One urban power distribution network division methods of the embodiment of the present invention include:
Step S101: according to it is selected it is to be divided wear power grid scope, locality block message and boundary geographic information data；
The boundary geographic information data includes a kind of boundary, the boundary of two classes, three classes boundary geographic information data；
It should be noted that locality block data information may include boundary of land block, land character point in the embodiment of the present invention
Class data, wherein land character can refer to city planning standard, be divided into residential estate, land using for commercial services, public administration with
Service area, industrial land, logistic storage land used, means of transportation land used, public utility land used, greenery patches and land for squares and
Other nine classes of land used, for the land used of mixed nature, taking allows the maximum classification of construction area to use as the plot in the plot
Ground qualitative classification.
For geographic information data of demarcating, one type boundary include administrative area or functional areas boundary, power grid sales department (or
Power supply station) administration boundary；The boundary of two classes includes expressway, through street；Three classes boundary includes that major trunk roads, river, massif etc. are natural
Barrier.
Step S103: acquisition grid equipment data and user data；
In the embodiment of the present invention, it should be noted that grid equipment data include, including having the substation of middle extrusion line
(such as have 10kV or 20kV outlet 35kV and the above substation), medium voltage line, the Unit account of plant such as distribution transformer,
Machine utilization, machine utilization growth rate, device location data, wherein position data refine to plot.User data includes user
Title, user apply to install capacity, apply to install electricity consumption time, location data, and wherein position data refine to plot.
Step S105: dividing three-level grid, include at least, and whether the initialization of three-level grid belongs to according to distribution in grid
Identical medium-voltage line adjust automatically three-level network；
Fig. 2 is one city power distribution grid division methods step S105 of the embodiment of the present invention: it is a kind of preferably to divide three-level network
Embodiment schematic diagram specifically includes:
S1051: the initialization of three-level grid divides three-level grid according to boundary of land block, using plot land character as three-level
All three-level grids are set as not adjusting by grid land character；
S1052: selecting a unadjusted three-level grid, is searched according to the selected unadjusted three-level net boundary
Consistent with its land character and unadjusted adjacent three-level grid judges whether distribution transforming belongs to identical middle pressure in two three-level grids
Route；
If so, step S1053: adjacent three-level grid being incorporated to selected three-level grid, forms new selected three-level grid；
If it is not, then step S1054: nonjoinder；
S1055: judge whether that new selected three-level grid setting has adjusted three-level grid；
If so, step S1056: prompting manual confirmation three-level grid dividing by human-computer interaction interface；
The adjustment at man-machine interactively interface can farthest be kept away as the manpower intervention of adjust automatically and the entrance of verification
Exempt from the error divided automatically and the uncertain factor of adjustment and unexpected factors generate division result, can guarantee of the invention real
Apply the rationalization of the city power distribution grid of example.
If not, continue to jump to S1052, choose it is new do not adjust three-level grid, be adjusted, merge.
S1056: data prediction regulation year is applied to install according to the distribution transformer load in plot, growth rate, land character, user in grid
Each three-level grid load afterwards.
It should be noted that a kind of preferred mode in the embodiment of the present invention, after confirming three-level grid, according in grid
The distribution transformer load of block, growth rate, land character, user apply to install each three-level grid load after data prediction regulation year.
After three-level grid dividing, next the embodiment of the present invention needs to complete the division of level-one grid, specially walks
Rapid S107: dividing level-one grid, include at least, and carries out the initialization of level-one grid, subdivided meshes according to substation's seat number in grid
Interior substation's seat number is greater than the level-one grid of the first preset value, meets according at least to the three-level grid in the level-one grid after subdivision
Level-one grid in prediction result and level-one grid after the main transformer capacity adjustment subdivision of power supply present networks medium-voltage line；
In the embodiment of the present invention, it is illustrated in figure 3 a kind of preferred embodiment schematic diagram of step S107, comprising:
Step S1071: demarcating according to one kind and divide level-one grid, counts substation's seat number in each level-one grid, works as change
When power station seat number is 0, the affiliated substation of medium-voltage line in the level-one grid is counted, which is incorporated to most medium-voltage lines
Corresponding substation level-one grid；
Step S1072: updating level-one net boundary, counts substation's seat number again, and substation's seat number is greater than upper limit value
Level-one grid be set as not segmenting；It should be noted that in the present embodiment in order to optimize level-one net boundary division it is efficient and
Practicability, shown upper limit value are preferably 5, this ensure that power distribution network is only pressing a kind of boundary as far as possible not across one kind boundary power supply
When there is no substation when division, in section, transregional power supply is just considered.
Step S1073: selecting any level-one grid not segmented, according in grid two class boundaries and three classes boundary subdivision
At several level-one grids, makes each newly-generated level-one grid substation seat number within the allowable range, cancel all newly-generated
Level-one grid do not segment setting；
Step S1074: judge whether that all level-one grids have segmented；
If not, step S1075, the selected level-one grid not segmented, execute step S1073；
If so, step S1076: meeting prediction result according to all three-level grids in each level-one grid after subdivision
Predict level-one grid load；
Step S1077: counting the main transformer capacity of voltage supplied route in this grid in each level-one grid, when a main transformer supplies
When the medium-voltage line of the multiple level-one grids of electricity, share each grid main transformer capacity by each grid medium-voltage line accounting；
Step S1078: for each level-one grid, when the ratio of the grid peak load of the main transformer capacity and prediction of statistics
When less than the first limit value, search whether to correspond to ratio there are adjacent mesh greater than the second limit value；It should be noted that for maximum
Degree optimizes the subsequent efficient stable with electric control of reasonability of level-one grid dividing, herein the first limit value and the second limit
Value can be according to those skilled in the art's main transformer capacity according to involved in electricity consumption situation in each urban distribution network and grid situation phase
Voluntarily optimum choice is arranged the peak load situation of pass, the first limitation preferably 1.4 in the present embodiment, and the second limitation is preferably
2.8。
By this step, can more accurately be located for should be able to hypodynamic grid, avoid relying on merely geographical feature and draw
Timesharing is caused since boundary demarcation is improper to the insufficient erroneous judgement of grid power supply capacity, to reduce investment waste.
If so, S10781: manually adjusting level-one net boundary by human-computer interaction interface prompt, make two grid main transformers
Capacity and grid peak load ratio relative equilibrium；
If not, S10782: marking this grid substation deliverability insufficient.
After level-one grid dividing, next the embodiment of the present invention needs to complete the division of level-one grid, specially walks
