As for the lack of literature about the comparison and analysis of harmonic characteristic at the customer side and power side of the same area as well as of comprehensive analysis of harmonic pollution for the supply side

in this paper both the harmonic characteristic and pollution status at the customer side and power side of Dongguan area is compared and analyzed comprehensively. Firstly

a large number of harmonic data for the customer side and power side of Dongguan distribution network is compared and analyzed

the difference in such aspects at the customer side and power side as harmonic characteristic

principle of harmonic responsibility management

harmonic issues at different operation modes and harmonic control proposals are analyzed in detail;Secondly

data analysis of present status of harmonics of the supply side which is concerned too much by the Dongguan power supply enterprises is performed

showing that the present harmonic pollution status at the power side of Dongguan distribution network is more serious. Lastly

the harmonic pollution level for each substation of Dongguan is evaluated and the harmonic pollution distribution diagram in the supply side of Dongguan area is initiatively described. And intuitive help for the analysis of interference source and control strategy of the power side is supplied.
