Embodiment
The present invention is further described with reference to embodiments.
At present, steam power plant of China pollutant emission mainly includes：Steam power plant directly discharges and broad sense carbon emission.In order to heat
Power plant's electric power green color index model is built, it is necessary to which discharge direct to steam power plant and broad sense carbon emission quantify.Quantization side
Method is as follows：
1st, the quantization that steam power plant directly discharges
What the fuel that the pollutant emission rate in steam power plant's production process specifically refers to burning unit mass was emitted
The total amount of pollutant.Announced according to Environmental Protection in China office《Emission standards of air pollutants for coal-fired》, choose sulfur dioxide
(SO2), carbon dioxide (CO2) and nitrogen oxides (NOX) etc. major pollutants analyzed, carried out below with this several pollutant
Measuring and calculating evaluation steam power plant electric power greenness.
Emission mathematical symbolism is as follows：
Qi(i=1,2,3,4 ..., n represents SO respectively2、NOX, dust, solid waste, waste water, other)
It is understood that the carbon of steam power plant's discharge can bring different degrees of harm with pollutant to environment, and in governance process
In will produce different treatment costs, the present invention using the per unit treatment cost of pollutant as their environmental value, with
This establishes the environmental value weight of pollutant；Therefore the environmental value proportional system constructed by pollutant that steam power plant discharges is such as
Under：
ωi(i=1,2,3,4 ..., n represents SO respectively2、NOX, dust, solid waste, waste water, other)

1.5 yuan/kg
Wherein ω1、ω2、ω3、ω4、ω5、ω6SO is represented respectively2、NOX, dusting solid waste, the environmental value of waste water.
2nd, the quantization of broad sense carbon emission
China's fossil energy consumption is based on coal, and the consumption of coal that the whole nation accounts for half is used to generate electricity, most in the past 10 years
Accounting is more than 80% in China's electricity consumption structure for coal electricity, and CO2Make the main carbon emission thing of coal electricity.Under present condition,
The basic data that steam power plant's carbon source calculates is lacked, direct measuring difficulty is very big.To this, our evaluation methods of use are mainly
According to 2006 Intergovernmental Panel on Climate Change (IPCC) be UNFCCC and capital
The reference method that national greenhouse gases inventory guide volume Two (energy) chapter 6 that all protocol is formulated provides, carbon dioxide
Total emission volumn CO2 emission estimator can add up to obtain according to caused by various energy-consumings.
And the CO2 emission of power generation industry is specifically estimated, then carried according to U.S. Oak Ridge National Laboratory ORNL
Go out and CO is discharged according to combustion of fossil fuel2Calculating method estimates that carbon emission amount calculation formula is
CP=Enkn44/12 (1)
Wherein CP represents carbon emission amount, EnEnergy consumption 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.
There is no CO in China's Pollutant discharge levy criterion2Charge item, but this does not indicate CO2It is not belonging to pollutant, CO2Not only make
Into global warming, greenhouse effects are caused, discharge state is returned and brings certain economic loss.Therefore we should borrow
The environmental value standard in the mirror U.S., estimate the CO of China2Environmental value.According to CO2Relative to the value percentage of other pollutants
Than calculating CO2In the environmental value set of China, minimum value is taken as Chinese CO2Estimate, estimated using formula (2)
Calculate：
In formula, V (CO2) it is Chinese CO2Environmental value estimated value, Vi、PiIt is pollutant i respectively in China and the U.S.
Environmental value, P (CO2) it is U.S. CO2Environmental value.According to the Chinese CO of U.S. environment value estimate2Value is as shown in table 1.
1 Chinese CO of table2Environmental value estimation result
It can be calculated by table 1 and formula (2), Chinese CO2The estimated value of environmental value take 0.0041 yuan/kg.
Based on above quantized data, the construction method of steam power plant's electric power green color index model of the invention includes following step
Suddenly：
The environmental value of step 1, the carbon that calculating steam power plant directly discharges and pollutant
Traditional steam power plant's data monitoring cycle length, the index of data monitoring is not comprehensive, can not timely and effectively reflect heat
The real-time Green Development effect of power plant, for the problem, we select brand-new on-line monitoring system, and the system is with some points first
Zhong Weiyi minimum period TminThe carbon and pollutant emission data of each thermoelectricity unit are collected, then these data are carried out pre-

Critical value between dye, and another a reference value then chooses national environmental protection portion and has promulgated newest thermal power plant's air in July, 2011
Pollutant emission standard (GB13223-2011) is the good critical value between slight pollution, represents the rule that power industry is passed through 6 years
Model is administered, and electric power greenness steps into a new height, reaches criterion of acceptability.Two typical references on passage time latitude
Point, we calculate each datum mark N by electric power greenness model0Greenness, then with relatively 2 points of spacing, show that electric power is green
The interval range λ of colour gradation.

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 (38)
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 (39)
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.
