Itech, supplier of AC/DC Power test solutions has introduced an “all-in-one test solution” with the IT7900P series, a combination of an AC/DC Grid emulator & regenerative AC/DC load. The IT7900 series grid emulator was already innovative considering its many features and user-friendly operation. So with the -P version, the unit is now also deployable as a 4 quadrant load in both AC and DC mode where the unit is also regenerative.

In AC mode, the IT7900P supports various operating modes including CC/CP/CR/CS/CC+CR/CE over a frequency range of 16-500Hz. In CE mode, it is possible to simulate various circuits including single phase DC, RLC and shunt RLC. The Crest factor is adjustable between 1.414 ~ 5.0. Also, this Grid Simulator features an anti-islanding test mode where RLC (resistive-inductive-capacitive), parameters are the define for testing Anti Island sensing circuits.

The Itech IT7900P models are available from 6kVA to 960kVA. The 3 phase output has a voltage range of 0-350V L-N and a frequency range of 16Hz – 2,400Hz in AC source mode. As a DC power supply, the voltage range is -495~495Vdc (1phase/multichannel) and -990~990Vdc in reverse mode. The IT7900P features an intuitive touch screen that ensures smooth operation and includes a built-in power meter, harmonics waveform synthesizer and scope function.

The STEP, LIST and PULSE modes make the ITECH IT7900 series suitable for simulating changing AC and DC grids. This includes e.g. short-lived PQ events. The analysis and simulation up to the 50th harmonic and the programmable output impedance makes the Itech IT7900 suitable for many applications including IEC testing. Remote operation is possible via the standard USB/CAN/LAN and digital I/O interfaces.

"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.”
