Home » Chroma 61800 Series three-phase AC power supplies
The Chroma 61800 series three-phase AC power supplies are regenerative grid emulators. The series consists of seven models with 9 kVA, 12kVA, 15 kVA, 30kVA, 45kVA, 60kVA and 105kVA power respectively. This can be extended by a master / slave linking of 5 units up to a maximum of 300kVA. The 61800 units are complete 4-quadrant AC power supplies. They are not just an AC power supply but also a regenerative AC load. The regenerative concept makes the 61800 series ideal for testing solar panel inverters, simulating a micro grid and applications with electric vehicles.
The output voltage (L-N) can be set between 0-300Vrms (optional 0-400Vrms L-N) per phase, the frequency being adjustable over a range from 30Hz to 100Hz. Both frequency and voltage can be increased and lowered slowly with a programmable slew rate. Incidentally, these power supplies can also be used as a single-stage AC source. With a Crest Factor (CF) of three, the unit is also suitable for high peak currents.
The growing use of PV/solar inverters, wind energy systems, etc. increases the need for clean and reliable energy sources. Test standards have been developed for this purpose, such as IEEE 1547, IEC 61000-3-15 and IEC 62116, which are related to this type of grid emulators and for which this series can be used. The 61800 is also suitable for use in smart GRID and EV related test applications, such as in Vehicle to GRID (V2G) and Energy Storage System (ESS). As an AC power supply, the 61800 series can be used for test applications such as IEC 61000-3-2-2/-3-3/-3-1/-3-1/-3-12.
All these tests are easy to execute thanks to the extensive software supplied free of charge.
An RS-232, GPIB, USB and Ethernet interface are standard included. Additionally, there is also an analog interface available that transforms this power supply into an amplifier. In combination with an arbitrary waveform generator you can produce any desired waveform.
Extensive measurement functions also ensure good documentation of the actual values of current, voltage and power. Control and readout of the measured values are carried out via the large LCD display.

"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.”
