The database of electric mode work order analyzes the distribution line in all distribution line heavy-overload route inventory databases；Judge whether
Cause route heavy-overload due to turning power supply, if it is not, then working out the data value of output for non-turn of caused heavy-overload route of powering
Database；If so, being the caused heavy-overload track data library that turns to power by the data value establishment of output.
4. statistical method according to claim 3, which is characterized in that S5 specifically:
The analysis result of S4 is exported, the distribution line heavy-overload statistical report for considering to turn power supply factor, report content packet are generated
Include: Quan Weidu distribution line heavy-overload Statistical Analysis Report, distribution line heavy-overload statistically analyze specific inventory, reject a turn power supply
Factor distribution line heavy-overload Statistical Analysis Report, turning to power causes heavy-overload distribution line detailed bill and turns to power to cause
Heavy-overload route accounting situation statistics.
