Diseño e implementación de un transformador zig-zag para mitigación de armónicos de corriente.

Abstract

It is known that there are a number of non-linear loads connected to our SEP, the same ones that cause distortion of the sinusoidal wave, causing harmonics to appear in the grid, the same ones that are a pollution to the electrical grid, which causes the sinusoidal wave damage.

Harmonics are voltage or current signals that have a whole frequency multiple of the fundamental frequency of the electrical network, which are added to the main voltage or current wave, distorting it. It is known that currents do not generate useful work, so the presence of these results in loss of power and energy. They have consistently been a major problem in the field of electricity, causing serious inconveniences in the electricity grid. Within the harmonics, we have the third harmonicas, which in this degree work will be the main objective of study and mitigation.

In this titling work, the third harmonics produced by LED lamps in combination with a SIEMENS SINAMICS V20 speed variator that powers a three-phase motor and the ZIGZAG transformer method for the correct mitigation of these will be highlighted.
