Apresentação e aplicação do software ANAFAS em estudo de curto-circuito

Abstract

The National Interconnected System (SIN) undergoes modifications at all times, with input and output from network elements. These changes occur because of changes and expansions in the generation and transmission systems, as well as system load changes. In order to minimize the impacts caused by these modifications and accesses, and to guarantee the correct connection by the accessors, the National Electric System Operator (ONS) proposes network access rules consolidated in Network Procedures. In order to meet the criteria established in the Network Procedures and to facilitate access studies, the Electrical Energy Research Center (CEPEL) developed the ANAFAS (Simultaneous Fault Analysis), which is a network short circuit analysis software electrical, capable of simulating simultaneous faults, orient results to the point of fault or to the point of monitoring, perform network equivalents, study of breaker overcoming, among others. Integrated with ANAFAS, SAPRE (System of Analysis and Design of Electrical Networks) that offers an interface of editing diagrams, facilitating the analysis of electrical phenomena. This work aims to present the functionalities of these softwares, in an explanatory and exemplified way through case studies.
