Power hardware in the loop (PHiL) is a variant of the original HiL concept. The concept of HIL is retained and supplemented by additional power -read amplifier- in the loop. In this way, the HIL concept is made suitable for controlling physical components or subsystems that require more power. Think of testing or designing electric motors, transformers or inverters.

In a PHIL system, the equipment to be tested (for example, an inverter) is integrated into a test rig with real-time simulation models of other equipment and systems (for example, a power grid or a wind turbine). The whole is then controlled by a real-time simulation environment that coordinates and controls the behavior of the entire setup. PHIL offers several advantages over conventional test systems, including a higher degree of safety, accuracy, reproducibility and flexibility. It also makes it possible to perform the most sophisticated and complex test scenarios that are difficult to achieve with traditional testing methods.

PHIL is often used in the development and validation of power inverters, wind turbines, solar power systems and other power systems, where system reliability and performance are critical to system safety and efficiency.

"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.”
