Power quality assessment and load identification

The number and power of loads that pollute, from an electric point of view, the electric network are constantly increasing. For this reason, this study aims to define a parameter to assess, in terms of distortion and unbalance, the quality of an electric network. Taking, as a starting point, the advantages and limitations of wavelets methods proposed in the literature, a new index useful for quantifying the load characteristic, is introduced. The efficiency of this index has been verified by computer simulations to assess the method applicability to three-wire measurements of instantaneous power theory, in many realistic situations.
