In recent decades, the unstoppable introduction of non-linear taxes has contributed to increasing pollution in our electricity networks. And the fact that we were all customers in the past is also long gone, as the increasing integration of alternative, local, energy generation may also make us all suppliers. The degree of pollution is called Power Quality (PQ) and therefore concerns us all. In addition to reliability, the degree of harmonic distortion and grid stability is an important factor.

Network pollution is largely caused by the equipment connected to the network. This can be caused by switched-mode power supplies, PWM control of motors, dimmers, energy-saving lamps, or the switching on of high-power loads. But also power conversion electronics belonging to solar and wind energy installations do not make the situation any better, nor do lightning strikes and short circuits. The influence of all these grid loads is reflected in the form of harmonic distortion, voltage fluctuations and transients.

Drive systems account for almost 70% of the electricity consumption of Dutch industry. To improve efficiency, resulting in significant energy savings, success can almost certainly be achieved in the short term by compensating for the current distortion and instability. Subsequently, the more individual components within the drive systems can be examined for further efficiency gains.

"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.”
