The Project Feasibility Study Of Qitaihe City Huancheng110KV Substation Construction

Power project has the features of large amount of investment, long project cycle, andmany uncertainties. The key to its success depends on the correctly decision-making, anddecision making is based on the feasibility study of scientific analysis and prediction. So thefeasibility evaluation of the power project is very necessary and important. This paper, basedon Technology Economics, Project Management and Fuzzy Matter. Element Theory,analysed feasibil its studies of Qitaihe city Huancheng110Kv substation expansion project.In research methods, this article first separately from thetechnical, economic and socialbenefits in three areas of Qitaihe Grass Temple110Kv substation expansion projectfeasibility evaluation of a single factor. Treatment at the weights on, this article usessubjective weights and objective weights of the combination model.110Kv substation electrical system in urban town is widely used, there is more higherpractical and representative, so this topic research can be a basic understanding of our townof110Kv substation system composition and structure and construction ideas. This design,firstly, according to the city’s power supply and can be achieved in the actual situation ofelectrical load, the original data to provide load is analyzed, and USES of electricity loadcoefficient method to determine the calculation, the main transformer substation step-downfor capacity, the quantity and the wiring scheme worked. In considering the city planningand development in the future, according to type110Kv substation,miniaturization, low cost,safety and reliability, and advanced technology, the principle of the substation constructionaccording to the general layout design, consider saving miniaturization, covers an area ofelectrical layout, reasonable, concise and easy, occupy farmland less maintenance equipment.Second, considering the fault of the serious influence on system, analysis and calculation,and according to the short-circuit current high-voltage electrical current circuit for mainequipment and take-off equipment rationally choose. Again, the secondary circuit forsubstation and relay protection system, lightning protection and grounding system is also described in the system design, and proposes the design and construction of110Kvsubstation, The results show that the project is feasible．...
