New Wulan-aodu 66kV Power Transmission And Transformation Engineering Design

With the rapid economic development of modern society,the power market demand is increasing day by day.As the basic unit of the whole power system,substation plays an important role.How to build a more reasonable structure,more intelligent function of the substation,the current electrical field has become a hot topic of research.In this paper,based on the situation of xingan ke youqian banner area,from a macro perspective,the new ulan aodu 66 kV power transmission and transformation project is discussed.Based on the principle of accelerating substation construction and intelligent operation,the design of this project is completed.The new ulanaodu 66 kV power transmission and transformation project is designed in accordance with the requirements of power grid planning and system design,in view of the load demand in the western region of keyouqian banner.Only by putting the project into construction as soon as possible,can the contradiction between power supply and electricity be effectively solved.The main work and results of this paper are as follows:(1)According to the actual situation of regional power grid,a new substation construction mode is carried out based on the concept of high efficiency,low energy consumption and environmental protection.Through load analysis and prediction,the primary equipment of the newly built substation is selected,the system access scheme is proposed,and the power flow calculation is verified.The circuit model,reactive power compensation device and neutral grounding method are analyzed.Complete equipment selection and electrical wiring planning and layout.(2)Put forward the construction plan for the relay protection system,dispatching automation system and communication system of the newly built substation,so as to promote the sharing of communication information,optimize the collection method and optimize the project.In order to promote the implementation of the new power transmission and transformation project,the access system scheme and the construction of new stations are introduced.The transformation of access station was studied and analyzed in detail,and the planning was completed by making full use of the methods of environmental protection and energy saving.Through calculation comparison and data demonstration of different design schemes,the optimal scheme was finally selected.This paper completes the overall design of power transmission and transformationproject,which is practical,economical,stable and intelligent.The planning and construction of the station can strengthen the regional power grid structure,greatly improve the reliability of power supply,and provide a prerequisite for local economic development.
