Abstract

fetched live from OpenAlex

Neste trabalho propõe-se uma metodologia off-line, prática e eficiente, para detectar, identificar e corrigir erros em parâmetros série e shunt de linhas de transmissão. As linhas de transmissão, ou ramos do modelo barra-ramo, suspeitas de estarem com EPs são identificadas através do Índice de Suspeita (IS). O IS de um ramo é a relação entre o número de medidas incidentes a esse ramo, cujos resíduos normalizados são maiores que um valor pré-estabelecido, e o número total de medidas incidentes a esse ramo. Usando várias amostras de medidas, os parâmetros dos ramos suspeitos são estimados, de forma seqüencial, via um estimador de estado e parâmetros baseado nas equações normais, que aumenta o vetor de variáveis de estado para inclusão dos parâmetros suspeitos. Resultados numéricos de diversas simulações, com os sistemas de 14, 30 e 57 barras do IEEE, têm demonstrado a alta precisão e confiabilidade da metodologia proposta, mesmo na ocorrência de erros múltiplos (em mais de um parâmetro) em ramos adjacentes, como também em linhas de transmissão paralelas com compensação série. Comprovou-se a viabilidade prática da metodologia proposta através da aplicação da mesma, para depuração (detecção, identificação e correção) dos valores dos parâmetros de dois subsistemas da Hydro-Québec Trans-Énergie.

Full frame distilled prediction

Teacher imitation

Not 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.
