Description

Evaluation method and device for energy-saving project of base station

technical field

The invention relates to the field of financial evaluation, in particular to a method and device for evaluating energy-saving projects of base stations.

Background technique

At present, the research on energy-saving projects of base stations mainly focuses on energy-saving and simple energy-saving benefits. From the perspective of technical research, there are generally two methods based on the principle of "with or without comparison": 1. Self-comparison A base station obtains the power consumption of a certain period of time after the implementation of the energy-saving project of the base station and the power consumption of the same period of time under the same climate conditions before the implementation of the project. Theoretically, it is believed that the difference between the two is the energy-saving project. Energy saving. 2. Set up a benchmark station, select two base stations with the same working conditions and the same climate location, and only one of the stations will undergo energy-saving renovation, and measure the power consumption of the two stations at the same time, then the base station that has implemented the energy-saving project The difference between the power consumption and the power consumption of the benchmark station is the energy saving brought by the energy saving project. It can be seen that the research on the energy saving of existing base stations relies on field measurements, and due to the large investment in metering of base stations, there is no large-scale popularization at present, and there is still a lack of reliable and long-term test data, which affects and restricts the post-evaluation work of energy-saving technologies . In addition, from the perspective of economic research, the current research on energy-saving projects in the communication field is relatively lagging behind. The economic models used are mainly in the form of investment cost and algebraic sum of income, without considering factors such as the time value of funds. Furthermore, due to the many factors affecting the energy-saving benefits of base stations, and the lack of attention of operating companies, relatively few studies have been carried out at present, and there is no reliable method to comprehensively analyze the entire life cycle of the energy-saving project of the base station as a whole. Evaluation studies. Moreover, because the existing technology cannot take into account the capital time value in the life cycle of the entire base station energy saving project in the evaluation work, this situation has led to the fact that the existing base station energy saving project will be profitable for a certain period of time when it is implemented. In fact, the entire base station energy saving project will be at a loss after the implementation, but due to capital depreciation over time and other reasons, the base station energy saving project will give people a false impression of profit, resulting in the comparison between the evaluation results of the base station energy saving project and the actual results. produce large errors.

It should also be noted that, in the embodiments of the present invention, "的 (English: of)", "corresponding (English: corresponding, relevant)" and "corresponding (English: corresponding)" can sometimes be used in combination. It should be pointed out that , when the difference is not emphasized, the meanings they want to express are consistent.

At present, the research on energy-saving projects of base stations is mainly focused on energy saving and simple energy-saving benefits, and the capital time value in the life cycle of the entire energy-saving projects of There is a large error in the comparison between the evaluation results of the project and the actual results.

In view of the above problems, as shown in FIG. 1 , an embodiment of the present invention provides a method for energy saving of a base station, which includes:

101. Obtain equipment parameters of energy-saving equipment in a base station energy-saving project, a life cycle of a base station energy-saving project, and historical data of a base station that has not implemented a base station energy-saving project.

Specifically, in the implementation of the base station energy saving project, because the base station energy saving project is to transform the equipment of the base station itself or use new equipment, the time required for the transformation of old equipment or the replacement of new equipment is relatively short compared to the operating life of the equipment. The term is very short, so in the actual base station energy saving project, the life cycle of the base station energy saving project is considered to be the operating life of the energy saving equipment used in the base station energy saving project; so although the life cycle of the base station energy saving project should include the construction period of the base station energy saving project It is composed of the life cycle of equipment improved or newly added by the base station energy saving project, but in the embodiment of the present invention, the life cycle of the base station energy saving project is selected as the operating life of the energy saving equipment used in the base station energy saving project; for example, considering Various hard factors industries stipulate that the operating life of energy-saving equipment is 8 years, that is, the life cycle of the base station energy-saving project provided in the embodiment of the present invention is 8 years.

102. Determine the evaluation factor according to the equipment parameters of the energy-saving equipment in the base station energy-saving project and the historical data of the base station that has not implemented the base station energy-saving project; the evaluation factor is a factor that affects the income of the base station energy-saving project.

Optionally, the evaluation factors include at least: the purchase cost of energy-saving equipment in the base station energy-saving project, the residual value rate of the energy-saving equipment in the base station energy-saving project, the construction cost of the base station energy-saving project, the annual operation and maintenance cost of energy-saving equipment in the base station energy-saving project, The annual energy consumption cost of energy-saving equipment in the base station energy-saving project. Here, the evaluation factor does not take a value, but only represents a category, which is used to establish a model. Only in the final evaluation, the corresponding value will be substituted into the final model for calculation.

