| The establishment of this topic is based on the urgent need to solve the problems in the Xing'an League power grid.The problem is: There is a banner county called the Horqin Right Wing Front Banner at a distance of ten kilometers to the west of Ulanhot City.The former Qiqi Government has established an industrial park in the Keqianqian Banner area through preliminary planning and design and investment.It is expected that the load will be large.The current grid structure is not enough to bring out these loads.Although this industrial park is only planning,but in line with the economic development,the concept of the grid first,our grid company decided to set up an economic park at the same time,supporting the strengthening of the grid structure.After the completion of the 220 kV substation of Xing'an Mengkeqianqian Banner,it will mainly meet the industrial power demand of the Kezhenqian Banner industrial processing concentration area,and at the same time take into account the load development needs of Dabagou Town where the government of Keyouqian Banner is located and other parts of western Ulanhot City.Right front flag and Xinganmeng's economic growth provide reliable power support.Satisfying the increasing load demand of the Keyouqianqi Banner will ensure the sustainable development of the Xinganmeng economy.In this paper,the overall system design of the power transmission and transformation project is firstly designed.The primary scheme of the power system,the relay protection scheme,the automation scheme and the communication system scheme are designed.Then the station site of the substation is inspected and determined.The two most suitable sites have been compared in various ways,and the final site has been selected,and the secondary side of the primary side of the 220 kV substation of Keyouqian Banner has been designed;then the line of the substation has been designed and passed.Field survey,determine the path plan,according to the local meteorological conditions,to determine the type of wire and ground model,followed by insulator design,lightning protection and grounding design,and finally design of the transmission line of the tower design,iron tower foundation design.Through the analysis of the technical and economical aspects of the power transmission project,it is demonstrated that the construction of the power transmission project is necessary and feasible. |
