Below in conjunction with accompanying drawing, content of the present invention is further described.
As shown in Figure 1, the present embodiment provides a kind of intelligent analysis method of Electricity customers electrical network access point, specifically comprises the steps:
S1 receive Electricity customers apply to install information; Described information of applying to install comprises and applies to install address, applies to install type, applies to install capacity and synchronous coefficient;
S2 according to described in apply to install the anchor point determining on map in address, apply to install type according to described, within the scope of the appointment search radius of described anchor point, search meets pre-conditioned access point apparatus;
S3 obtains and applies to install customer information in transit from marketing system, from metering automation system, obtain described access point apparatus intend the historical data of access according to described type of applying to install, and according to described apply to install customer information in transit, described historical data and described in apply to install type, apply to install capacity, synchronous coefficient calculates access place of described plan and accesses the maximum load rate after described access point apparatus;
S4 judges whether described maximum load rate is less than or equal to threshold value; If so, then S5 is entered;
S5 is using the stand-by equipment of access point apparatus corresponding for this maximum load rate as Electricity customers.
In marketing system, what store Electricity customers applies to install information, comprises applying to install address, apply to install capacity, applying to install type, synchronous coefficient etc., wherein applies to install type and comprises middle pressure and low pressure.Industry expand auxiliary apply to install that system obtains Electricity customers from marketing system apply to install information, then carry out Orientation on map according to the address of applying to install of this Electricity customers, determine anchor point.If apply to install address coordinate form (i.e. longitude and latitude form), then can directly position on map; If apply to install address street address, number and so on, then can according to this address in conjunction with adjacent table number and distribution account reconnaissance location on map.After determining anchor point, can according to appointment search radius, apply to install type and carry out topological analysis, search meets pre-conditioned access point apparatus.
Concrete, if applying to install type is middle pressure, access point apparatus comprises loading switch cabinet and middle depression bar tower, wherein loading switch cabinet is a kind of electric equipment, master switch and sub-control switch is comprised in this loading switch cabinet, outside line is introduced into master switch in loading switch cabinet, then enters sub-control switch, each along separate routes by the setting of its demand; Middle depression bar tower refers to that electric pressure is the overhead line structures of 10kV (sometimes also getting 6kV or 20kV), and in each, depression bar tower has it to number.In appointment search radius, search for loading switch cabinet and middle depression bar tower, wherein for loading switch cabinet, require that it is empty cupboard or the non-leading-out wire of existing switch; For middle depression bar tower, search for its numbering.
If applying to install type is low pressure, access point apparatus comprises low-voltage cabinet, low pressure shaft tower, low-pressure line-outgoing switch and low pressure access point, and wherein, low-voltage cabinet is a kind of electric equipment, according to the feeder number of outlet, low-voltage cabinet has to enter four to go out into scene 2, one enter six and go out three kinds of forms; Low pressure shaft tower refers to that electric pressure is the overhead line structures of 380V or 220V, and each low pressure shaft tower all has it to number; Low-pressure line-outgoing switch refers to the switchgear of low-voltage cabinet outlet; The ammeter box of low pressure access point unified installation under comprising community, building or ammeter, also comprise virtual point, for accessing the low-voltage client of multiple dispersion on map.Low-voltage cabinet, low pressure shaft tower, low-pressure line-outgoing switch and low pressure access point is searched in appointment search radius; Wherein for low-voltage cabinet, require that it is empty cupboard or the non-leading-out wire of existing switch; For low pressure shaft tower, search for its numbering.
Then obtain from marketing system and apply to install customer information in transit, from metering automation system, obtain access point apparatus intend the historical data of access according to applying to install type, and according to described apply to install customer information in transit, described historical data and described in apply to install type, apply to install capacity, synchronous coefficient calculates access place of described plan and accesses the maximum load rate after described access point apparatus
Wherein, the customer information in transit that marketing system provides comprises the capacity of applying to install of client in transit and the synchronous coefficient of correspondence.When Electricity customers to apply to install type be middle pressure time, described historical data is the day maximum current that described access point apparatus intends access feeder line, calculates the maximum load rate of this feeder line after access point apparatus access feeder line by the following method:
(1) analog computation access point apparatus intends the load after accessing feeder line (i.e. the feeder line at access point apparatus place) new access Electricity customers and client in transit, specific formula for calculation:
Wherein, P
new clothescapacity is applied to install, S for described Electricity customers
new clothesfor the synchronous coefficient of described Electricity customers,
represent the cumulative sum of the capacity of applying to install of all clients in transit and the product of corresponding synchronous coefficient.
