Using Computer Simulation to Effectively Solve Power Transmission Problems for Non-Sinusoidal Waveforms
Year: 2025
Type: article
Abstract: Nonlinear and periodically switched receivers can cause distortions in current and voltage waveforms within power systems. The growing use of renewable energy sources introduces electrical energy into the system through power converters, which often produce voltages that approximate a sinusoidal waveform rather than being perfectly sinusoidal. This trend poses increasing challenges in designing new systems and managing existing ones. A proper description and interpretation of the physical phenomena associated with non-sinusoidal waveforms have become increasingly important. This paper presents simulation models of power circuits using non-sinusoidal signals and discusses the energy transfer that occurs within them. It also outlines current computational methods based on circuit theories as they apply to these systems. The results from the calculations and simulations in various configurations are compared with data obtained from real objects. The findings highlight fundamental inaccuracies in the methods used and potential errors arising from computer simulations.
