Abstract:
Because of unsatisfied relaying protection of short transmission lines, a new differential protection system consisting of microcomputer and optical fiber channel has been presented in this paper. According to this system, a new algorithm including a differential criterion used for the positive sequence currents caused by faults and a difference-half cycle Fourier filtering method has been set up.
