Regulação dos níveis de tensão em micro aproveitamento hidrelétrico síncrono

Abstract

The use of water for micro and mini hydroelectric generation is a part of Brazilian energy future. This because, near of large load center, the hydrographic basins are already saturated with major enterprises. The mini and micro enterprises are receiving more and more incentive, both financial and regulatory. Along with these incentives, comes the demand of maintain the quality of electric power by the regulators of the electric system. Among the indices that determine the quality of electricity are the appropriate voltage levels. Therefore, this research presents the equation of voltage drop, besides analyzing the parameters that has influence in this fall. Further that, it determines some methods of voltage regulation, to avoid that the voltage level that reach the consumers are not adequate to the demands of Brazilian regulations agencies. Case studies are applied to validate some of the voltage regulation techniques, we can observe the end of the work a comparative table between the voltage and current levels before and after the control methods. In addition to making a comparison of the regulatory effects in the two different case studies.
