Abstract

In practical situations, the voltage and the current at any supply terminal are not steady-state quantities, since the customers’ load operation and the equivalent impedance of the network vary randomly in time. A search is active for on-line investigation methods able to provide the separation of the responsibility for the electric-power quality degradation. Under nonstationary conditions the methods proposed in the literature require the processing of a great amount of data. In this connection, a statistical approach is recalled in this paper which is aimed to gauge information about the responsibility for the harmonic losses by processing only a limited amount of data. The results of some experimental work show the good performance of the proposed approach.
