Technical And Economic Analysis Of The Feng Nan 500kV Substation Project

The basic energy industry, including power industry, is one of the most important part of national economy. The steady development of the power industry has the ability to provide strong energy to guarantee the development of social and socio-economic.At the mean time, the typically investe amount of power construction projects is huge. The power industry,which has a closed relationship with the community, is a capital-intensive and technology-intensive industry.Considering that the substation project needs a lot of money, complex technical issues and long cycle, it will help us to clear the technical feasibility and economic reasonableness of the investment projects after using the theory of technical and economic to analysis the substation project. On the one hand, the integrated economic benefits of investment in construction projects can be maximized. On the other hand, the technical and economic analysis of substation project can control the scale of investment, provide scientific direction for the project investment, and promote the health development of power industry.This paper mainly analyzes the technical and economic feasibility of the new construction engineering in Fengnan 500 k V substation.Firstly, the research background and significance were described in this paper.,and comprehensive threoy ofproject management were discusseed. Secondly, this paper introduces the general situation of the Fengnan 500 k V substation and the general situation of the surrounding power network, and analyzes the necessity of the new engineering of Fengnan substation.. Then this paper discussed the site of this new substation and some relevant technical problems which contain the electrical wiring, the twice electric, system communication and system protection. This paper also discussed the financial net present value, the payback period of investment and financial internal rate. The restult show that the investment of 500 k V substation construction has good profitability and it is acceptable. Finally, based on the above, the technical and economic analysis of the Fengnan 500 k V substation project is carried out, by using the analytic hierarchy process, the technical and economic effect of the technology is good, and the project is feasible..
