| Abstract: |
| Compared with the traditional converter transformer,the new-type converter transformer has particular connection scheme,for which the remnant conversion method is proposed to calculate its short-circuit faults.Based on the study of the connection scheme and the principle of remnant conversion method,its three-phase mathematical model is established with polymorphic phase coor- dinates.The short-circuit faults of various nodes are calculated with remnant conversion method, which approves its correctness. |
| Key words: converter transformer,short - circuit fault,remnant conversion method,symmetrical component |
