ABSTRACT

A numerical model of the formation of the main indicators of power quality distortion and the generation of multistage and combined distortions is presented. The formation of power quality distortions is carried out in two stages. In the first stage, one of the main parameters of electri­city quality is modeled with a graphical representation and numerical values of its characteristics. In the second stage, the influence of electricity consumers is determined: starting a powerful induction motor, switching compensating devices, and connecting significant single-phase loads on the characteristics of the electricity quality parameter modeled in the first stage. For this purpose, the generated function of the main parameter is modulated by the corresponding function of additional events. The results of such modeling are given in graphical representation and corresponding numerical values. The proposed model can be used in the field of automatic detection and classification of power quality distortions, and verification of the accuracy and reliability of existing algorithms and equipment that perform automatic identification and classification of power quality distortions. All this will contribute to the rapid development of automatic detectors and classifiers of power quality distortions.

KEYWORDS
