When, electric power green color index but seems smaller, lacks a kind of intuitive, in order to more preferably allow manager to understand the green shape of current power plant
Condition, we are innovative to construct a set of electric power green color index Grade Model.We are for air quality index first ---
PM2.5 Grade Model is studied, then portrays different grades of difference based on the principle of linear equal difference, and last we distinguish
Choosing two has the time of reference value as Grade Model datum mark, is verified finally by the emission reduction targets for substituting into the year two thousand twenty
Model, checking model can preferably divide electric power green color index.Specific method is as follows：
(1) electric power greenness grade is divided
We have investigated daily life and have often touched air quality grade, and the Grade Model is recognized extensively, have more
It is accurately descriptive, while modular concept is relatively simple, need to only determine basis of reference value and superposition linearly interval, have stronger
Operable row.Based on air quality grade model, we electric power greenness divide also for " excellent ", " good ", " slight pollution ",
Five grades of " intermediate pollution ", " serious pollution ", as shown in Figure 1.
(2) linear electrical green Grade Model is calculated
One linear electrical green Grade Model is mainly formed with two parts, and the datum mark and value with typical meaning close
The interval range of reason, overall linear Grade Model just can probably be determined by two above condition.Confirmation for datum mark
It is slight pollution and intermediate pollution that we, which have chosen environmental pollution improvement's first year in 2005 as our electric power green improvement starting points,
Between critical value, and another a reference value then chooses national environmental protection portion and has promulgated that newest thermal power plant's air is dirty in July, 2011
It is the good critical value between slight pollution to contaminate thing discharge standard (GB13223-2011), represents the specification that power industry is passed through 6 years
Administer, electric power greenness steps into a new height, reaches criterion of acceptability.Two typical reference points on passage time latitude,
We calculate each datum mark N by foregoing electric power greenness model0Greenness, then with relatively 2 points of spacing, draw electric power
The interval range λ of green grade.
1. the greenness of calculating benchmark point
Datum mark one, the total electricity volumes annual from State Statistics Bureau's export 2005, the total consumption of coal of power industry and then
The emissions data of various pollutants；Datum mark two, promulgate that newest thermal power plant is big in July, 2011 with reference to national environmental protection portion
Gas pollutant emission standard (GB13223-2011), wherein clear stipulaties the major pollutants SO of power plant emission2、NOX, powder
The concentration limit of dirt is ρ respectivelyl1=200mg/m3、ρl2=100mg/m3、ρl3=30mg/m3.For the carbon emission of power plant, at present
China is also without clear and definite limit standard, and the present invention is using EPA in the carbon emission standard of issue in 2012：It is required that electricity
Factory CO2Discharge capacity be no more than 450g/kwh, i.e.,Again total electricity volume in 2011 is exported from State Statistics Bureau
And smoke discharge amount, it is possible to try to achieve the discharge capacity total amount of carbon and each pollutant then.
The data for being known as and closing datum mark one, two are searched from State Statistics Bureau, by quantifying the environmental value of carbon and emission, from
And electric power greenness model is constructed, wherein it not is single power plant that the present invention has selected the ensemble average in the whole nation horizontal when calculating,
So it is considered that the outsourcing part of station service is 0, while station service power consumption rate also takes average national level then, result of calculation is such as
Following table
Table 2No bench mark datas and calculating
2. computation interval scope
After the known datum point electric power greenness of 2005 and 2010, so that it may it is big further to calculate single interval range λ
It is small.Calculation formula is as follows：
λ=0.41 (20)
Wherein for the benefit of understand and avoid unnecessary calculating interval range of the present invention from taking approximation as follows：
λ≈0.40 (21)
It is determined that after the datum mark No and interval range λ of electric power green Grade Model, can be extrapolated by linear combination
The division of whole electric power greenness grade, result of calculation such as following table.
