Proteção Direta de Sobrecorrente no Controle de uma Microgrid Trifásica
Bibliographic record
Abstract
A demanda por energia mais limpa e os avanc¸os nos procedimentos de conexa˜o de unidades de microgerac¸a˜o a` rede de distribuic¸a˜o contribuem para maior participac¸a˜o dessas no sistema ele´trico. Por isto, este artigo propo˜e um novo esquema de limitac¸a˜o de corrente por meio de uma malha auxiliar de controle, que permitira´ limitar a corrente nas unidades sem as desconectar e tambe´m alterar a divisa˜o de carga estabelecida pelos paraˆmetros de controle. Especificamente para o me´todo de controle utilizado, a protec¸a˜o de sobrecorrente limita a corrente fornecida, uma vez que a malha interna de controle de corrente na˜o a faz. A malha de protec¸a˜o proposta na˜o pretende substituir os conhecidos limitadores de corrente de falha. Os resultados de simulac¸a˜o e experimentais de uma microrrede com duas unidades trifa´sicas de microgerac¸a˜o, trabalhando no modo ilhado ou conectado, demonstram a efetividade do me´todo.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
