- Title
Simulación de sistemas eléctricos con cargas no lineales y variantes en el tiempo.
- Abstract
This paper deals with a methodology implemented in a computer program with a Graphic User Interface (GUI) that allows us to simulate electrical networks (mainly power converters) with non linear elements. The proposed approach mixes two analysis types in a flexible tool, in that way, we can take advantage of the features of each of them and it permits to analyze linear and non linear systems in the time domain, linear systems in the frequency domain and mixed systems using the proposed hybrid method. The tool is intended to be a versatile and comprehensive computation instrument. Besides, it can be used in a straightforward way to analyze harmonic propagation in electrical networks. Examples from the literature used in electrical circuits, power systems, and power electronics courses are shown. Likewise, in order to analyze non-linear or time-varying loads, test systems were created as a benchmark for testing simulators of harmonics in electrical systems. Simulation results are analyzed and observations about the convergence features and algorithm stability of the proposed method are given. Due to the complexity and computational burden of hybrid analysis, we have selected element models, system models and suitable algorithms to guarantee that the solution is reasonable in terms of simulation time and computer resources.