103. Establish a TI-A rapid evaluation model based on the evaluation factors, the life cycle of the base station energy saving project and the preset minimum financial internal rate of return.

This step is the core of the entire base station energy-saving evaluation method. Here, the life cycle of the base station energy-saving project is fully considered in the establishment of the evaluation model, so that when the evaluation model is used to evaluate a base station energy-saving project later, the base station energy conservation can be considered more comprehensively. Project investment changes over time.

Specifically, the preset minimum financial internal rate of return for base station energy-saving projects is set at 10% in the industry.

104. Determine whether the base station energy saving project meets the TI-A rapid evaluation model. When the base station energy saving project meets the TI-A rapid evaluation model, determine that the base station energy saving project is qualified; when the base station energy saving project does not meet the TI-A rapid evaluation model, determine the base station energy saving project failed.

Specifically, judging whether the base station energy-saving project meets the TI-A rapid evaluation model is mainly based on the total investment and net cash flow of the base station energy-saving project to judge whether the capital payback period of the base station energy-saving project meets a minimum limit. Qualified base station energy-saving projects indicate It can be implemented, but unqualified base station energy-saving projects cannot be implemented. The specific implementation or non-implementation needs to be decided by the project planner according to the actual situation. The evaluation results are only used as an important reference.

The method for evaluating energy-saving projects of base stations provided by the embodiments of the present invention, because the method includes: acquiring equipment parameters of energy-saving equipment in energy-saving projects of base stations, life cycles of energy-saving projects of base stations, and historical data of base stations that have not implemented energy-saving projects of base stations; The equipment parameters of the energy-saving equipment in the energy-saving project and the historical data of the base station that have not implemented the energy-saving project of the base station determine the evaluation factor; the evaluation factor is the factor that affects the income of the energy-saving project of the base station; The internal rate of return establishes a TI-A rapid evaluation model; judges whether the base station energy-saving project meets the TI-A rapid evaluation model, and when the base station energy-saving project meets the TI-A rapid evaluation model, it is determined that the base station energy-saving project is qualified; A rapid evaluation model to determine that the energy saving project of the base station is not qualified. The evaluation method of the base station energy-saving project provided by the embodiment of the present invention firstly obtains the model-building method based on the historical data (such as annual energy consumption) of the base station that has not implemented the base station energy-saving project and the equipment parameters of the energy-saving equipment in the base station energy-saving project At the same time, the life cycle of the energy-saving project of the base station is also obtained, and then the existing financial evaluation method is used to combine the obtained evaluation factors, the preset minimum financial internal rate of return and the life cycle of the energy-saving project of the base station to establish a rapid evaluation of a A TI-A rapid evaluation model for judging whether the base station energy-saving project is profitable. The model established in this way not only considers the energy saving and energy consumption of the base station, but also considers the investment in the entire base station energy-saving project. In the case of depreciation or appreciation, the funds that occur in the future life cycle can be discounted to the construction period of the base station energy saving project to truly reflect the actual income of the base station energy saving project, so the technical solution provided by the embodiment of the present invention can fully consider the base station energy saving The time value change factor of the project not only simplifies the tedious evaluation process of the base station energy saving project, but also provides simple and clear evaluation criteria based on the evaluation model to ensure the investment effectiveness of the base station energy saving project and avoid invalid or unprofitable investment.

In order to more clearly illustrate the evaluation method of the base station energy saving project provided by the above embodiment, as shown in FIG. 2, the embodiment of the present invention also provides another evaluation method of the base station energy saving project, which includes:

201. Acquire equipment parameters of energy-saving equipment in the base station energy-saving project, a life cycle of the base station energy-saving project, and historical data of base stations that have not implemented the base station energy-saving project.

Specifically, for the acquisition of the life cycle of the energy-saving item of the base station, refer to the description in the foregoing embodiment, and details are not repeated here.

202. Determine the evaluation factor according to the equipment parameters of the energy-saving equipment in the base station energy-saving project and the historical data of the base station that has not implemented the base station energy-saving project; the evaluation factor is a factor that affects the income of the base station energy-saving project.

Specifically, for the types of evaluation factors, refer to the descriptions in the foregoing embodiments, which will not be repeated here.

