摘要
在阐述传统电流速断保护和自适应电流速断保护构成原理及特点的基础上,对自适应式电流速断保护在单端电源条件下发生在正、反方向故障时的动作性能进行了分析。结果表明,自适应电流速断保护性能比传统电流保护具有明显的优越性及适用条件。
The traditional current instantaneous trip protection is easily effected by the running conditions and fault types,while the adaptive current instantaneous trip protection can overcome these defects.This paper mainly describes the principles of traditional current protection and adaptive current instantaneous trip protection,and analyses the operation characteristics of adaptive current instantaneous trip protection that on the positive or negative direction of transmission lines with single source when any point of faults occurred in power distribution network.A conclusion can be given that the adaptive current instantaneous trip protection surpasses the traditional type in the protection performance.
