Power system, instantaneous reactive and active power measurement, numerical simulation.


In this paper a new a approach for a three-phase instantaneous active and reactive power measurements is presented. This method principle is based on the line currents and tensions measurements with the Hall leads, transformation them in the orthogonal components employing two AD2S100 vector processors and the instantaneous active and reactive calculus in real time. The validity of these measurements types is confirmed by experiments and numerical simulation results.
