Abstract
In this paper, a multiple harmonic sources localization method based on data analysis has been proposed. Firstly, the relationship between the node harmonic voltage and the branch harmonic current is established according to the circuit theory. Secondly, in power system, there are many power quality monitor data. To reduce the calculation amount, the harmonic active power direction is utilized to the preliminary screening of the harmonic source branches. Then, the mutual information between the suspicious harmonic source branch current and the node harmonic voltage is calculated, if the mutual information exceeds a threshold, the branch is considered to be a main harmonic source branch which results in the harmonic voltage of the concerned point exceed the prescriptive level. The performance and engineering feasibility of the proposed method are verified by the computer simulation and field data.
