lights are usually supplied with power by a main power supply, typically receiving power from the turbine. The main power supply converts the power to the required high voltage for the high voltage turbine lights and to the required low voltage for the low voltage tower lights. As this main power supply is usually located at the nacelle, a long cable needs to go down towards the tower to the tower lights, resulting in voltage reduction. This requires additional measures in the main power supply to anticipate the voltage reduction over such a distance, such that at least approximately the required voltage nevertheless reaches the individual tower light.
In each tower light, a power supply for supplying power to the light emitting elements is provided. The power supply is arranged for supplying the current to the light emitting element, given the 24V DC supplied power. By supplying a specific current to the light emitting element, a light intensity output that that complies with local regulations is obtained. The power supply is dedicated to supply the appropriate current that is being sent to the light emitting elements, typically one or more LEDs. The power supply is therefore differently arranged for different local requirements, resulting in different types of tower lights to comply with the differing requirement. Since the light intensity output is dependent on local regulations that vary per region and/or country, suppliers and wind turbine installers usually have multiple tower lights in stock for delivery and/or repair. This makes the manufacturing, logistics, maintenance and/or installation costs rather high for both the supplier, the installation partner as well as the wind turbine operator. There is thus a need to simplify the wind turbine lighting system.
It is an object of the invention to provide for an improved wind turbine lighting system that obviates at least one of the above mentioned drawbacks.
Thereto, the invention provides for a method for regulating the light intensity output according to claim 1 and a wind turbine lighting system according to claim 5.
By providing a power supply that is configured for converting the incoming power to a supply power with a determined current level, and by adjusting this determined current level in dependency of the required light intensity output of the light emitting elements, the current level can be used to regulate the light intensity output of the tower light unit. By using the current level to regulate the light intensity distribution, a central adjustment of the current level is possible and the tower light unit may become more simple.
Advantageously, the power supply additionally comprises a controller for controlling the supply power to provide it to the light emitting elements. Such a controller, for a light emitting diode typically comprising a pulse-width-modulator to control the power to the appropriate - in particular - voltage level is usually located near the light emitting element or LED. Contrary to the prior art, advantageously, such controller here is located in the power supply, obviating the need of a separate controller in the tower light unit. As such, the tower light unit can become more simple, and thus, more economical. The required current for the light emitting elements is supplied directly by the power supply including the controller to the light emitting elements. Since the supply power is current driven, meaning that the power supply converted the incoming power to the required current level, irrespective of the voltage level, and the light intensity output of the light emitting elements is related to the current level, by supplying the supply power with the required current level, the required light intensity output is obtained. Any decrease of the voltage level over the distance between the power supply and the light emitting element, is not critical here since the current level is used for driving and regulating the light intensity output. The current level remains approximately constant over the distance from the power supply towards the light emitting elements.
Contrary to the prior art, the current level is now used to regulate the light intensity output. In the prior art, the voltage level is used for adapting to the light intensity output, even such that for a different light intensity output, a different tower light unit of which the incorporated power supply in the factory configured to a different voltage level corresponding with the light intensity output required. According to the invention, the current level can now be set centrally to all the connected tower light units of the wind turbine. So, with a single setting, the light intensity output of the connected tower light units can be adapted. Also, by using the current level to regulate the light intensity output, a light emitting controller that is configured to modulate incoming power to power to be fed to the light emitting element itself, in particular to a light emitting diode, can now be obviated in the tower light unit, as it may be provided in the power supply centrally to the tower light units. Thus, the power with the appropriate current level can directly be supplied to the light emitting elements, resulting in a more efficient, cost effective and reliable system.
