| description | The main purpose of the research is the development and improvement of methods for minimizing power losses for non-sinusoidal and asymmetric modes of operation of power supply systems for suburban houses. To achieve the goal, it has been necessary to make the analysis of existing ways and methods to reduce power losses during non-sinusoidal and asymmetric operation modes. It was proposed to minimize power loss due to the installation of passive and active harmonic filters. The choice of the installation site and the type of the passive harmonic filter was made for the currents of the 3rd and 5th harmonics based on the solution of the two-criteria optimization problem. The calculation of the 3rd and 5th harmonics was completed and after that the value of compensation current was obtained based on the solution of the first part of the optimization problem by the Lagrangian method. The solution of the problem of minimizing the reduced costs by the conjugate gradient method allowed us to choose the type of the passive harmonic filter. Based on the solution of the two-criteria optimization problem, it was proposed to install resonant passive harmonic filters on three supports beginning with the final one, every 100 m. At the same time, the total harmonic current component due to compensation of the 3rd and 5th harmonics decreased to 5.49 %. The installation of four shoulder active harmonic filter on the low-voltage buses of the transformer substation allowed to reduce the total coefficient of harmonic current components to 0.97%. |
