Estudo de caso: sistema de proteção e seletividade de turbo gerador em indústria petroquímica

Abstract

Protection systems of SEP equipment play a key role for network reliability and security. The study of protection and selectivity becomes important as it defines the settings of the devices that act on the system, which preserve the equipment in the event of faults, reduce the area affected and maximize service continuity time. The development of new technologies for identifying, classifying and locating occurrences is in continuous evolution and with technologies widely diversified in the world market. The work addresses the key aspects for synchronous generator protection projects medium and large. In this sense, the different topologies are presented. of protection for electric generators, their damage mechanisms and description of action logic applied to a turbogenerator located in the petrochemical complex of Camaçari-Ba. Finally, performance tests of the main protections are carried out with the use of IED's from Schweitzer Engineering Laboratories to evaluate the performance of the proposed arrangement.
