Abstract

"MéTODO PARA A OPERAçAO DE UMA INSTALAçãO DE ENERGIA EóLICA EM SúBITAS ALTERAçõES DE VOLTAGEM NA REDE". A presente invenção refere-se a um método para a operação de uma instalação de energia eólica com um rotor, que transfere um momento de acionamento para um gerador por meio de um trem de acionamento, onde o gerador proporciona um momento gerador préajustável age em oposição ao momento de acionamento e está conectado a uma rede, caracterizado pelo fato de que após uma súbita alteração de voltagem na rede, o momento gerador é controlado dependendo da posição de fase de uma vibração torcional de um trem de acionamento.
