| 摘 要： | 通过严格的理论推导，论证了自适应电流速断保护不仅适用于单回线运行方式，同样适用于双回线或环网运行方式。在双回线上应用时，每回线均装设各自的自适应电流速断保护，自适应电流速断保护在线整定计算式与单回线运行方式下的在线整定计算式相同，大量仿真实验证明，其保护性能明显优于传统电流速断保护。此结论同样适用于环网。 |
| 关 键 词： | 自适应电流速断； 单电源双回线； 双电源双回线； 在线整定计算 |

| Abstract: | Strict theoretical deduction shows that adaptive current fast- tripping protection can be used not only on single- circuit line,but also on double- circuit line.For the double- circuit line,each circuit line has its own adaptive fast- tripping protection and their on- line setting equation is sam e as that of single- circuit line protection. L ots of simulations show that the perform ance of an adaptive protection is obviously better than that of a conventional one.The sam e conclusion can be applied to the ring power net. |
| Keywords: | adaptive current fast- tripping protection double- circuit line with a power source at one end double- circuit line with power source at each end on- line setting |
