The revolution in the production and distribution of energy is a major challenge for the future. The multiplication of the production points (photovoltaic, wind, offshore) and the "electronic" nature of these new means, as opposed to the traditional means which are based on rotating machines with high inertia, call into question the stability of the networks. to a greater or lesser extent. The study of these phenomena is therefore widespread.
In this context, P + offers source and load emulation means suitable for terrestrial networks worldwide: 110V 230V 270V 400V 690V in a frequency range of 40 to 70 Hz (fundamental). The majority of these sources are linear technology and thus allows accurate and faithful emulation of any type of network. The propagation time between the pilot signal and the output physical parameter is usually a few microseconds, this point is essential to guarantee the stability of the complete system: measurement-computation-emulation