Advantageously, the tower light units for mounting to the tower of the wind turbine are arranged in series. It is to be understood that the tower light unit can be mounted to, on, in or through the wind turbine tower wall. The specific mounting of the tower light unit to the wind turbine tower is however not relevant here. By providing the tower light units in series, a single power supply is sufficient to supply the converted supply power to all the connected tower light units. Advantageously, the power supply comprises the light emitting controller as well, and as, such a single power supply with a single controller is sufficient to regulate the light intensity output of the tower light units. Alternatively, each tower light unit may still comprise its own light emitting controller, thus bringing some hardware components into the tower light. However, by bringing the light emitting controller to the power supply, only a single controller is required, instead of a number of controllers equal to the number of tower light units, thus reducing costs. When connecting the tower light units in series, each tower light unit may be provided with a bypass circuit, Such bypass circuit allows bypassing of the light emitting elements in the tower light unit when there is a failure to one of the light emitting elements, or to the tower light unit. As such, even when the tower light units are connected in series, power supply to the other tower light units is not disrupted
By adjusting the current level at the power supply, either directly at the power supply, e.g. via an interface, or remotely, the current level is used to regulate the light intensity output. The current level can be set during commissioning or testing of the wind turbine, or when the local regulations change. Normally, the current level is set once and then remains the same until a change in local regulation requires adaptation to a different hght intensity output.
The current level can be set continuously, or discrete. With a continuous setting of the current level in the power supply, there is a direct relation between the required light intensity output and the current level. For example, a knob, either mechanically on the power supply or virtually, of which the position can be changed in dependency on the required light intensity output. The scale on the knob might even be mentioned in hght intensity output. Alternatively, the current level of the power supply may be set to discrete values. So, when the required light intensity output is between certain values, a predetermined setting can be chosen, etc.
Preferably, the power supply associated to the tower light units is provided in proximity to the tower light units, preferably within a range of about 50 meters or closer in an inside of the wind turbine tower. Then, the power supply can be accessible for maintenance, repair and/or adjustment of its setting. More alternatively, a number of power supplies can be provided in the wind turbine tower, each power supply associated with a single tower hght unit, wherein each power supply is configured to convert incoming power to a predetermined current level that is set in dependency to a required light intensity output. Here, each power supply requires an individual setting of the current level, however, a central interface might be configured that then directs the set current level to each of the power supplies to minimize errors and misaligned settings. In this embodiment as well, the controller for the light emitting elements, can be comprised in the power supply or can be comprised in the housing of the tower light unit.
By using the current level of the supply power to regulate the light intensity of the tower light unit, a simple and cost effective wind turbine lighting system is obtained. The tower light units itself can become more simple, and thus more cost effective, also maintenance, repair etc. can become more easy. Additionally, both for the manufacturer as for the wind turbine operator, it now suffices to have a single type of tower light unit in stock, instead of, as in the prior art, various types each corresponding to the differing local regulations. Also, a single power supply for all the tower light units can be sufficient, which provides for a cost effective, simple, reliable and robust system.
Further advantageous embodiments are represented in the subclaims. The invention further relates to a wind turbine.
The invention is further elucidated by means of a drawing. In the drawing shows:
Figure 1 a schematic view of a wind turbine with a wind turbine lighting system;
Figure 2 schematic diagram of an embodiment of the wind turbine system according to the invention.
In the drawing, the figures are given merely as a schematic representation of the invention. Corresponding elements are designated with corresponding reference signs.
Figure 1 schematically shows a wind turbine 1 comprising a wind turbine tower 2 on which a nacelle 3 and wind turbine blades 4 are mounted. The wind turbine 1 can be erected offshore or onshore. Typically, the wind turbine 1 is provided with a wind turbine lighting system 100 for marking the obstacle with respect to upcoming air, land or naval vehicles. Such a lighting system may comprise obstacle lights that can be mounted on the nacelle 3, not shown here. The wind turbine lighting system 100 may further comprise at least one tower light unit 101. The tower light unit 101 typically comprises at least one light emitting element, such as a light emitting diode that is arranged to emit light to the environment of the wind turbine tower in a predefined light pattern. Local or regional rules and/or regulations may prescribe the required light intensity output of the light emitting elements of the tower light unit.
