Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/17232Fixed capacitor banks are equipment commonly used in industrial plants to correct power factor and/or mitigate undervoltage in their distribution networks. At heavy load levels, capacitor banks play an important role for reactive power compensation in industrial plants. On the other hand, during light load levels, the reactive power injection from capacitor banks can cause overvoltage in distribution circuits of industrial plants. The voltage variation problem in an industrial plant can adversely affect the useful life of its equipment. The combined use of fixed and switched capacitor banks is an alternative solution for mitigating steady-state voltage variation problems in industrial plants. This master dissertation proposes and investigates a technique to mitigate steady-state voltage variations in low voltage distribution circuits of a beer plant, located in the city of Benevides, PA. The proposed method is based on the reactive power compensation supplied fixed and switched capacitor banks. In recent years, the voltage quality problem has been observed in the above-mentioned beer plant, causing a drastic reduction in the useful life of its equipment. A set of real measurement data from the beer plant site was used in time-series load flow simulations, using OpenDSS software, to evaluate the proposed mitigation technique.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Sistemas industriaisIndústria cervejeiraQualidade da tensãoBanco de capacitores chaveados.Industrial plantBeer plantVoltage qualitySwitched capacitor banksDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICASISTEMAS ELÉTRICOS DE POTÊNCIASISTEMAS DE ENERGIA ELÉTRICA
