afundamento de tensão, afundamento desbalanceado e balanceado, algoritmo de detecçãoAbstract
Afundamento de tensão é um problema recorrente em sistemas elétrico, sendo o mesmo considerado um dos mais relevantes fatores que contribuem para deterioração da qualidade de energia elétrica. Neste artigo, um novo e abrangente algoritmo de detecção de afundamentos de tensão, batizado de ADAMF, é apresentado. O algoritmo pode, rapidamente,detectar afundamentos de tensões simétricos e assimétricos devido a sua habilidade de monitorar, independentemente, a componente fundamental de tensão em cada fase. O valor agregado das tensões, no referencial αβ, é comparado com 0,9 com o intuito de detectar ocorrência deste tipo de contingência. Simulações e resultados experimentais são apresentados para validação do algoritmo proposto.
