Preliminary study of the harmonic controlling based on penalty tariff

Viewing the deterioration of power quality,such as the harmonic pollution,the paper analyzed power quality management models such as the emission rights and the harmonic electrovalence.Combining with the status of national electric power system,the paper drew on experience in implementing of power factor adjustment tariff,put forward a new idea of harmonic pollution management based on penalty tariff.At the same time,viewing from the harmonic standards,it put forward the judging basis of the harmonic current exceeded and the calculating method of penalty tariffs.Establishing a network monitoring system and adopting harmonic power meter is the important technical means.The paper concluded the practical significance of implementing the penalty tariff.
