Abstract

Patente de Invenção: <B>"MéTODO E APARELHO PARA MODIFICAR O SOFTWARE DE LIMITE E PROTEçãO EM UM EXCITADOR DE GERADOR SìNCRONO PARA COMPENSAR A CAPACIDADE DA TURBINA-GERADOR"<D>. Um método e aparelho para compensar, consistentes com as variações nas condições de refrigeração, funções de proteção e de limite de um gerador. Limites da curva de capacidade do gerador, inclusive a região superexcitada, região subexcitada e região limitada pelo aquecimento da corrente do estator, são modificadas em resposta às mudanças na pressão ou temperatura do líquido refrigerante que depende do tipo de gerador que está sendo compensado. Os sinais de realimentação e pontos de regulagem sendo fornecidos para funções de proteção e limite fixadas, são interceptados e modificados de acordo com a relação entre valores de capacidade nominal do gerador e desempenho do gerador em vista de condições alteradas no líquido refrigerante. As funções de proteção e limite são automaticamente coordenadas. Como resultado, o desempenho global do gerador é melhorado.
