("port 2","TE",1,"port 1",1,"transmission",1.334256380792441e-012) Here 1.334256380792441e-012 is the group delay value evaluated at the center frequency of the S-parameter data file (fcfc= 193.1 THz in this case). This value was found using an analytical calculation for the group del...
Specialists found that the calculation they conceived beat the benchmarked models, showing its capacity to tell out PD -impacted examples from sound ones. This study’s after-effects highlighted the eight significant features of savvy learning21. Research22 proposed two systems in light of CNN to ...

As such, the algorithm implements a convergence speed requirement of the global error metric by setting up an environment where each trial model solution competes against each other by achieving the lowest fitting error over a fixed calculation time thus causing a “race” criteria to be ...
However, this method has a drawback in that a fictitious transmission line which causes a time delay equivalent to one calculation time step must be introduced to interconnect the fundamental circuit components. This leads to errors in the calculated response waveforms, degrading the effectiveness of...
A numerical calculation method for transient electrical quantities along a transmission line based on a frequency-dependent parameter transmission line model is studied. Differential protection uses currents from both terminals and can protect transmission lines with excellent selectivity. However, the ...
Besides, the proposed protection has a clear setting principle, low requirements of the calculation amount and sampling rate.doi:10.1016/j.ijepes.2021.107658Junchao ZhengPeng LiKai XuXiangping KongChenqing WangJinjiao LinChi ZhangElsevier BVInternational Journal of Electrical Power & Energy Systems...
