- Abstract:
- In the last years the current and voltage distortion in distribution systems has increased, because of the large number of loads, which draw non-sinusoidal currents. The usual measurement methods cannot provide any information about the source of harmonic distortion in a given metering section. Different measurement methods are therefore searched for. The most discussed methods are generally based on the decomposition of voltages and currents into Fourier series. This paper presents a different method for singular or total harmonic sources detection in power systems, based on the instantaneous active power in three-phase circuits. Theoretical aspects are discussed, simulations and experimental results are presented, taking into account measurement accuracy.
