Modelling of the power factor for AC lin

In this paper, a new algorithm to calculate the power factor of linear circuits in non-sinusoidal conditions is presented by introducing the criteria for the relative values of the considered harmonics. The voltage and current harmonics' relative values are utilized to assess the impact of non-sinusoidal conditions on the performance of electroenergetical systems. The methodology involves developing a mathematical model that accommodates the specific characteristics of linear circuits experiencing non-sinusoidal supply voltage. To verify the efficacy of this method, a practical application using MATLAB is provided, illustrating the algorithm's application in real-world scenarios. The study emphasizes the significance of understanding current and voltage harmonics to mitigate undesirable effects in electrical networks while ensuring accurate measurement and pricing for consumers. Findings suggest that the established model successfully correlates the power factor's variation with the relative values of harmonics, thereby enhancing the quality of electrical energy management in non-sinusoidal operating conditions.
