Resumen
The process of automation in the operation centers involving the equipment of the distribution companies allowed the concentration of a lot of information in the same environment. During a shutdown occurrence, several types of equipment installed in the substations are sensitized generating alarms in the supervision system. These alarms are sent to the operation center to make possible the diagnosis of these occurrences. According to regulating entities, the number of alarms generated in many of these events can be classified as an alarm floods where the operator acts with greater difficulty, thus compromising the quality and safety indicators of the system. In this sense, it is proposed in this study the development of a tool capable of assisting the diagnosis of occurrences in the high-voltage distribution system from information obtained in real situations of disconnections. Two simulations were performed, one for disconnection of a high voltage distribution line and another for the shutdown of a substation transformer where it was possible to observe a significant reduction in the number of alarm messages displayed to the operators in the developed interfaces. The purpose of these interfaces was to provide only the essential information for the diagnosis of occurrences. Evaluating the results of the mentioned simulations it is possible to conclude about the potential of the diagnostic support tool. Is proposed to incorporate it into the existing EMS tools to implement an improvement in the quality of services provided by the companies of the electricity distribution sector.