203. Establish a total project investment model and a net cash flow model based on the evaluation factors.

Specifically, the total project investment model is as follows:

Wherein, TI is the total investment of the base station energy-saving project, n is the number of sub-items that need to be _invested in the base station energy-saving project, and Is is the investment in each sub-item in the described base station energy-saving project, such as the purchase cost of energy-saving equipment is I ₁ , the construction cost is I ₂ and so on; the cost of other sub-items can be deduced by analogy.

The net cash flow model is specifically:

A _t =E _1t -E _2t -M _t +I ₁ *R _z ;

Among them, A _t is the income of the t-th year after the implementation of the energy-saving project of the base station, E _1t is the energy consumption cost of the base station in the t-th year before the implementation of the energy-saving project of the base station, and E _2t is the energy consumption cost of the base station after the energy-saving project of the base station is implemented. The energy consumption cost of the t-th year, M _t is the operation and maintenance cost of the energy-saving equipment in the t-year, I ₁ is the purchase cost of the energy-saving equipment, R _z is the residual value rate of the energy-saving equipment, that is, the energy-saving equipment in the first year The percentage of the value lost due to use or the passage of time in the year t as a percentage of the initial purchase cost; net cash flow refers to the income of cash and cash equivalents minus expenditures within a certain period of time. In the embodiment of the present invention, the specific income and expenditures It can be not only listed in the above model, but also can be increased or decreased according to the actual situation.

It should be noted that each component of the model established in step 202 is an evaluation factor, and any change in the value of any item of the evaluation factor will affect the revenue of the base station energy saving project.

204. Establish the project payback period model, internal rate of return model and financial net present value model based on the total project investment model and net cash flow model.

Specifically, the project payback period model is specifically:

Wherein, _Pt is the investment payback period of the base station energy-saving project, and the project payback period can indicate the time required for the cost recovery of the base station energy-saving project; because when calculating the project payback period, the income situation of each year is mainly considered to determine the payback period, In the base station energy-saving project, the main income comes from the energy consumption saved by the energy-saving equipment, and the annual income fluctuation of the energy-saving equipment in the normal operation of its life cycle is very small, which can be approximately regarded as unchanged. Therefore, in order to facilitate the establishment of the project payback period model, generally default Net cash flow is the same every year.

The internal rate of return model is specifically:

Wherein, m is the number of years of the life cycle of the base station energy saving project, and the FIRR _s is the FIRR (Financial Internal Rate of Return) when the base station energy saving project does not generate energy saving benefits after the end of its life cycle When the FIRR is FIRR _s , it is the minimum standard for the implementation of the base station energy saving project. At this time, the base station energy saving project has no profit or loss.

The financial net present value model is specifically:

Wherein, FNPV (Financial Net Present Value, financial net present value) is the financial net present value of the energy-saving project of the base station; The financial net cash flow (net cash flow A _t in the embodiment of the present invention), converted to the sum of the present value at the beginning of the construction period (the beginning of the first year of the life cycle of the base station energy-saving project) according to a given standard discount rate; In the embodiment of the present invention, the meaning of the above sentence is that FNPV is an economic index that is evaluated by discounting the profit and loss in the entire life cycle at the time when the energy saving project of the base station is first implemented. Financial net present value is the main dynamic evaluation index to examine the profitability of a project in its life cycle. When FNPV is greater than 0, it means that the corresponding project is profitable. When FNPV is less than 0, it means that the corresponding project is in loss. When FNPV is equal to 0, it means that the corresponding project is neither profitable nor loss-making.

205. Establish a comprehensive evaluation model based on the project payback period model, internal rate of return model and financial net present value model.

Specifically, according to the corresponding formulas and meanings of the project payback period model, internal rate of return model, and financial net present value model, FIRR _s is the cumulative present value of net cash flow of each year in the life cycle of the base station energy-saving project equals to 0. Financial internal rate of return, FIRR is used to examine the profitability of the project. In a certain calculation period, if the actual FIRR is greater than FIRR _s , the project will have profitability. FNPV refers to the sum of the present value of the net cash flow of each year in the project calculator calculated when FIRR is set. The larger the FNPV value, the greater the profit of the project. _Pt refers to the time required to recover the project investment from the net income of the project, which reflects the fund recovery ability of the base station energy-saving project. The smaller the value, the greater the profitability of the project; so based on these, it can be concluded that the base station energy-saving project is qualified without loss A comprehensive evaluation model that meets the following three formula subcombinations:

206. Establish a TI-A rapid evaluation model based on the comprehensive evaluation model, the life cycle of the base station energy-saving project, and the preset minimum financial internal rate of return.

