Reducción de la distorsión armónica mediante la operación de un inversor de fuente Z mejorado basado en transformador con alto impulso y control entrelazado

Abstract

This document is aimed at reducing the harmonic distortion existing in a network, which is caused by non-linear loads connected to the distribution system, generating inconvenience and instability in the entire regime that is coupled, for which it is proposed an improved Z-source inverter (ZSI) topology, through the implementation of a photovoltaic SD distributed generation circuit in a 34-bus IEEE test model, in which its behavior is studied when the inverter is connected. improved Z source, establishing study cases when increasing loads on the bar with the greatest impact, in this case bar number 27, for which four forms of study are established, the first being when the system is empty, continuing with the connection of loads to the system, thirdly the implementation and connection of the SD with the SZI inverter in the bus mentioned above, and finally the verification of the system when connecting the SZI and the loads in bus 27 of the network, all this in order to study the behavior of the entire regime when connecting the Z source inverter with interleaved pulse with modulation and the use of inverters connected in series.
