Red container with drive systems



VEM drives system

VEM has supplied drive systems in an insulated container for a research center of the Clausthal University of Technology, where scientists are working on the utilization of geothermal energy.


The bright red container which floated in by crane over the university research center “Drilling Simulator Celle” was not to be overseen. It houses VEM frequency converter technology (690 V, Active Front End, THDI less than 5%) with an output rating of 2 x 600 kW for a highly innovative research project of the Clausthal University of Technology. Together with its partners, the research center is investigating new approaches for the utilization of deep-ground resources.

The aim is to develop a method for the economic future harnessing of geothermal energy from deep sources. The modules combined in the simulator, which are in some cases identical to the actually deployed systems, serve to model the interactions of thermal, hydraulic, mechanical and chemical processes. Planned drillings can also be played through virtually in advance.

The extensive measurements required by such studies must not be influenced by disturbances from the frequency converter. For that reason, VEM has incorporated a EMC filter for the public grid. The frequency converter is furthermore water-cooled. That not only raises the energy efficiency, but also provides for quieter operation.
