| 摘 要： | 六相输电是多相输电技术中最接近实用化的一种.针对其多达120种的故障,运用同正、负、零序和反正、负、零序的六序分量法分析六相系统故障,变换得到的各序分量物理含义清晰.六相系统中的同序量、反序量分别对应于双回线中的反序量、同序量,依据故障边界条件构成的复合序网得到了六相系统的序分量特征以及与六相系统兼容运行的三相系统序分量特征.在此基础上,提出一种判别六相输电系统故障类型的方法,可用作六相输电线路的选相元件动作判据. |

| Abstract: | Among multi-phase power transmission,six-phase transmission is the most feasible one.For the situation of 120 kinds of faults,six-sequence components method,which includes same positive sequence,same negative sequence,same zero sequence,opposite positive sequence,opposite negative sequence and opposite zero sequence,is applied in the fault analysis of six-phase power transmission system,and the transferred sequence components have clearly physical meanings.The same sequences in six-phase transmission power ... |
| Keywords: | six-phase power transmission six-sequence components fault analysis fault phase selection |
