Wind power

The e.series provides the basis for measuring mechanical loads on wind turbines (IEC 61400-13). The capability of distributed location of the measuring modules, the ability to capture all signals present, including mechanical signals (DMS), meteorological, electrical and position values, and the connection of the modules to the controller using fiber optical cable, satisfy all significant criteria required for wind turbines.

The e.pac DL, high performance test controllers, also allow PC-independent positioning. In this case the controller captures the signals from the modules, calculates statistical data such as the minimum and maximum, standard deviation and mean (vector averaging for wind direction), and saves the dynamic (100 Hz) as well as slow (1Hz) values and the statistical data (10 min) in a USB storage device. If required the controller can also monitor key values such as turbulence and send emails on any events to desired addresses.

Systems with an integrated PC can also be laid out very efficiently with this solution. In this case the controller provides only the unprocessed values on the test.node server solution installed on the PC. Here the statistical data is calculated, the alarm management and other conditioning test.nodes create a data directory on a desired drive in the network, e.g. on a virtual server and save the data in sorted form in the usual formats (e.g. FAMOS). A test.viewer is used for visualization.
