Abstract

método e sistema para posicionamento de falha e recuperação de conversor de fonte de tensão refere-se a um método e sistema para posicionamento de falha e recuperação de um conversor de fonte de tensão. o método compreende: bloquear uma estação conversora quando for detectado que uma tensão de corrente alternada contém uma tensão de sequência zero ou uma tensão de corrente contínua contém uma tensão desbalanceada; posicionar uma falha continuando-se a detectar a tensão de sequência zero de um lado de corrente alternada do conversor; e recuperar a operação de cada estação após a falha ser posicionada. o método para posicionamento de falha e recuperação é simples e prático, tem alta confiabilidade e pode detectar de forma eficaz os problemas em que cada estação contém uma tensão de sequência zero de um lado de corrente alternada e não pode posicionar facilmente uma falha provocada devido ao fato de que a tensão de sequência zero do lado de corrente alternada é transmitida por um conversor de fonte de tensão para um sistema de corrente alternada do lado oposto; entretanto, por meio do método de recuperação, uma estação não defeituosa de conversor pode se livrar das influências de uma estação defeituosa de conversor para recuperação rápida, recuperação rápida com base em um sistema de estação conversora de fonte de tensão é implantada, e a aplicação de um método de fiação sem transformador no conversor de fonte de tensão pode ser promovido conseguindo finalmente, desse modo, que o espaço ocupado de uma estação conversora seja reduzido, perdas sejam reduzidas e custos de fabricação sejam reduzidos.
