The project began to promote the project in an all-round way from the formulation of energy efficiency standards, application testing, expansion of media promotion, implementation of regional promotion, production of promotional materials, establishment of lighting websites and implementation of system certification. One of the most important tasks in these many projects is to save a lot of lighting power through the above activities. Therefore, correct and comprehensive statistics and calculation of the power-saving effect and economic benefits of China's green lighting project have far-reaching and long-term significance for correctly evaluating the value of China's green lighting project, and are also the most important topics for research and development of China's green lighting project. one.

1 Calculation method of power saving effect 1.1 The power saving effect of China Green Lighting Project consists of the following three aspects: power saving caused by the reduction of terminal power consumption; power saving caused by power supply and distribution and line loss reduction; Power savings from reduced peak power consumption.

1.2 Calculation method of power saving effect (1) Power saving caused by reduction of terminal power consumption High-efficiency energy-saving lighting products are used instead of power-consuming products for lighting, that is, ordinary lighting self-ballasted fluorescent lamps are used instead of ordinary lighting bulbs; Replace the fluorescent high-pressure mercury bulb with sodium lamp, high-pressure sodium lamp and metal halide lamp; replace the T12 straight tube fluorescent lamp with T5, T8, T9 and T10 straight tube fluorescent lamps; replace the same-type magnetic ballast with electronic ballast for illumination, The power consumption of the power supply terminal can be greatly saved, and the saving amount can be calculated by the following formula: 1. AE is a reduction lamp for the power consumption of the line terminal during the statistical period; 5, a straight tube fluorescent lamp of T8, T9 and T10 type; a high pressure sodium lamp, a low pressure sodium lamp And metal halide lamps; various types of electronic ballasts to replace the power consumption of various types of power consumption products, unit 1tfkWh. In 1, a single item of energy-saving lighting electrical products, according to the specification to achieve the savings: Ae is The energy saving of a single energy-saving lighting electrical product calculated according to the specifications, in kWh; a, is the social consumption of a certain energy-saving lighting product during the statistical period, its value The calculation is performed by one of the following two methods: Method () Direct calculation The direct calculation method is calculated based on the sample survey data of household users and large users on the consumption of energy-saving lighting electrical products, and the social usage can be calculated by formula 3. :Statistical data of statistical bureau, unit: one; d is the average usage of household users in the statistical area, given by sample survey data, unit: only / one; e is the number of large users in the statistical area, unit: one; j The average usage of large users in the statistical area, unit: only / one.

Both e and j are given by survey statistics.

Method (2) Cumulative method The cumulative method is a cumulative calculation of the annual social net amount of energy-saving lighting electrical products. The social consumption of a single energy-saving lighting electrical product during the statistical period is the sum of the net amount provided to the society during the effective life of the product. The value can be determined by the formula 4 Chinese lighting electrical limit factor, and its value is d=V/QV. The limited service life of a certain specification energy-saving lighting electrical products, unit: year; Q is the average number of hours of use of a certain specification of energy-saving lighting electrical products, its value Q = 365hi, unit: hour; Aj is a certain period of energy-saving lighting electrical products produced during the statistical period Annual net social consumption. According to the principle of "sales by sales" and "production and sales balance", the annual net social consumption of a certain specification of energy-saving lighting electrical products during the period of statistics is the annual production of energy-saving lighting electrical products of this specification plus annual import volume minus annual export volume. And, namely: quantity, unit: only; B is the annual import volume of energy-saving lighting electrical products of a certain specification, unit: only; C is the annual export volume of energy-saving lighting electrical products of a certain specification, single case 1: know the effective life of 400W high-pressure sodium lamp V =24000h, the average ignition time per year is Q=365X8=22, then A, the expansion formula is: Example 2: 13W self-ballasted fluorescent lamp has a limited life V=4380A, and the average ignition time per year is Q=365X4=1460h,d =V/Q=3, then the expansion of A, is: 1.3 The calculation of the item when calculating the statistics of a certain specification of energy-saving lighting electrical products in the society, a, the number of items of the expansion item is determined by the product of the specification Statistical calculations are determined annually. That is: only one item is taken in the first year of calculation, and two items are taken in the second year, but it can only be calculated up to d years.

