Polluting loads detection in power systems: a decision-making strategy based on nonactive power measurements

In this paper a novel decision-making strategy is proposed for the detection of polluting loads in three-phase power systems. It makes use of simple indices, which are expressed as a function of some nonactive power quantities, previously proposed by the authors and derived from the approach of the IEEE Std. 1459-2000. The decision-making rules for the proposed strategy are presented and discussed, by means of some simulation tests.
