troubles inside the sample space
Examples
- Troubles inside the sample space
区内故障 - The technique can distinguish external fault , internal fault and switching on slight fault , without information concerning parameters of the transformer and power system is required
该方法能迅速有效的区分区外故障与区内故障，以及空载合闸于轻微故障的故障电流。 - Even if the fault spread from external fault zone to internal fault zone , the differential protection can avoid misoperation . main criterion of protection is composite - percentage current differential algorithm according to every sampled value , which can accelerate the protection ' s trip , reduce large amounts of calculation and have strong stability to ta saturation
本文采用基于采样值的比率制动式电流差动保护算法作为保护的主判据，可以明显提高保护动作速度和减少计算量；具有较强的抗ta饱和能力，在区内故障时无制动，区外故障时有极强的制动特性。
