| Summary: | This master’s thesis presents a converter-scale study on Modular Multilevel Converters (MMC). The research has focused on the development of a model based on the analysis of the degrees of freedom available in the converter. Based on the current state of the art, the work addresses a study in Clarke coordinates on possible linear combinations to control the different degrees of freedom and operate on an energy transmission link between a direct current network and a three-phase alternating current network. The validation of the study has been carried out using simulations in Matlab-Simulink, using the available data of the prototype installed in the laboratory. MMCs are widely studied in the literature and the results obtained in this study are similar to those used in real projects, which reinforces their validity. Several scenarios with faults have been simulated in both networks, during which the converter operates with different strategies until the situation is resolved. |
