| Abstract: | Through the analysis the action of single-phase reclosing of CSC-103 optic fiber current differential protection device,when in bilateral power souse,pointed out single-phase reclosing defects of fiber-optic pilot device,and puts forward some solutions based on system status quo,further introduces the single-phase adaptive reclosing principle of the coupling voltage criterion.This criterion can drew a quite artificial distinction between permanent fault and transient fault,and is simple and feasible,it can solve defect fundamentally in real application. |
| Keywords: | fiber-optic pilot bilateral power source single-phase reclosing coupling voltage transient fault permanent fault |
