Project start VirTuOS
As part of the VirTuOS project, a new test procedure for inverter component tests based on power hardware-in-the-loop (PHiL) test benches will be developed and investigated with regard to the suitability of development and certification tests.
The certification of the electrical characteristics of a wind turbine (WT) in the field is a very time-consuming and cost-intensive procedure. The grid operators specify that the correct wind conditions with a stable grid must be available at the time of the test and that the necessary staff and test equipment must be available on site.
It follows that development and certification testing should be performed at the component level with the benefit of cost and resource savings. The establishment of novel component-level testing processes for the development and certification process requires that the experiments carried out allow reliable conclusions to be drawn about the properties of the WTs tested.
In the VirTuOS research project, a novel test procedure for inverter component tests based on power hardware-in-the-loop (PHiL) test benches will therefore be developed and validated with regard to its suitability for determining the electrical properties in accordance with FWG TR3, whereby the novel procedure is characterized by Internet-based networking. This offers the possibility to couple the real test bench components and the main inverter as a device under test with virtual system components, e.g. a wind turbine simulator for the simulation of the missing system behavior, and thus to build up a geographically distributed virtual overall system beyond the actual test bench boundary.Copyright: © BMWK
