Abstract

detecção de anti-ilhamento para inversor de ligação à rede. uma implementação anti-ilhamento que introduz um padrão de desvio de fase continuamente variável na corrente de saída de um inversor. no modo conectado à rede, esse padrão de desvio de fase não tem impacto sobre a frequência da tensão de saída do inversor. contudo, quando ilhado, o desvio de fase fará a frequência de tensão desviar da nominal. mudanças na fase da corrente de saída, assim, se correlacionam bem com a frequência de tensão, desse modo, um índice de covariância é usado para detectar uma configuração de ilhamento. quando esse índice excede um limite, um padrão de desvio de fase maior é introduzido na corrente de saída, grande o bastante para fazer a frequência de tensão cair fora da janela de proteção de disparo de inversor, sem comprometer a qualidade de potência do inversor ainda assegurando disparo seguro do inversor.
