Asymmetrical Faults Correction Capability in a Power Insertion and Voltage Compensation System

In this work, it is presented an approach capable of improving an integrated power insertion and voltage compensation system via a nine-switch inverter (NSI). This inverter is set to correct asymmetrical faults in one of its operating modes. An instantaneous decomposition into sequence components (IDSC) method is used as a control part during the occurrence of asymmetrical faults in the grid. This is a feature added to this type of system so that it can work under asymmetry conditions. A real-time simulation system is carried out to corroborate the proposal. From the results obtained, it is concluded that the proposed additional functionality is promising, being able to add more robustness to the integrated system via NSI.
