Zusammenfassung: | The invention discloses a line forced power transmission judgment method based on multi-source data fusion, relates to the field of power system fault comprehensive processing, and solves the problemthat whether power transmission is tried after a power grid line breaks down or not. If the following ten conditions occur after the line breaks down, forced power transmission is not allowed, namely(1) the line is a whole cable line; (2) the tripping line has no main protection capable of rapidly removing the fault; (3) a report that the tripping line does not have the operation condition is received; (4) high-resistance protection action is carried out on the tripping line; (5) when the line trips, the system is accompanied by an oscillation phenomenon; (6) line maintenance is finished andpower restoration is carried out or a trial operation line trips; (7) the fact that a three-phase short-circuit fault occurs in the line is confirmed; (8) live-line work or live-line spanning construction is carried out on the |
