Layout, solve the problems, such as county domain grid contact weakness, isolated power grid, meet basic electricity demand.
One：Urban distribution network planning model study
(1) distribution gridding planning and designing model (" 131 model ")
With county (area) as unit, based on urban land_use plan (" 1 "), power distribution network is divided into " distribution, function, electricity consumption " three
Layer grid (" 3 "), on the basis of stress and strain model, planning forms power supply unit (" 1 ")：
【Explanation】
Distribution grid：In grid structure, distribution grid is the relatively independent distribution subregion of a middle pressure network frame, is to make
To carry out the elementary cell that power distribution network " special " is planned for isolated area.
Use power grid：In geographical distribution, it is that several are adjacent, power supply grade is identical or close, right with power grid
Power supply reliability requires basically identical plot (or user) combination.Electricity consumption grid embodies final power consumer to power supply reliability
Differentiation require, be can the independent setting object of planning (power supply reliability) minimum for () electric unit.
Function grid：Function grid be one between distribution grid and with power grid between intermediate mesh, be one auxiliary
Distributed load prediction and grid structure allocation plan is helped to set up, have certain class common trait (or purposes), size appropriateness
, geographical space is continuous, can give the power supply area appropriately named.Under normal circumstances, in function grid and urban planning
Function division corresponds to.
Piece is got in touch between standing：According to power transformation station location and power load distributing, build for the object of planning by distant view " simply connected network between standing "
Circuit contact layout between vertical transformer station and power supply area.
Power supply unit：Power supply unit is one and can independently undertake this region normal power supply task (not crossfeed, and having
Have autonomous self-healing ability), (generally 1 group standard wiring, no more than 2 groups) power supply area of moderate scale, be one on ground
The combination of upper several access units continuous of reason distribution.
(2) distribution gridding planning system design
According to definition, " distribution grid " is the relatively independent electric power distribution network system of middle pressure network frame it is intended to strengthening distribution
" autonomous self-healing " ability in grid.After introducing " distribution grid " concept, power distribution network has just been simplified to one by several tools
The simple network system being made up of " autonomous self-healing " ability, relatively independent " distribution grid ", distribution net work structure obtains comprehensively
Simplify.Simultaneously as relative independentability, " distribution grid " is also one and can carry out " special " rule of power distribution network as isolated area
The planning unit drawn, thus, the also planning for power distribution network (containing electrical network, communication, automation, informationization etc.), construction, scheduling, fortune
Row brings brand-new idea of development.
According to existing power system management system, " send out, defeated, become, join, using " five links are divided into generatings, and (generating collects
Group), defeated change (grid company), three levels of distribution (electric company), in terms of planning angle, respectively corresponding power planning, major network
Planning, distribution planning three parts, wherein, distribution is planned after gridding, is decomposed into " power distribution network bulk transmission grid planning (high pressure
Power distribution network and the middle pressure interconnection of power distribution network compartment) " and " distribution grid plans (low and medium voltage distribution network within distribution grid) "
Two parts, thus, distribution network planning system (process and content) can be adjusted to：
1) need for electricity prediction (according to sectorization)：With municipal development plan (total rule, regulatory control) as foundation, with function division
For unit, to each function division need for electricity (land character, saturation loading density, year by year load growth rate, power supply reliability will
Ask) it is predicted, as the Main Basiss of stress and strain model；
2) distribution stress and strain model：Plan that (power distribution), function are divided with power distribution network present situation (middle pressure network frame independence), major network
Based on area's (need for electricity), by distribution grid and function mesh definition, in region-wide scope, consider as a whole, universal formulation
Distribution grid and function grid, and Unified number is carried out to grid；
3) grid search-engine coding：With " distribution network planning designing technique directive/guide " as foundation, predicted (by work(according to need for electricity
Can subregion), distribution and function grid division result, by power supply area classification, the attribute such as saturation loading density, load maturity,
Each grid search-engine is encoded, forms the system file of region-wide distribution network planning, be " special " planning of distribution including work done in the manner of a certain author
The distribution grid inventory of establishment, and define planned range and the planning depth of " planning of power distribution network bulk transmission grid "；
4) power distribution network bulk transmission grid planning：With the middle pressure interconnection of region-wide high voltage distribution network and power distribution network compartment with do not examine
The low and medium voltage distribution network that the distribution grid that distribution " special " is planned is made in worry is planned range, and with safe operation of electric network, power supply can
It is target by property etc., power distribution network bulk transmission grid rule based on power distribution, power balance, passage/institute's resource reservation of standing for the establishment
Draw；
5) distribution grid planning：With distribution grid as elementary cell, by electricity consumption mesh definition division power grid；With electricity consumption
Grid " differentiation " need for electricity is guiding, and with power supply reliability as target, establishment includes circuit contact, channel layout, communication
Mode, Automated condtrol, relaying configuration are in interior complete mesolow power supply plan；
6) " gridding " typical scenario storehouse：Intend unified organizational system, become with territorial classification of powering, saturation loading density, load
The grid search-engine such as ripe degree are applicability mark, modular, standardized typical design solution.
