Research On Shanxi Linfen220kV Quwo Smart Substation Project Post Evaluation

Power grid construction projects for the allocation of resources to protect national economic and social development, promote industrial restructuring, optimization has a very important role, and post-project evaluation grid project is testing whether the realization of the goals and benefits of pre-construction effects of the important means and links. Thus, from decision-making, technology, management, economic, and environmental protection point of view of the necessity, reasonableness,standard, advanced, economical power grid construction project analysis and evaluation, an important reference for decision-making and practical significance. Therefore, the smart substation project can be evaluated as the smart grid substation construction to provide guidance and reference, and establish evaluation index system for the smart substation project summary smart substation project experience and attention and guidance intelligent substation construction or renovation projects. It has a very important significance in the new environment for studying the problem.Smart grid concludes substation, transmission, distribution and delivery of an important part of building a strong smart grid focal point and end point, directly to customers, the community perception and experience is strong and smart grid construction achievements of the main ways. Smart substation is an important carrier power distribution, power quality related to smart grid and smart promotion. In Twelve-Five" period, smart grid construction investment will remain a large scale, and as one of the key national infrastructure. In this paper, Shanxi Linfen220kV Quwo smart substation project post evaluation is studied as an example, First, this paper introduces the intelligent substation engineering and project post-evaluation theory, Then introduces Quwo smart substation construction projects, concluding construction projects, environmental impact and sustainable development, and also gives the corresponding qualitative evaluation results. Finally, post evaluation of Quwo smart substation project has been studied from the implementation process, environmental impact and sustainable development three aspects, it can be a good combination of subjective and objective analysis of AHP method for determining the weight of each index evaluation, and at last some recommendations are given.
