Embodiment Construction

[0051] The post-evaluation method of a power transmission project based on the whole life cycle theory of the present invention will be further described below using the drawings and embodiments.

[0052] refer to figure 1 , a kind of post-evaluation method of power transmission engineering project based on the whole life cycle theory of the present invention, it comprises the following steps:

[0053] 1) Calculation of life cycle cost: life cycle cost includes investment cost and maintenance operation cost. The investment cost refers to the investment cost of purchasing equipment; maintenance operation cost refers to operation cost, maintenance cost, failure cost and decommissioning Disposal cost, the calculation formula of the whole life cycle cost is:

[0054] LCC=IC+OC+MC+FC+DC (1)

[0055] In the formula, LCC is the life cycle cost, IC is the investment cost, OC is the operation cost, MC is the repair and maintenance cost, FC is the failure cost, and DC is the decommiss...

Abstract

The invention relates to the technical field of wind power transmission, in particular to a full life cycle theory-based power transmission engineering project post-evaluation method. The method is characterized by comprising the steps of considering costs and benefits of a project by adopting a full life cycle theory, and analyzing total cost and benefit obtained in a full life period of an energy storage system; then, analyzing the costs and benefits of the project to find out main cost and benefit types, and calculating the main cost and benefit types; and finally, subtracting the project costs from the project benefits to obtain the total benefit of the project in the full life cycle, and analyzing benefits obtained by different energy storage systems. The full life cycle-based evaluation theory verifies that the effects of reducing a blockage wind abandoning amount and improving the benefits in the power transmission engineering project are remarkable. The specific method has theadvantages of scientificity and reasonability, high applicability, high accuracy, good effect and the like.

Description

technical field [0001] The invention relates to the technical field of wind power transmission, in particular to a method for post-evaluation of power transmission projects based on the whole life cycle theory. Background technique [0002] Today, my country's economic level is in a period of rapid development, more and more projects are launched, many enterprises are established and people's living standards are improved, followed by the increase in the use of various electrical equipment. These changes All lead to a substantial increase in power consumption. The production electricity consumption of various industries and the electricity consumption load of residents are growing rapidly and continuously, making the weak links of the existing transmission line structure gradually appear, and it is urgent to transform or build new transmission channels. In order to ensure the improvement of project investment benefits and fully understand the difference between the actual si...
