Comprehensive Evaluation Of Wanli’s 220KV Power Transformer Engineering Project

Under the current system, the grid company is responsible for the construction and maintenance of electricity transport and transformer engineering seting up. But now in the one hand, transmission and distribution sectors are the state monopolies, but they have to accept the supervision of government departments. On the other hand in order to maintain long-term health and sustainable development, the power companies as utilities, in addition to the power grid construction investment projects should consider its economy, but also need in some respects to social benefits at the expense of some of the economic benefits. Therefore, comprehensive evaluation for grid construction projects on the grid company’s future sustainable development is great significance.Taking the construction of Wanli’s 220KV power transformer engineering project as a base, this paper makes a study on comprehensive benefit evaluation of Wanli’s 220KV power transformer engineering project. First of all, introduced the background and significance of the research, analysis on the domestic and foreign research situation of comprehensive evaluation of the project’s overall summary and system, in addition, summarizes the basic theory of comprehensive evaluation of economic benefit of the power transmission project; secondly, on the basis of the theory, the development status of power transmission project Erdos area, through the need for power the development practice of our country’s point of view, analyzes the necessity of Wanli 220KV power transmission project construction; thirdly, according to the characteristics of the scale and construction of the power transmission project construction, and construction in construction process, the project effect and economic benefit, social benefit, the project’s impact on the environment and sustainable development, etc. the project of comprehensive evaluation index system; finally, using AHP and fuzzy comprehensive evaluation method of the two methods for comprehensive benefit evaluation of the Manley 220KV power transmission project, and the results of comprehensive evaluation of the operation are analyzed, according to the comprehensive evaluation of the results of the project put forward effective suggestions and countermeasures.
