Abstract : this paper introduces the principle of different ial - current protection about motor and the criterion of protection , and the desi gn of hardware and the flow of software are expounded
文摘:介绍了电动机差动保护原理及保护动作判据，阐述了保护装置的硬件设置和软件流程。
( 4 ) based on system identification , the hardware - software system of traction transformer is designed in this paper , in which hardware structure of protection unit and action - criterion of protection are exploringly studied
（ 4 ）初步设计了基于该原理的牵引变压器保护的软硬件系统，着重对保护单元的硬件构成及保护动作判据进行了分析讨论。
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。