There is provided for a power supply 300 that is arranged centrally to the tower light units 101, meaning that the tower light units 101 are being connected to the power supply 300. Advantageously, the power supply 300 is also positioned relatively centrally with respect to the tower light units 101 inside of the wind turbine tower 2. Preferably, the power supply 300 is positioned relatively close to the positions of the tower light units 101, such that it can be relatively easy accessible inside of the tower 2. The position of the power supply 300 however is more determined by practical reasons, such as space inside of the tower, accessibility, etc.
According to the invention, the power supply 300 receives power from a main power supply, that may for example be positioned in the nacelle and may for example receive power directly from e.g. the turbine of the wind turbine 1.
The power supply 300 is configured to convert the incoming power to power with a predefined voltage and/or current level. According to the invention, the power supply 300 is configured to convert the incoming power to power with a predetermined current level. This current level corresponds to a required light intensity output, and, as such, the current level is used to regulate the light intensity output. This is opposite to the prior art wind turbine tower light systems, as they are all voltage-based.
Advantageously, the current level to which the power supply 300 is to convert the power, is adjustable. So, during commissioning or testing, the current level, and thus, the light intensity output can be set to comply with local and/or regional rules and regulations.
In the embodiment shown in figure 1 and the schematic diagram of figure 2 also provides for a light emitting controller 200 comprised in the power supply 300. Such light emitting controller 200 is, in particular when the light emitting elements LI - Ln are light emitting diodes, usually provided to further regulate the power to a voltage level that is acceptable for a light emitting diode, as these diodes usually operate at voltage levels between about 1 and 5 VDC. Since, here the current level is provided by the power supply 300, the controller 200 mainly needs to adapt the voltage level to the voltage level for the LEDs. According to the invention, the light emitting controller 200 is comprises in the power supply 300, preferably in the same housing as the power supply 300. As such, a single, robust component can be provided via which the current level is adjustable. By providing the controller 200 in the power supply 300, a single controller 200 can be sufficient for all the connected tower light units 101. So, an individual controller in each tower light unit 101 can be obviated, further providing for a simple, reliable and robust tower light unit 101.
When providing a single power supply 300 with a single controller 200, it is advantageous to connect the tower light units 101 in series to the power supply 300, as indicated in figure 2. Each tower light unit 101 comprises light emitting elements LI to Ln. In the tower light unit 101, a bypass 102 is provided, such that, in case of failure of one of the light emitting elements LI to Ln or in case of failure elsewhere in the tower light unit 101, the power still can be supplied further to the other tower light units 101 in the series.
In an alternative embodiment, not shown here, an adjustable power supply 300 and controller 200 can be provided for each tower light unit, inside of the tower, such that the tower light unit 101 can be simple and robust. Also, the tower light units 101 do not need to be connected in series, but are each individually connected to their own power supply 300 and controller 200. To minimize mistakes and/or errors, a single interface can be provided that allows for the setting of the current level and transmits this setting to each individual power supply. Although the tower light units 101 do not need to be connected in series, providing multiple power supplies may be less efficient and relatively costly.
The power supply 300 can be provided with an interface or with a remote access module via which the current level can be set, preferably during commissioning or testing of the wind turbine. Such user interface may be accessible directly or remotely. For example, a user may have the choice to select either one of a lOcd, 20cd, or 30cd light intensity output, or another value. Please note that the numbers are fictive and are mentioned for illustration purposes only. The user interface, such as a hardware knob, may be equipped with a controller that translates the selected light intensity output to the current level for the power supply 300. To that end, such a controller may be configured with a table giving the relation between light intensity output and voltage level, which relation may be linear or nonlinear, or may be configured with a calculation module for calculating the corresponding voltage level. Typically, the setting is a single-time setting that lasts for the lifetime of the wind turbine since the setting is dependent or corresponding to the local regulations. However, should, during the lifetime of the wind turbine the rules or regulations to which the light output of the tower light units, the current level to which the power supply is to convert the incoming power can be easily adjusted, such that, without any replacement of power supplies or tower light units, the turbine lighting system, in particular the tower light units, emit a light output according to the new regulations.
