Disturbing load identification in distribution system network

Abstract

In this paper a new method is proposed to assess the harmonic contributions of a customer in a non radial power system network. This method can determine whether the harmonic pollution at a particular bus in a power system network is due to the supply system or due to the consumer load. This method gives information about the location of harmonic source of pollution in the transmission line upstream or downstream the point of measurement. This strategy is able to detect the prevalent source of harmonic pollution during presence of more than one harmonic source. The dependence of the effectiveness of this method on the sampling frequency has been discussed in details.
