Description
Technical field
The present invention relates to power distribution network management method fields, divide automatically more particularly, to a kind of power supply capacity of power distribution network
Analysis method.
Background technique
By major network Power grid structure reason, often there is some region Nei Duozuo substation or 10kV bus need into
The limitation of row load is both needed to its supplied power to sub-load turn by distribution line outside region for the power supply reliability of user
His substation and 10kV bus are powered.When distribution scheduling person's execution turns power supply, need manually to check distribution line item by item
The distribution line communication relationship powered with substation outside region or 10kV bus, and also need to consider whether can make after turning power supply
The problems such as at opposite side substation or main transformer overload.The above traditional approach is difficult quickly to provide when power grid need to promptly be rationed the power supply
Distribution line turns power supply plan in region, causes load control system not in time, brings security risk to grid equipment operation.
Based on the above analysis, it is badly in need of that the condition of load control system can be needed in given region Nei Duozuo substation or 10kV bus
Under, it quickly generates the distribution line that substation or 10kV bus are powered in region and turns power supply plan, be that currently there is an urgent need to solve
