摘　　要：对自适应电流速断保护和自适应电压速断保护在单端电源条件下发生正、反方向各种类型短路故障时的保护动作性能进行了分析 ,同时也对它们在两端电源条件下发生故障和系统振荡时的动作行为进行了分析 ,在此基础上提出了进一步实现自适应电流、电压综合速断保护的设想 ,并指出了适用条件和为保证保护正确动作应采取的有效措施。The performance of the adaptive current and voltage instantaneous trip protective relays used on transmission line with single source and two-end sources are analyzed at any point of faults in power network. Also the performances under power swing and voltage circuit broken condition and the corresponding measurement functions should be taken are described. The result shows that the performance of the adaptive current and voltage instantaneous trip protection is satisfactory, and a relay based on proposed principles is quite desirable.
