The wind turbine is already running optimally. 2) The wind turbine is worse than the fastest in the wind farm. If this is the case, then the normal adjustment program is started. Here, the wind turbine receives the current operating data of the currently fastest wind turbine reported. The wind turbine's internal self-tuning program now starts self-calibration using the best wind turbine data and sweeps 15 degrees plus and 15 degrees minus the best wind turbine's operating values and stores its own operating values and wind speed degrees during auto-calibration. Once the calibration procedure has been carried out, the wind turbine is adjusted to the wind direction at which it has run best during calibration.

  • the Scout adjustment allows a faster start of the wind turbines after a wind drought. Because when a single wind turbine starts again in any neighboring wind farm, this information is immediately available to all wind turbines of neighboring wind farms and the wind turbines receive the information that is necessary to align themselves as quickly as possible with the wind.
  • the present invention supplements the individual wind power wheels with two self-adjustment programs, wherein the SCOUT adjustment program is adapted dynamically to the respective wind conditions (FIG. 3 - upper half). These self-tuning programs are activated whenever the wind power plant passes its operating data to a common data server and it receives the message back that another wind turbine is running better.

  • the individual wind turbine can find the best wind setting itself All wind turbines for data exchange work together and exchange the current operating data via the common server, which enables the wind situation to be tested by the system (consisting of all wind turbines)
  • Each wind farm is a stand-alone weather station, delivering its data to a central wind farm
  • the wind power wheels are not centrally controlled, but they control themselves.
  • Each wind power plant remains in a system according to the invention an independent INDIVIDUAL and is only in contact with his conspecifics to achieve the best performance together.
  • the present wind power control does not replace the existing autarkic control systems of the individual wind turbine, but supplements it with an additional information system.
  • the respective wind turbines report the current operating values to a common server and in this case receive the message as to which wind turbine currently runs the fastest with which settings and most of the electricity supplies.
  • These operating values are very important information for the individual wind turbine and the wind turbine is now able to find the best setting for itself with this data value information and a self-tuning program.

  • the data information happens in dynamic time intervals. An adaptation to the best wind situation is possible. Also, the system allows different wind conditions in an area to be taken into account, since not only the harmless data of the best wind power station are accepted and set harmlessly at the start of the self-adjustment program, but the self-adjustment program has a bandwidth of 15 degrees plus and 15 degrees minus the values of the best running wind turbine. During the adjustment phase, the operating values are sent to the server and the wind turbine then moves, after the adjustment process, with the data values which enable the highest energy yield.
  • each of the worst wind turbine is appointed scout. It launches the scout program and seeks its best setting in even greater bandwidth.

  • Malfunction database and e-mail notification It can also be determined from the current data values whether a malfunction has occurred in a wind turbine.
  • the respective error code is communicated to the central server. If an error code appears, this message will be sent to the e-mail address, which was communicated during the installation of the wind turbine. In the email, the error code is communicated and there is a hyperlink that allows the email recipient to log into the wind turbine and retrieve all data values.
  • Data synchronization between the wind turbine and the central server It has already been described above that each wind turbine reports the current operating data to the central server at dynamic time intervals. The data sent is stored in the operating database. If the wind turbine is integrated in a wind farm, the data server determines whether there is a wind turbine inside the wind farm that turns faster and produces more power. If this is the case, then the wind turbine will be reported back this data.
  • Self-optimization of the wind turbine by the data of the central server If a wind turbine has received the message that another wind turbine is running faster, it can now align itself with the same number of degrees and the same angle of the rotor blades and thus increase its own performance. Here, the wind turbine is adjusted so that it is overdriven by a few degrees until it is set with the notified value. In the event that the wind turbine reaches even better values during the self-adjustment than the data values of the central server indicate for the best wind turbine, the wind turbine remains in the better found position and sends this data back to the central server.
  • the other wind turbines now also receive the data of the best wind turbine and can use these data values for self-optimization.
  • Optimization of the wind farm by the data of the best wind turbine The wind turbines of a wind farm are fed via the central server with the data of the best wind turbine and can achieve a better wind yield during the self-optimization.
  • Our data server supplies all wind turbines with the latest data required for optimum power generation.
  • the Scout System for Wind Farms In wind farm installations, ie when combining several wind turbines into one wind power park, there is always a wind turbine that currently has the worst data values, rotates the slowest and produces the lowest power output. This wind turbine will now be scouted for its current data request. His job is now to activate the scout program. This program oscillates with a larger difference range around the values of the best wind turbine, whereby the wind turbine remembers the best operating values. Once the scout program has been run, it goes back to the values that gave the best operating values. Then the current operating values are reported back to the server. The scout system therefore allows even greater fine tuning.
  • Geo-coordination of the wind farms also makes it possible for the data from neighboring wind farms to be compared. If it is the case that an adjacent wind farm has wind turbines with better operating values, then the neighboring wind farms will be given the data of the best wind farm. This best value can then be communicated to the scout wind turbine.
  • the Scout wind turbine uses these settings in the Scout program and can then test whether the data values of the neighboring wind farm can also improve performance in its own wind farm. This system allows the data values of neighboring wind farms to be mutually used to obtain even better energy yield.

Abstract

L'invention concerne un procédé servant à exploiter, en particulier à calibrer des éoliennes. L'invention concerne en outre un parc éolien comptant une pluralité d'éoliennes qui sont contactées ensemble. Ainsi, l'invention expose un procédé servant à exploiter des éoliennes (1, 1', 1"). Les éoliennes (1, 1', 1") sont reliées à une unité centrale de communication (3) et envoient à l'unité centrale de communication (3) des informations et/ou des données concernant leur puissance réelle respective ainsi que concernant leur réglage réel correspondant à leur puissance réelle respective. L'unité centrale de communication (3) compare les puissances réelles reçues les unes aux autres et envoie et/ou transmet sélectivement des informations et/ou des données concernant un ou plusieurs réglages réels correspondant aux puissances réelles respectives à une ou plusieurs éoliennes (1, 1', 1"). Les éoliennes (1, 1', 1") disposent chacune d'une unité de commande (5, 5', 5") qui, compte tenu des informations envoyées, provoque au moins un premier nouveau réglage de l'éolienne concernée (1, 1', 1") et au moins un deuxième nouveau réglage de l'éolienne concernée. Après la commande des deux nouveaux réglages ou plus, l'éolienne (1, 1', 1") conserve le nouveau réglage présentant la plus grande puissance réelle ou l'éolienne (1, 1', 1") est amenée dans le nouveau réglage présentant la plus grande puissance réelle.
