Definitions

  • the present invention relates to a condition monitoring method and a condition monitoring system for wind turbines.
  • Condition monitoring systems so-called Condition Monitoring Systems - CMS, for wind turbines are known in the art. They serve to continuously monitor the states of different components of a wind energy plant, usually rotor blade, drive train, generator, tower, etc., in order to be able to react immediately in the event of a fault or damage and to avoid serious consequences.
  • a CMS typically includes a monitoring device on the component (i.e., typically a computing unit and a number of sensors) that transmits state data and / or evaluated data to an associated database device.
  • a client / server application for example a web server with a browser accessing it, is usually used to visualize the data, the web server in turn accessing the database device and displaying and possibly evaluating the data.
  • condition monitoring method and a condition monitoring system for wind turbines are proposed with the features of the independent patent claims.
  • Advantageous embodiments are the subject of the dependent claims and the following description.
  • the invention is essentially based on the measure of downstream conventional CMS - in particular existing - a central condition monitoring system.
  • This central condition monitoring system includes a central database for receiving status data from monitored components. Since the data supplied by the conventional CMSs, which are also referred to below as component CMSs, are in a manufacturer-dependent form, the condition monitoring system also includes a correspondingly configured data normalization device in order to convert the status data into a uniform format and store it in the database.
  • the data normalization device operates on the basis of a given data standard, to which, in particular, the standard IEC-61400-25 is offered. This standard deals with a common communication base for the control and monitoring of wind turbines.
  • the component CMSs no longer communicate with their own visualization devices (eg web server) as in the prior art, but (at least also) with the data normalization device which receives the data or reads it out from the database of the component CMS, standardizes it and the central database stores.
  • the condition monitoring system comprises processing means for evaluating and displaying the status data.
  • the invention considerably simplifies condition monitoring of wind turbines. It can be a uniform postprocessing and visualization for the status data of all connected component CMSs. The clarity is increased, the operating and monitoring effort is reduced. The training required for the personnel is also reduced since the monitoring of new components or the monitoring of components with unknown component CMS can also take place within the scope of the state monitoring system according to the invention. For this, if necessary, only the data normalization device has to be adapted and expanded.
  • state data which originate from different component CMSs can be compared and / or correlated or correlated with one another.
  • an over-cross analysis of state data relating to the same component but originating from different component CMSs may be performed to verify or increase the validity of results, for example.
  • vibrations originating from the rotor blade can also be measured in the drive train and vice versa.
  • the systems in the prior art operate autonomously, so that the data is not available in particular in time synchronization. Therefore correlated evaluations are possible today.
  • the invention makes it possible to relate the data of different sources to one another in terms of time, which creates a variety of evaluation options. Preferably, based on the score, a representation of the particular condition and / or alarms are generated.
  • the invention provides a uniform visualization and evaluation of state data, which are presented to the management previously segmented in different forms of presentation of the component CMS of different manufacturers.
  • a uniform error message and logging can be achieved particularly easily.
  • the modules for error message and error logging can be based on a uniform system and do not need to be provided multiple times for each vendor.
  • An inventive condition monitoring system for wind turbines is, in particular programmatically, configured to perform a method according to the invention.
  • Suitable data carriers for providing the computer program are, in particular, floppy disks, hard disks, flash memories, EEPROMs, CD-ROMs, DVDs and the like. It is also possible to download a program via computer networks (Internet, intranet, etc.). Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.
  • FIG. 1 shows a schematic of a wind turbine and a preferred embodiment of a condition monitoring system according to the invention.
  • a wind turbine 100 is shown schematically.
  • the wind turbine 100 comprises individual components, such as a rotor with rotor blades 110, a drive train 120, a tower 130, etc., which are controlled by a control device 101 (PLC).
  • the components 110, 120, 130 are each assigned a component CMS 1 1 1, 121 or 131 for monitoring the status of the respective component.
  • the component CMS 1 1 1 for monitoring the condition of a rotor blade may, for example, be a system that detects and evaluates vibrations in the rotor blade.
  • the state data acquired and / or evaluated by the respective component CMS are transmitted by the component CMS 11 1, 121, 131 to a respectively assigned database system 21 1, 221 or 231.
  • the database systems are usually arranged at a distance from the wind energy plant, for example in a control room.
  • the transmission of the data usually takes place in a manufacturer-specific format in which the data are also stored in the respective database system:
  • the transmission is expediently carried out via a WAN (Wide Area Network), for example via DSL.
