Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Before the embodiment of the present invention is described, illustrate a kind of increment power distribution network in the embodiment of the present invention first matches somebody with somebody electricity price
The principle of the foundation of lattice forming method.
First determine the design principle of the distribution price forming method of increment power distribution network.First be the placing separation principle, increment
The distribution price design of power distribution network, realizes " the placing separation ", i.e., what the distribution price of increment power distribution network embodied is shared in principle
The price of distribution network, the price only share the power consumer and electricity of distribution network comprising increment power distribution network enterprise for all accesses
Source provides the price of distribution service, and the price of sales service and other services is provided a user not comprising the power distribution network owner.For
Meet the placing separation principle, before current increment power distribution network enterprise fails strictly to accomplish that the placing business is completely separated, for increasing
Power distribution network enterprise is measured, should accomplish that finance separation is separated with function.
Second is cost recovery principle, and the service that power distribution network provides belongs to public service.Under the principle of market economy, distribution
Network operation business wishes that it can be recycled conscientiously for the cost of investment of power distribution network, and can obtain being adapted to reason profit.Otherwise,
Distribution price is excessive, would be equivalent to levy taxes to distribution user, increases social cost；Distribution price is too low, it would be possible to increases wealth
Political affairs are subsidized, or even influence the quality of distribution service.Therefore, cost of compensation is one of Main Basiss of public product price, that is, is matched somebody with somebody
Electricity price should compensate reasonable cost and the expense expenditure that distribution network operation business occurs during distribution, power transformation.Meanwhile in order to protect
Hinder the capability of sustainable development of distribution network operation business and power distribution network, on the premise of stringent supervision, it should be ensured that power distribution network operation
Business can obtain reasonable benefit.
3rd is that performance and fairness is combined principle, and the selection of distribution pricing parameters should embody correlation, that is, be included in price
The expense of cost should be related to distribution service, meets cost input necessary to power grid operation.Power grid is typical public money
Source, public network distribution price should follow market efficiency principle, reduce tranaction costs and bargaining cost, play government again and exist
The guiding function of market price, ensures good service and the security provisions of distribution system, realizes distributing rationally for energy resource.Match somebody with somebody
The formulation of electricity price lattice should may advantageously facilitate power distribution network enterprise and improve production efficiency, including operational efficiency and efficiency of investment, with to the greatest extent
Possible low price provides a user safe and reliable quality services.The cost is relatively high for power distribution network, if not paying attention into this section
To about larger waste be caused.Therefore the selection of distribution pricing parameters will also be conducive to the saving of distribution cost.Meanwhile science,
Rationally, effective price signal will make different voltages grade and different classes of user's rationally to reflect distribution cost with electricity price,
And ensure universal electric service.
4th is to determine the principle of classification of increment power distribution network, initial stage is opened in increment power distribution network project, with mark post method
Determine based on distribution price, treat that relevant cost-price supervision data accumulation enriches degree to certain, supervision department has the ability pair
Different regions, different types of power distribution network cost and price are compared, assess after, can further improve mark post method.For
Different types of power distribution network project, distribution price need to consider the voltage class of power distribution network, class of subscriber, regional development situation etc.
Factor, is treated with a certain discrimination, Rational choice pricing parameters.
From above principle, the price of increment power distribution network should can promote power distribution network healthy and sustainable development, safely may be used
By power supply, the needs of all types of user development are disclosure satisfy that again, make the distribution price of different voltages grade and different classes of user
It can rationally reflect distribution cost.
From engineering experience, economic development level, the load characteristic of electric network composition and power grid and geographical conditions can
Leading role is played to the investment of increment power distribution network and operation cost.Under equal conditions, economically developed region increment power distribution network enterprise
Construction cost be higher than the power grid enterprises in economics of underdevelopment region, the voltage class of increment power distribution network, line length, become capacitance
Amount, electricity sales amount, reliability and number of users etc. also directly influence operation cost and income, and geographical conditions are related to for area
Area, user density, load density, landform, weather etc., therefore when formulating distribution mark post, can according to economic development level,
The principal dimensions such as Distributing network structure, geographical conditions, to increment power distribution network, enterprise classifies, specific as follows：
(1) classification rationally designs stake electrovalence, i.e., according to the distribution in each province and city, each department, variant type, it is reasonable to carry out
Distinguish, take into full account that the actual conditions of all kinds of distributions distinguish, rationally calculate average unit cost, and design component voltage grade, divide
The classification mark post of user type, is responsible to define by provincial competent pricing department in principle.
(2) using classification averaging method, mark post distribution price is determined.Provinces and cities carry out power distribution network enterprise where being proposed with
Classification, determines mark post distribution price, i.e. mean benchmark method according to the average level of similar power distribution network enterprise, so contributes to run
Less efficient power distribution network enterprise lifting management level.
(3) respect reality, take into full account the existing terminal electricity price in distribution location, rate for incorporation into the power network, provincial power network power transmission and distribution
Valency, bulk sale electricity price, local economic development demand, alternative subsidy, and distribution average unit cost, rationally calculate the mark post electricity of distribution
Valency.
(4) pricing Regulation mechanism, stake electrovalence is before each supervision cycle starts, by the government department having permission
After being responsible to define and examining, the distribution price as the supervision cycle is performed.Before next supervision cycle, the political affairs that have permission
Mansion department can be according to the traffic-operating period of increment power distribution network enterprise, and actual distribution construction operation cost, to next supervision week
The stake electrovalence of phase carries out price adjustment, can also cancel stake electrovalence, switchs to allowance income approach and is fixed a price again.
Distribution asset allocation addressed below.
Distribution assets are related to defeated, change, with each link, cover primary equipment, secondary device, and information-based, Department of Automation

It is engaged in relevant production cost and administration fee, selling charges, period expense only adjusts financial expenses.Since power transmission and distribution business has
Whether there is the product and manufactured inventory the characteristics of, adjusted using absorption costing will not affect that financial position of the enterprise and manage into
Fruit it is fairness.Power transmission and distribution cost is arranged to a producting cost accounting object, and power transmission and distribution cost objective divides into fee of material, worker
The items of cost such as emolument, depreciation cost, price for repairing, rural power expense, other fees.In addition to production cost, distribution operating cost also wraps
Include tax and add.Power grid enterprises not yet separately adjust Transmission Cost and distribution cost, also do not press voltage class and user class
It Fen Lei not adjust.
The calculating of asset pricing cost will also meet transmission ＆ distribution in addition to meeting the requirement of accounting standard and trade accounting system
Correlation and principle of reasonableness described in electric cosxts involved in determining price supervision and examination method.
Power distribution network enterprise manages distribution service mainly, electric energy is dispensed at power consumer from power transmission network or power plant, to electric power
User collects transmission charges (contemporary to receive and dispatch electricity, the expense of transmission of electricity link and every government fund and add).Transmission charges
Different prices is applicable in by different voltages grade and class of subscriber.Transmission of electricity enterprise receives super-pressure/high pressure from power transmission network or power plant
Electric energy, is distributed or distributes to all types of user step by step by voltage, the electric energy of a certain voltage class is allocated on the spot by distribution facility
To the user of the voltage class and the power distribution network of low voltage grade.Power distribution network is the Main Management assets of power distribution network enterprise,
