Impressive. That was the first thing that occurred to TTMS consultant André Handgraaf. An acceptance test of an 800kVA Grid Emulator / Battery emulator. Emulation of an 800kVA AC grid with freely programmable harmonic (up to the 50th) but also voltage dips, imbalance in the three phases and other grid pollution.

The same installation can also be switched to a DC power / DC load with a voltage range up to 1500V and battery emulation.

The customer in this case is a manufacturer of Electrical Vehicle charging stations for fast charging of buses and trucks. With this installation we can test both the mains side and the charging side. In the long run it is the wish to expand the installation to 1600kVA or more.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
