The paper presents an efficient mathematical model to anticipate the effects of a transversal impedance installation in a bus of an electrical distribution network harmonic polluted, depending on the harmonic impedance seen in the respective section. There are two aspects of these effects: the amplification of the harmonic conditions in the bus, and the increase of the current on the respective impedance...
In this paper, the validity of the single-point measurements methods and indices, which were proposed for harmonic source detection and sharing harmonic responsibility between utility and consumer, are investigated in a typical distribution system which consists of several critical load cases. A parametrical analysis by means of the variation of the utility side impedance's X/R ratio is also undertaken...
Power quality is an important measure of the performance of electric power system. The main concerns include voltage quality and the current quality. The voltage may contain amplitude errors, harmonics, phase unbalance, sag/dips, swells, flicks, impulses and interrupt/outage. As for the current quality is concerned, harmonics, reactive component, unbalance, excessive neutral/zero-sequence current...
