[0047] Example 1

[0048] like Figure 1 As shown, this embodiment provides an energy-saving evaluation method for energy-consuming equipment based on the entire life cycle, including the following steps:

[0051] 1.1.1) Based on the rated efficiency η of the energy-consuming equipment provided by the manufacturer, calculate the shaft power P of the energy-consuming equipment. 轴功率 :

[0052] P 轴功率 =P 输出 / η(1)

[0053] Among them, P 输出 It is the energy provided by the equipment to the outside world per unit time; η can be considered for efficiency reduction based on the actual operation of the energy-consuming equipment.

[0054] 1.1.2) According to the shaft power P of each energy-consuming equipment 轴功率 The annual power consumption W of energy-consuming equipment of different manufacturers is calculated based on the annual operation time T of pipeline transmission capacity. 电 :

[0055] W 电 =P 轴功率 ×T(2)

[0056] 1.2) Considering that the efficiency of equipment decreases year by year, the annual power consumption W of energy-consuming equipment provided by different manufacturers is calculated. 电 Make corrections to obtain the corrected annual power consumption of the equipment W 电t :

[0057] W 电t =W 电0 ×(1-α) t (3)

[0058] Among them, W 电0 is the initial annual electricity consumption; α is the annual attenuation rate of equipment efficiency; t is the number of years the project has been in operation.

[0060] E 电t =W 电t ×C 电费t (4)

[0061] Among them, C 电费t The annual electricity charges are adjusted according to the forecast results of future change trends.

[0062] 2) The annual electricity cost E of each energy-consuming equipment during its entire life cycle 电t Discounted to the initial investment year (i.e. the first year of project operation), the discounted value PV of the operating cost of each energy-consuming equipment is obtained 运行 :

[0063] PV 运行 =∑E 电t ×(1+i) -t ,t=1,……,n (4)

[0064] Where i is the benchmark rate of return and n is the design life of the equipment.

[0065] 3) Based on the initial investment C of each energy-consuming equipment 设备 and the discounted present value (PV) of operating costs 运行 , determine the total cost present value NPV of each energy-consuming equipment, and select the plan with the lowest total cost present value as the optimal plan.

The shaft power of equipment from different manufacturers is calculated to be 1741kW and 1703kW respectively. Assuming the annual attenuation rate of the equipment is 0, the corresponding annual electricity bills over the entire life cycle are 9.15 million yuan and 8.95 million yuan respectively.

[0071] 2) The annual electricity cost E of each energy-consuming equipment during its entire life cycle 电 Discounted to the initial investment year, the discounted value of the operating costs of each energy-consuming equipment is obtained:

[0072] Based on the annual electricity charges calculated in step 1), and assuming a 25-year design life and a benchmark rate of return of 9%, the discounted present value of electricity charges corresponding to equipment from different manufacturers is RMB 88.81 million and RMB 86.88 million, respectively.

[0073] 3) Based on the initial investment C of each energy-consuming equipment 设备 and the discounted present value (PV) of operating costs 运行 , determine the total cost present value (NPV) of each energy-consuming equipment, and select the solution with the lowest total cost present value as the optimal solution:

[0074] The initial investment in equipment for Manufacturer 1 and Manufacturer 2 is RMB 8.14 million and RMB 9 million respectively. After discounting the electricity charges, the total costs are RMB 96.95 million and RMB 95.88 million respectively. Therefore, the equipment from Manufacturer 2 is recommended as the best.
