Intelligent system to management of reclosers and proposition of maneuvers in distribution network

In order to face the increasing demand for higher quality, AES Eletropaulo utility company responsible for power distribution in the city of São Paulo, has been using advanced technological resources, such as reclosers on feeders. Currently over 3000 equipment of this nature are installed. To optimize the results provided by these devices, it was developed a switch management system that allows: evaluating their performance by monitoring reports with collective and individual indicators, assessment of the merits of the allocation of devices, supporting maintenance policies, collection, processing and consolidation of measurements allowing better management of the system. It has also developed a module to support manoeuvre, integrated into the SCADA system with the update status information of the switches and loads measured. The adjustments in demand for pre-fault instant makes possible the load off estimation and to propose the optimal sequence of manoeuvres to reduce the fault impacts.
