Technical field
The present invention relates to a kind of load data processing method, especially relate to a kind of distribution network load conversion method based on circuit cutover.
Background technology
Along with socioeconomic development, power load constantly raises, and power distribution network scale expands rapidly, and distribution turns for mode simultaneously increasingly flexibly, interconnection wiring also more sophisticated.Simultaneously society's raising that power supply reliability is required, also to traffic department when Distribution Network Failure or higher level's electric network fault, the rapidity of load transfer plan is had higher requirement.
Within 2013, Shanghai City company repartitions former functional block and optimizes, and defines new spatial distribution system.Therefore need badly and set up flexible functional block data model, carry out the space load application study based on distribution network planning adjustment, for Electric Power Network Planning provides strong support.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and the distribution network load conversion method based on circuit cutover that a kind of operating efficiency is high, transformation result accuracy is high is provided.
Object of the present invention can be achieved through the following technical solutions:
Based on a distribution network load conversion method for circuit cutover, described power distribution network comprises city function block, burden functional block and mains supply block, and described load transition method comprises the following steps:
1) type of load transition is determined;
2) in city function block, burden functional block or mains supply block is decided to be reference load;
3) obtain the border of each functional block, comprise the border of city function block, the border of burden functional block and the supply district of mains supply block;
4) calculate the circuit proportion of each functional block in its bounds and circuit mounting load, and then obtain load shared by each functional block;
5) by step 1) type determined and each functional block load carry out load transition, and check.
The type of described load transition comprises: city function block is to mains supply block and/or burden functional block load transition; Burden functional block is to mains supply block and/or city function block load transition; Mains supply block is to city function block and/or burden functional block load transition.
Mains supply block is to city function block and/or burden functional block load transition, and the target binding site of mains supply block is locked in community-level.
Shared by described functional block, the computational methods of load are:
