Abstract
Brazilian HVDC transmission systems are relevant to the electricity sector due to their ability to transmit a bulck of energy over large distances. Performing equipment maintenance is the most effective way to increase the reliability of HVDCs that are critical to maintaining systemic stability. Each year, for 80 hours, each of the HVDCs in Brazil can carry out scheduled maintenance with the shutdown of the equipment that is part of the converter transmission function in the preferential period between September and November without payment of a variable portion. HVDC substations are characterized by a high number of equipment in their configuration, because of this, carrying out an optimized planning so that during the shutdown period the greatest possible amount of corrective and preventive maintenance is performed becomes a problem. In this way, the present work proposes the development of an Expert System that through the analysis of historical events and alarms of an HVDC substation, results in a simplified demonstration of the performance of the equipment to assist in the planning of the maintenance shutdown.
