Windtest grevenbroich puts new container for FRT tests into operation

Grevenbroich, Germany - In the middle of April 2019, windtest grevenbroich gmbh (wtg) put another container into operation for testing the grid compatibility of energy generation units.

The container for carrying out fault-ride-through tests (FRT tests) is designed for use in the medium-voltage grid and can measure any type of energy feed device, whether a wind turbine, combustion engine, storage device or photovoltaic inverter.

The provision of system services such as dynamic grid support is becoming increasingly important due to the growing number of power generation units distributed over wide areas. Among other things, generation units must stabilise the grid in the event of sudden voltage changes. This applies to both over-voltage ride through (OVRT) and under-voltage ride through (UVRT) events. By means of FRT tests conducted by independent measurement service providers such as windtest grevenbroich, generation units must prove their grid-stabilising properties according to many national and international standards - in Germany, for example, according to the VDE Application Regulations 4105/4110/4120 and 4130.

In order to be able to satisfy the growing demand not only from manufacturers, but also plant and grid operators for FRT tests, wtg had already taken the final investment decision on the acquisition of a third test container in June 2018. Finally, on April 8, the new mobile container was delivered to the test field for wind turbines in Grevenbroich. This went into operation just two days later.

Over the next few weeks the new FRT container will be measuring a Vensys 120 which was erected at the end of 2015 in the test field in Grevenbroich. wtg has already signed subsequent measurement contracts for further wind turbines and combustion engines.
