Feasibility Study And Design Of Meifeng35kV Power Transmission Project

As an essential part of electric power system, power transmission project has adirect effect on the safe and reliable operation of the whole power supply system.Therefore, the scientific and rational design scheme of the power transmission projecthas extremely important application value and practical significance.According to the economic development of Haiyang and the actual demand ofYantai Meifeng Machinery Co., based on the Yantai grid12th five-year plan and the2030Vision and the12th five-year development plan of Haiyang grid, combined withthe relevant requirements of State Grid Corporation of power transmission projectfeasibility study depth of content (Trial), this paper fully analyses and demonstratesthe necessity of35kV power transmission project. Then we determine the reasonablescale of construction work and commissioning of years and finalize the program ofthe access system and the second order system. The route selection and theengineering vision are also clarified. At last, the investment estimation of the projectis provided in this paper.The paper begins with a detailed analysis of the current development of Haiyanggrid system. Based on the deep analysis and research on the typical design of35kVpower transmission project, the paper completed a35kV power transmissionengineering design scheme after making comparison from a variety of programs,including the load forecasting and site survey. The location of the substation, thescheme of access system, the construction scale of the substation and thecommunication program are described in details. Besides, the relevant equipments ofthe substation are selected and a scientific layout of the construction is provided.Meanwhile, the transmission line route selection, the steel tower and steel tower wireselection and the basis form of the establishment and so on are completed in the paper.According to the scale and engineering quantity of the project, investment estimationand investment analysis are done. With this, we can conclude the necessity of theconstruction, the technical feasibility and the reasonableness on the economy.At present, the preliminary design scheme of the project has won the provincialapproval of Shandong Electric Power Company, and the project has been into thedetailed design and construction phase. This paper fully anticipates and resolves manypractical problems of Meifeng35kV power transmission project, so it has practicalsignificance for the construction of the similar power transmission project in thefuture.
