Item Acesso aberto (Open Access) Avaliação dinâmica da interligação Tucuruí-Manaus-Macapá frente a pequenas e grandes perturbações(Universidade Federal do Pará, 2013-07-11) VIEIRA, Dione José Abreu; BEZERRA, Ubiratan Holanda; http://lattes.cnpq.br/6542769654042813; NUNES, Marcus Vinícius Alves; http://lattes.cnpq.br/9533143193581447This work presents small-signal and transient stability analysis in the Tucuruí- Manaus-Macapá regional system when connected to the Brazilian Interconnected Power System (BIPS). All data used were obtained in the database of the Brazilian National Electric System Operator. Power System Stabilizers (PSS) in Coaraci Nunes and Balbina hydroelectrics power plants, and Maua and Aparecida thermoelectrics power plants are designed utilizing the Nyquist method available in the PacDyn software. The design of the PSS focuses the damping enhancement of the electromechanicals modes, which appears when Tucuruí-Manaus-Macapá´s system is connected to the BIPS. The designs are evaluated on various operational scenarios through simulations in the time domain.
