Design Of Construction Plan Of 35kV Zimulin Power Transmission Project

According to the economic development of Xinglong County, Chengde City, and the actual demand for electricity in Xinglong power grid, "Twelfth Five Year Plan" as the foundation, by the Chengde power supply company, Xinglong power supply branch carries out the design scheme of 35 kV power transmission project construction of Zimulin in work.With a detailed analysis of the current situation of Xinglong County power grid and load and power consumption trends,through field survey and load forecasting, the necessity of Zimulin 35 kV power transmission project construction has been fully demonstrated that Zimulin 35 kV power transmission project in Xinglong county meet the rapid growth of Zimulin load demand, further optimize the grid structure of the region, at the same time, improve the voltage quality and power supply reliability. Therefor, it is very urgent and necessary.The second chapter made the scheme of access system and substation, line and communication design, determine the reasonable scale of construction projects. according to the scale of the project and the project construction, the project investment is estimated and analyzed.The third chapter is based on the "design" the national grid, the conventional substation and substation project has carried on the contrast analysis and the design of substation 35 kV power transmission project of Zimulin has partly completed. the substation site selection, choice and design of substation, substation installation form of geographical conditions, protection configuration, electrical layout design, and the relevant equipment selection have also been completed.In the fourth chapter, the field measurement of 35 kV transmission line corridor, the path selection of 35 kV line, the meteorological conditions of conductor and ground wire, insulation type design, configuration and the basis of the tower have been determined, the design of power transmission line project in Zimulin 35 kV power transmission project has been completedIn the fifth chapter, Xinglong County Power Company Dispatching Communication and on the basis of the status quo, sets up the system scheme is feasible for Zimulin compared with conventional 35 kV substation, substation automation system, selected the scheme of substation, the function of substation automation are described.At present, Chengde Power Supply Company has approved the design of the project and the construction engineering design has now began. The construction scheme of Zimulin 35 kV power transmission project based on the code solve many practical problems.The experience has practical significance to the construction of similar engineering.