For the power saving power of a single lamp of a certain specification, that is, when the luminous flux is the same, the difference between the power Pi of a certain specification power consumption lighting product and the power Pu of the energy-saving lighting product (for the illumination source) or the unit power electric light source Q is the green lighting engineering influence coefficient. , which represents the percentage of the annual quantity of a certain size of energy-saving lighting electrical products due to the impact of green lighting projects. This value is derived from the social sample survey. The single At. is the net social consumption in the current year. Unit: only; Ak* is the net social consumption in the year before the statistics. Unit: only; Ak.i is before statistics The net society generated in two years, the unit: only; 1) the net social production in the year, the unit: only. Discussion of d value: (() When d is the lower integer, the expansion formula takes the number of items of the integer value; the (integer value + 1) term, but the last term should be multiplied by the decimal point of the value The difference between the power loss of the used ballast and the electronic ballast (for the ballast) unit: W; for the high-efficiency lighting, the ratio of the light utilization factor of the same kind of efficient and inefficient lighting, unit: %; 365 For the number of lighting days per year, if the time of statistical calculation is not one year, the number can be changed to the actual number of days used; a, which is the average daily lighting time, and the actual survey data is calculated for the light source of different lamp types and uses. Accurate, can also be calculated according to low-intensity discharge lamp 5A per day, high-intensity discharge lamp 8A per day, unit: A; n is the total number of specifications of various energy-saving lighting products calculated by statistics; j is the statistical calculation of certain energy-saving lighting products Representative specifications.

In 1, if it is difficult to calculate according to the specifications, it can be calculated according to the variety. At this time, the power consumption of the “representative specification” can be used instead of the average power consumption of each specification product. At this time, the power saving of each individual energy-saving lighting product can be simplified by Equation 6: power, unit: kWh; During the period, the consumption of individual energy-saving lighting products, A, is calculated according to the actual survey data, and can also be calculated according to the low-intensity discharge lamp 5h every day, high-intensity discharge lamp 8h every day; n is the statistical calculation The total number of specifications for energy-efficient lighting products.

(2) Savings due to reduction of transmission and distribution losses Due to the reduced terminal load of the power supply line, the transmission and distribution power loss will inevitably decrease, and the savings brought by it can be calculated as follows: æ°“7m2 is the transmission and distribution loss coefficient of the power grid. , m2=0. 07; m3 is the terminal distribution loss coefficient, m3=0. (3) reduce the peak power consumption, because the lighting power is mostly in the peak period of electricity consumption, so the lighting power saving will inevitably bring To save on peak electricity consumption. The peak power saved can be calculated as follows: Ae is the power saving brought by the power supply terminal during the statistical period, and the calculation method of the single 2 economic benefit can be saved by the formula 9 due to the saving of the electricity consumption. Calculation. The savings consists of three parts, namely the savings brought by the reduction of terminal power consumption, the reduction of transmission and distribution losses and the reduction of peak power consumption. The specific calculation can be calculated as follows: savings, unit: yuan U is a weighted electricity price, which consists of three parts: the residential lighting price, the lighting price of industrial and commercial enterprises, and the street lighting price. The U value is between.

AV is the power cost saved by the power supply network, in kWh; the savings caused by the reduction in peak power consumption, in kWh; the calculation data of the power saving effect and economic benefit of China Green Lighting Project is obtained through statistical investigation. of. The calculation scope of its main statistical survey elements includes the output of various energy-saving lighting products, the average daily ignition time, and the average price of electricity used by civil, industrial and commercial enterprises. The survey statistics can be professional and comprehensive statistical departments, manufacturing plants. Business enterprises, large users and individual consumers. The survey data should be representative and quantitative basis, and the errors in the calculation results of power saving and economic benefits mainly depend on the errors of the above factors.
