摘要
Abstract
For a completely transposed system,a new fault analysis method for six-phase transmission system is pro⁃posed. In this method,the six phases are divided into two groups,and symmetry component method is used directly for the two groups. By decoupling the coupled components of the two groups,six independent sequence components are formed. The composition for each sequence network and six-sequence current angles for different phases based on trans⁃formation are given. The establishment method for complex sequence network with various faults is discussed. Simula⁃tion results show that the new fault analysis method is correct and effective,and it can easily determine whether the in⁃ter-line fault occurs. It is conducive to the realization of fault phase selection and relay protection .关键词
