Engineering Feasibility Research Of 220KV Power Transmission Of North Xinghua

With economic developing, social progressing, land and resources of transmission lines have been increasingly tensing. In the power grid construction, must vigorously promote the use of advanced and practical technology to improve power transmission and distribution capacity, conservation of land resources, reduce network losses, saving investment. In the power system, substations of transmission and distribution are the assembly points, responsible for transformation and adjustment of voltage, receiving and distributing power, control, load flow and other tasks. It consists of primary equipment and secondary equipment components. Project itself should meet the energy policy, energy consumption has played an active role. Transforming power project with investment of huge resources required a large amount of financial risk increases, and long payback period, the key to its success or failure depends on the correct decision or not. Therefore, to avoid investment risks, investment decisions must need scientific methods to strengthen and standardize the power transmission project feasibility study, and its scientific analysis and prediction. The feasibility study is to determine whether the project basis for investment decisions, the project cycle, an important and indispensable aspect of the project through the feasibility of the technical and economic feasibility of different technical and economic comparison building programs to make selection and judgement and decision-making process. Based on the Dongbao Town, on the northern part of the Xinghua City, which load power needs analysis, and considering the local economic development, natural and geographical conditions, and make power transmission engineering feasibility analysis. Emphasize construction necessity and urgency of the power transmission project. In this area, building one 220KV substation could meet the need of the new power's load on the north area of Xinghua City, to ensure the sufficient power supply for the economic development of this region, largely improving the power supply condition in this region. It could reduce the radius of other power supply and adjust the pressure of overloaded substation. In this paper, after field investigation, combined with the technical and economic comparison of the address and technology programs, analysis and calculation of the power system, which demonstrates the feasibility of the 220kV power transmission project. All of this is necessary for conducting the future project, to ensure that project decision-making more scientific, objective and rationality, conforms to the enterprise economic benefits as the center of investment principle.
