1 Scope
This part of the IEC 61400‑25 series specifies the information models related to condition monitoring for wind
power plants and the information exchange of data values related to these models.
Figure 2 illustrates the information flow of a system using condition monitoring to perform
condition based maintenance. The figure illustrates how data values are refined and
concentrated through the information flow, ending up with the ultimate goal of condition
based maintenance – actions to be performed via issuing work orders to maintenance teams in order to prevent the wind power plant device to stop providing its intended service.
Condition monitoring is mainly based on the following kinds of information.
-
• Time waveform records (samples) of a specific time interval to be exchanged in real-time or by files for analysis (e.g. acceleration, position detection, speed, stress detection).
-
• Status information and measurements (synchronized with the waveform records) representing the turbine operation conditions.
-
• Results of time waveform record analysis of vibration data (scalar values, array values, statistical values, historical (statistical) values, counters and status information).
-
• Results of, for example, oil debris analysis.
It is the purpose of this standard to model condition monitoring information by using
the information modelling approach as described in 6.2.2 of IEC 61400‑25‑1 and by extending the existing information model as specified in Clause 6 of IEC 61400‑25‑2, the information exchange models specified in Clause 9 of IEC 61400‑25‑3 and the mapping to communication profiles as specified in IEC 61400‑25‑4.