Specifically, according to the above (4), the life cycle of the base station energy saving project is 8 years and the preset minimum internal rate of return is 10%, (1)(2)(3) can be simplified to formula (5):

From the first formula in (5), it can be concluded that when FIRR takes the industry’s lowest value of 10%, TI/A _t = 5.33, that is, when the project payback period is 5.33 years, the FIRR of the base station energy-saving project is exactly 10% , at this time FNPV=0, which is the minimum standard for the implementation of the energy-saving project of the base station;

Can draw from the second formula in (5) formula, when FIRR=10%, At this time, TI/A _t ≤5.33, FNPV=0 and satisfy the formula of TI/A _t ≤8 at the same time; when FIRR>10%, TI/A _t ≤5.33, at this time, FNPV is greater than 0 and TI/A _t ≤8;

So in summary, when TI/A _t ≤ 5.33, it must meet the comprehensive evaluation model of the base station energy saving project, so the final evaluation model of the base station energy saving project is the TI-A rapid evaluation model:

TI/A _t ≤ 5.33.

207. Determine whether the energy saving project of the base station satisfies the TI-A rapid evaluation model.

When the base station energy saving project satisfies the TI-A rapid evaluation model, determine that the base station energy saving project is qualified, and execute 208; when the base station energy saving project does not meet the TI-A rapid evaluation model, determine that the base station energy saving project is unqualified, and execute 209.

208. Determine to implement the energy-saving project of the base station.

209. Adjust the energy saving project of the base station.

After 209, execute 201.

Specifically, when the total investment and net cash flow of a certain base station energy-saving project do not meet the above-mentioned TI-A rapid evaluation model, it can continue to model after adjustment and judge the implementation.

It should be noted that, in the above-mentioned embodiments, A _t is a fixed value for the convenience of calculation, that is, it is considered that the net cash flow does not change during the life cycle of the entire base station energy-saving project; in addition, in the above-mentioned embodiments, various The models are all based on the principle of "with or without comparison" to compare the base stations that have not implemented the base station energy-saving project with the base station that has implemented the base station energy-saving project. The economic indicators that best reflect the energy-saving benefits of the base station and the previous evaluation factors are obtained.

In the evaluation method of the base station energy saving project provided by the above embodiment, after obtaining the life cycle and evaluation factors of the base station energy saving project, firstly establish the total project investment model and net cash flow related to the energy saving income of the base station energy saving project by using the existing financial evaluation method Secondly, according to the project total investment model and net cash flow model, establish the project payback period model, internal rate of return model and financial net present value model, and then establish a comprehensive evaluation based on the project payback period model, internal rate of return model and financial net present value model Model, and then establish a TI-A rapid evaluation model based on the comprehensive evaluation model, the life cycle of the base station energy-saving project and the preset minimum financial internal rate of return, and finally can quickly judge whether a base station energy-saving project is qualified according to the TI-A rapid evaluation model implementation to judge. Because in the whole evaluation process, the project payback period model, the internal rate of return model and the financial net present value model based on the total project investment model and the net cash flow model all consider the time value of the base station energy-saving project, and then Based on these three models, combined with the life cycle of the base station energy saving project and the preset minimum financial internal rate of return, the TI-A rapid evaluation model is established, which not only takes into account the time cost of the base station energy saving project, but also can judge whether a base station energy saving project is qualified or not. It can make quick and accurate judgments on income, ensure the effectiveness of investment in base station energy-saving projects, and avoid invalid or unprofitable investments. Further, because the TI-A rapid evaluation model only needs the total investment of the base station energy saving project and the annual net cash flow to judge, the technical solution provided by the embodiment of the present invention can be used for the evaluation before the implementation of the base station energy saving project, and also It can be used to evaluate the energy saving projects of base stations that have been implemented.

In order to implement the base station energy-saving evaluation method provided in the above embodiments, referring to FIG. 3, the embodiment of the present invention also provides a base station energy-saving project evaluation device, which includes: an acquisition module 31, a processing module 32 and a judgment module 33;

Wherein, the obtaining module 31 is used to obtain the equipment parameters of the energy-saving equipment in the base station energy-saving project, the life cycle of the base station energy-saving project, and the historical data of the base station that has not implemented the base station energy-saving project; wherein the life cycle of the base station energy-saving project is the energy-saving the operating life of the equipment;
