In recent years, the debasement of power quality of a distribution system such as the increase of power system harmonics has been apprehended. It is thought to be causally related to the diversification of loads by progress of power electronics technology and the increase of the number of interconnection of distributed generators for home use with the reduction of the effect on the environment. The harmonics cause not only deterioration of power quality but also further various problems. In this paper, the authors propose an estimation method of harmonic sources by separating the harmonic current flowing through the distribution lines. In addition, the authors carry out the numerical calculation and experiment in order to verify the validity of the proposed method. IndexTerms--Distribution system, harmonic sources, interconnected inverter, power quality, power system harmonics I.

Recently, non-linear loads have diversified and increased. It results in deterioration of power quality on a distribution system, since the equipment, which includes the non-linear loads, generates harmonics. The harmonics cause not only deterioration of power quality but also further various problems. Nowadays, the state of harmonics is becoming evident by the recent researches. However, since the harmonic analysis by using a detailed model of distribution system is too difficult, the analysis is carried out by a simplified model. In this paper, the authors construct an analytical distribution system model in consideration of the non-linear loads with the harmonic sources based on the practical data. Moreover, the influence analyses of harmonics are carried out by using this model. In addition, the authors estimate the harmonic sources in the simplified distribution system.
