Definitions

  • the invention relates to a method for data acquisition from a plurality of wind energy plants, each of which comprises sensors for the acquisition of operating data and a data acquisition unit with a communication interface, data acquisition for participating wind energy plants being controlled by means of a remotely arranged higher-level instance .
  • the invention further relates to a corresponding arrangement and computer program product.
  • Modern wind turbines have a large number of sensors and other units for the acquisition of measurement and operating data, which are used by the operational control of the wind turbine. Much of this data is not only used for the direct operation of the wind power plant itself, but also to higher-level units such as a park master of a wind farm or a control center of the transmission network or to the service provider / manufacturer. The latter type of transmission of business-relevant data is also known as SCADA.
  • a high data quality is required for an evaluation of the data, which generally requires the acquisition and transmission of as much data as possible. This applies all the more to the increasingly important skimming and processing of large amounts of data (big data concept).
  • big data concept In order to meet the great need of such concepts for extensive data of high quality, a large number of different data must be transmitted with high resolution, which means enormous amounts of data. It has been shown that simply scaling up the data transmission used up to now is usually not practical, particularly because of the limitation of transmission bandwidths, computing and storage capacities. It has also been shown that the right data is often missing for rather new questions, since they were not collected or not transmitted, often justified by a lack of transmission capacity.
  • the invention is based on the object of creating an improved method in order to provide extensive, finely resolved data in a targeted manner.
  • a method for data acquisition from a plurality of wind energy installations each of which comprises a generator driven by a wind rotor, an operating control for controlling the operation of the wind energy installation and sensors for acquiring operating data, and a data acquisition unit with a communication interface, and with a remote superordinate one Entity that controls data acquisition for at least a portion of the plurality of wind turbines (participating wind turbines); whereby the superordinate entity for data acquisition is connected to the participating wind energy plants via a communication connection
  • a “higher-level instance” is understood to mean control units or control points that are spatially distant and hierarchically superior. In particular, these can be the operator's control center, network control points of network operators, data centers from service providers or from manufacturers who monitor the operation of the wind turbine.
  • a monitoring user is understood to be a point of use which would like to retrieve operationally relevant data from the wind energy installation and, if necessary, process it. These can also be positions that also act as a "higher-level instance". However, the term is not limited to this: interested surveillance users can also be other positions, for example market participants in the electricity market who market electricity, other observing participants or even research and development groups who are interested in the operating data of the wind turbines.
  • the invention is based on the idea that a dynamically compiled data set enables targeted acquisition of only the data that is really of interest. This targeted recording can avoid the unnecessary recording of other data, which in the specific case is of no interest at all.
  • precisely those data in which there is particular interest can be used with a high temporal resolution, and others in which the temporal resolution is secondary cannot.
  • the invention thus frees itself of the ballast that data that has been recorded but is not required as a result or data that is not required in such a high resolution has traditionally always been displayed.
  • the invention has recognized that the key to such low-ballast or ballast-free acquisition and determination of the data lies in performing the data acquisition on the wind energy plants in a remotely configurable manner. Only those data that are of specific interest are specifically recorded and transmitted to the respective wind energy plants.
  • the configuration data record expediently specifies which data and / or how often the data are to be recorded.
  • Remote configurability thus provides the key to being able to meet the traditionally large data requirements of big data even over narrow-band transmission lines. This is unprecedented in the prior art.
  • the invention makes it possible to respond to the requirements of data acquisition in a more flexible, targeted and individual manner. This increases their efficiency considerably.
  • a type of transmission to the at least one remote monitoring user is preferably defined by means of the configuration data record.
  • the type of transmission can consist, in particular, of determining whether transmission is ongoing or whether it is temporarily stored and then the data is transmitted at a suitable point in time, for example in the presence of free bandwidth. The latter can mean considerable savings in terms of bandwidth requirements.
  • the type of transmission can expediently be set individually in relation to the data requested in each case. It is expediently provided that a dynamic selection of the participating wind turbines takes place by means of the configuration data set. It has been shown that not all participating wind turbines are required for each type of data acquisition. Often a subset is sufficient or the subset is of interest.
  • the data acquisition at the respective wind energy installation is automatically configured accordingly by receiving the configuration data record.
  • the transmitted (new) configuration is only used after a delay.
  • the configuration data record comprises a synchronization element, on the basis of which activation of the configuration data record is controlled.
  • the synchronization element advantageously has a delay condition, in particular waiting for a special command from the higher-level entity, for a predetermined point in time and / or over a predetermined period of time. In particular, this offers the advantage that the time of use of the new configuration is synchronized via the participating wind turbines.
  • a local buffer is preferably provided on the participating wind turbines, which temporarily stores the data recorded in accordance with the configuration data set before transmission, the transmission preferably being carried out continuously or on request, in particular at predetermined intervals.
  • a decoupling of the Data collection can be achieved by data transmission. This is an advantage in many cases, especially when the wind energy installation is only connected via a narrow-band transmission line.
  • a high-resolution recording can be carried out reliably, particularly on wind turbines that are not always connected or only connected via a rather narrow-band transmission line. The certainty that all of the recorded data is thus transmitted can be further increased in this way, which further increases the reliability of the data acquisition as a whole.
  • the data acquisition unit is at least functionally separate from the operational control.
  • the control itself remains unchanged despite changes in the data acquisition or data acquisition unit.
  • the data acquisition unit has its own access to the sensors of the wind energy installation, preferably as a bypass for operating control.
  • This enables completely autonomous access of the data acquisition unit to the sensors.
  • cross-connections to the operational control are completely unnecessary, so that this remains absolutely untouched.
  • the person skilled in the art understands this to mean a hardware abstraction layer. It is an intermediate layer in an operating system or an operational control system, which is generally designed as a logical intermediate layer. It is designed to shield the hardware-specific properties of a target platform from the rest of the actual operational control.
  • the direct access of the data acquisition unit prevents the operational control from being influenced. It is further preferably provided that the data acquisition unit can access the same (ie identical) values as the operational control. This allows replication of the operational control signal environment.
  • the data acquisition unit is advantageously of modular structure, preferably with further selectable expansion modules. It is expediently arranged in or below (ie on the hardware side) the hardware abstraction layer.
  • the modularity enables the functionality of the data acquisition and its scope to be expanded. By doing this in or below the hardware abstraction layer, the expansion can be carried out independently of the respective execution status of the operational control. This increases the flexibility as well as the security against undesired cross influences between the data acquisition unit and the operational control.
  • the configuration data records are preferably formed individually for individual wind energy plants of the participating wind energy plants or individually for a group of the participating wind energy plants. In this way, individual individual circumstances of the respective wind power plant can be specifically addressed.
  • the group is preferably put together dynamically, in particular on the basis of a predetermined parameter.
  • the predetermined parameter can relate in particular to the equipment, variant or the construction status (eg component batches) of the wind energy plants; This is expediently carried out via a link to a master database of the participating wind turbines.
  • the (group) individual formation of the configuration data records enables data to be reduced, since, for example, only every tenth or only one hundredth wind turbine has to be queried, provided this is sufficient for the data to be queried (for example, querying the ambient temperature).
  • a considerably more efficient use of the data acquisition capacity and in particular the capacity of the transmission lines can thus be achieved.
  • the bandwidth of the signal processing of the signal connection to the respective wind turbine is advantageously taken into account when the individual configuration data sets are created. Wind turbines with a high bandwidth capture and transmit more data than those with a rather narrow-band transmission line.
  • the invention further relates to an arrangement comprising a plurality of wind energy plants and a monitoring system for carrying out the method.
  • a monitoring system for carrying out the method.
  • the invention further relates to a corresponding computer program product.
  • a corresponding computer program product For the functioning of the program, reference is also made to the above description.

