Abstract

Técnica para a filtragem auto-ajustável de tensão que compensa pelos erros dinâmicos dos transformadores de tensão capacitivos. Um método para que se corrija, de forma digital, a tensão de saída pura (605) de um transformador de tensão capacitiva (CVT), com a intenção de se remover os componentes transientes que impactam na precisão transiente da função de proteção. Um CVT típico é representado pelo uso de três parâmetros no modelo do CVI linear. Um filtro digital (608) é projetado com base nos três parâmetros e incorpora um mecanismo dedicado para garantir a estabilidade numérica do formador. Um motor para o auto-ajuste do referido filtro, tendo como base os eventos do sistema e executado depois que o método tenha sido empregado no campo e alimentado a partir de um CVT especifico.
