Subestações híbridas e convencionais.

Abstract

This report aims to approach in genetal the state of the art of the hybrid substations whem compared with the conventional substations, with respect to the tecnological advances, the design, the maintenance and the operation of the substations. Due to the increasing demand in large urban centers and the overvaluation of areas close to these large load centers, it has become necessary to develop new Technologies to meet growing demand efficiently, occupying a smaller area and being more reliable. In this way, hybrid substations were developed, which are more reliable and occupy areas up to 70% smaller than conventional substation, and can be installed in the middle of large load centers, since they don’t presente a risk of explosion In a generally way, hybrid subtations are excelente real options to meet the growing demand in large load centers, occupy more restrict areas and have a much shorter commissioning and constrution time compared to conventional substations, but without incurring significant costs for the project, operation and maintenance.