  • a complex re-certification of the Network models with validation via measurement data can be avoided since the controller 2 remains unaffected with its control program 22 and a corresponding manufacturer's declaration on the unchanged validity of the network model of the wind energy location is still applicable, which simplifies or enables recognition.

Abstract

L'invention concerne un procédé et un arrangement pour l'acquisition de données provenant d'une pluralité d'aérogénérateurs (1, 1', 1") avec une instance de niveau supérieur (53) située à distance qui contrôle une acquisition de données pour au moins une partie des aérogénérateurs (aérogénérateurs participants). Selon l'invention, un jeu de données de configuration est communiqué aux aérogénérateurs participants, le jeu de données de configuration déterminant de manière dynamique les données opérationnelles à acquérir. Une unité d'acquisition de données (4) est respectivement configurée au niveau des aérogénérateurs participants, et les données sont acquises par les aérogénérateurs participants conformément au jeu de données de configuration puis communiquées à au moins un utilisateur de surveillance (54) à distance. Grâce au jeu de données compilé dynamiquement, une acquisition ciblée des seules données réellement intéressantes devient possible tout en évitant une acquisition inutile d'autres données non intéressantes. Cette acquisition ciblée permet d'utiliser avec une résolution temporelle élevée précisément les données qui présentent un intérêt particulier, et non d'autres dont la résolution temporelle est secondaire. Selon l'invention, ceci est réalisé en réalisant l'acquisition de données au niveau des aérogénérateurs de manière configurable à distance.