The thermal power plant's electric power green Grade Model of table 3
3. verify electric power greenness Grade Model

Agree unanimously and pass through in change conference《Reach an agreement in Paris》, made arrangements for whole world reply climate change action after the year two thousand twenty.And increase
Add to the year two thousand thirty, the CO2 emission of unit GDP and declined 60%-65% promise than 2005.With the promise
Based on, the CO2 emission of our equal proportion limitation electric power enterprises, then extrapolate power industry from the discharge water level
Unit norm coal consumption amount, assuming that pollution handling process subversive improvement did not occurred in nearly 15 years, be maintained at previous level
It is constant, the generated energy of the gross contamination emission and thermoelectricity under current coal consumption can be extrapolated, based on the energy with reference to developed country
Source structure, it is believed that coal electricity generated energy 30% or so and station service power consumption rate maintain 2% or so be for energy resource structure it is optimal, further
2030 power industry gross generations are extrapolated, finally calculate the electric power greenness GPI under ideal conditions.
The CO2 emissions of dreamboat lower the year two thousand thirty, equation below：
CP2030=CP2005(1-60%) (22)
The anti-burning formula for pushing away carbon can be obtained again, and the standard coal consumption of thermoelectricity, as follows under the carbon dioxide emission targets
Formula：
Wherein CP represents carbon emission amount, EnCoal consumption figure is represented, k represents the efficient oxidation fraction, and n represents standard coal per ton
Phosphorus content, the calculating parameter of different energy sources kind difference.
Under ideal conditions, the thermal power generating equipment of power industry is run in optimum state, and standard coal per ton is arranged with pollutant
Put object amount and generated energy is in direct ratio, its ratio is constant ri(i=1,2,3,4 ..., n represents SO respectively2、NOX, dust etc.)
With constant s, the total amounts of all kinds of discharges is obtained respectively, then weighted accumulation tries to achieve direct environment value, is denoted as Vd2030Always sent out with calculating
Electricity Q2030, equation below：
Wherein ωiThe environmental value of i-th kind of pollutant is represented, unit is member/kg.
Q2030=Ens/k (25)
Wherein k represents the proportion that coal electricity accounts for power industry generating total amount, under ideal conditions with reference to developed country's electric power row
Industry structure takes 30%.
The indirect environmental value under ideal conditions is calculated again, is denoted as Vi2030；Finally, estimated data is arranged and by 4 constructions
The year two thousand thirty electric power greenness, equation are as follows：
Vi2030=kQ2030·CE2030 (26)
Wherein k represents station-service synthesis station service power consumption rate, and 2% is taken under the optimal running status of unit；CE2030Represent preferable shape
The carbon and the environmental value of pollutant that unit quantity of electricity directly discharges under state.
Finally, the year two thousand thirty electric power green model is drawn by arranging approximate calculation, as a result such as following table：
The target power green data of table 4 and calculating
It can be seen that China will realize the energy conservation object of the year two thousand thirty, it is necessary to carry out management supervision, a side in terms of two
Face is to improve the overall energy resource structure of industry, reduces thermoelectricity proportion shared in whole electric power；The ring of another aspect generating set
The emission control effect that guarantor's equipment updates pollutant is become better and better, and it is 12.8% finally to estimate GPI, its electric power green grade
To superior.Simultaneously this just demonstrate the present invention electric power green Grade Model can effectively with intuitively divide the different discharge of power plant and anti-
Historical trend is changed over time, current environmentally friendly situation and electric power green intensity to manager's visual understanding enterprise.

Understood in 5, the carbon of power plant 1 and the discharge capacity of pollutant are significantly lower than power plant 2 and power plant 3, and power plant 2 also can obtain thermal power plant simultaneously
The carbon directly discharged has a significant impact with pollutant value to electric power green color index；Carbon and pollutant discharge amount between power plant 3 are most
Greatly, this shows the discharge capacity of carbon and pollutant and final comprehensive evaluation result into inverse correlation, the run in carbon put and pollutant
Environmental value is minimum, but final electric power green color index still is below power plant 1.From table 7 and table 6 it can be seen that selected by the present invention
Three power plant be in a leading position level in terms of control carbon and pollutant emission, electric power green grade is excellent.
As can be seen from Figure 2, main cause is that the carbon that discharges indirectly and pollutant value are relatively low, while is also illustrated in thermoelectricity
The carbon and the environmental value of pollutant directly discharged in factory's electric power Green Evaluation is than the carbon discharged indirectly and the environment valency of pollutant
Weight is bigger shared by value, and electric power green color index is had a great influence, and wants to lift thermoelectricity electric power green color index, passes through technological improvement
Reduction pollutant directly discharges more efficient；At the same time, it should also which the thermal power plant for encouraging environmental protection facility incomplete passes through outsourcing