(3) Load Characteristic Analysis
Classified according to based model for load duration load nature of electricity consumed, electric load can be divided into：Continuous type of production (two, three class industrial lands),
Commerce services type (containing lands used such as commercial facility, culture, physical culture, universities and colleges), public service-oriented (health care, transport hub
Land used), residential (residential estate), routine work type (the other lands used outside above-mentioned 4 classes) 5 big class,
" residential " and " routine work type " plot electricity consumption have good electricity consumption and avoid the peak hour phenomenon.Meanwhile, from corresponding
When load characteristic curve can be seen that " residential " peak, " routine work type " load only has the 40% of peak load；And " day
During often work type " peak, " residential " load only has the 20% of peak load.
(4) region peak load Forecasting Methodology
According to load curve indicatrix, the load peak in a region must be occurred when day or night two is big
One of section, therefore, the needs that calculated with peak load in conjunction with planning, when we can calculate daytime and two peaks of evening respectively
The region peak load of section, and its maximum is taken as the planning calculating peak load value of one's respective area according to result.
" method is sought in black peak peak load superposition in vain " specific formula for calculation is as follows：
Pmax=MAX (P is white, and P is black)
Wherein：
P is white=∑ (the white i of Psumi*K) (i=1,5, i is " continuing load nature of electricity consumed type ")
P is black=∑ (the black i of Psumi*K) (i=1,5, i is " continuing load nature of electricity consumed type ")
Psumi=∑ (Pj) (j=0, n, j are the plot " continuing load nature of electricity consumed type " for i in region)；
Pj=plot j distant view load value；
The white i of K：I continues load nature of electricity consumed type daytime period load correction factor；
The black i of K：I continues load nature of electricity consumed type load correction factor the period in the evening.
According to typical load indicatrix, each " black period corrected parameter in vain " continuing load nature of electricity consumed type is as following table institute
State：
Table 1：Each " black period corrected parameter in vain " continuing load nature of electricity consumed type
| Sequence number | Continue load nature of electricity consumed | K is white | K is black |
| 1 | Continuous type of production | 1 | 0.9 |
| 2 | Commerce services type | 0.8 | 1 |
| 3 | Public service-oriented | 1 | 0.6 |
| 4 | Residential | 0.2 | 1 |
| 5 | Routine work type | 1 | 0.4 |
(5) distant view distributed load Forecasting Methodology
Advised in detail according to land used (total advise), and choose the load density target of respective horizontal and simultaneity factor is calculated distant view and divides
Cloth load prediction, collects the future load forecast result obtaining this region, large user in region is individually considered simultaneously.
The computing formula having the plot distant view load of planned land use is：
P=load density target * block area (without large user) * plot ratio * demand factor * simultaneity factor+∑ P large user
I (i=0, n, i are intramassif large user's sequence number).
Two：Town and country (tourist district) distribution network planning pattern
