| 摘 要： | 根据大庆电网的实际情况，对供配电线路整定计算的自适应技术进行研究，提出了供配电线保护的自适应整定算法以及扰动域思想，并在此基础上对传统三段式电流保护进行改造得到自适应三段式电流保护。通过单电源回线算例分析表明，自适应三段式电流保护大大提高了供配线路电流保护的保护范围，从而提高保护的选择性、速动性与灵敏性，使得线路保护的可靠性进一步提高。

| Abstract: | This article studies the adaptive technology in the distribution line protection setting according to actual situation of Daqing electrical network,and proposes the adaptive setting algorithm as well as the thought of disturb region in the distribution line,And transforms the traditional triad electric current protection to the adaptive triad electric current protection.By analyzing single power source distribution line in the Daqing Oil Field partial electrical network,the adaptive triad electric current protection enhances greatly its protection extent,thereby enhances protection selectivity,the speed and the sensitivity and causes the protection reliability further to enhance. |
