Abstract
The article presents the development of the algorithm for the study of higher harmonics of current and voltage. Research includes the harmonic interaction between transducers and power systems, as well as the simulation of higher harmonics research. The information on the application of the algorithm on the modern tool base is given.
Highlights
One of the main objectives of this work is the development of a method to account for losses caused by higher harmonic currents and voltages
If the condition is not met, the reactive power of the nonlinear load with the existing harmonics is determined and summed with the reactive power losses in the network elements, these values are compared with the value of the reactive power from the source
If the conditions are not met, the reactive power of the nonlinear load with the existing harmonics is redetermined until the required balance conditions are fulfilled
Summary
One of the main objectives of this work is the development of a method to account for losses caused by higher harmonic currents and voltages. There is no doubt that a special need to account for such losses arises when the requirements of GOST 32144-2014 are violated, which set different standards for each harmonic, and depending on the nominal voltage of the network. It is from these positions that it is impossible not to evaluate the existing methods for calculating capacities, their applicability to balance equations, and the calculation of losses caused by the distortions under consideration. It is obvious that these components of losses must be assessed individually, due to their different weight significance, a significant difference in terms of distribution, on the equivalent circuits applied to them and their parameters.
