| 摘 要： | UPFC作为典型的FACTS元件,可以灵活地调节系统的功率传输,但也会造成线路参数变化,影响传统保护的动作,研究含有UPFC的输电线路对传统距离保护产生的影响.针对加入UPFC后造成的阻抗增量,提出两种自适应解决方案,使保护整定值成为可变的阻抗圆,随故障后UPFC状态变化而变化,使得距离保护能正确动作. |
| 关 键 词： | 输电线路 距离保护 统一潮流控制器 自适应 短路故障 |

| Abstract: | UPFC as controllable primary equipment in AC transmission system, can be realized on continuous control of the power system voltage magnitude. Meanwhile, it＇ s also the criterion of action in the amount of power system relay protection device. Point to incremental impedance for adding a result of UPFC, two adaptive programs are presented. The results shows that the programs will enable the protection to response to all kinds of short- circuit fault correctly in the case of having UPFC. |
| Keywords: | transmission line distance protection UPFC adaptive protection short-circuit fault |
