Research And Design Of Capacity Expansion Project For Bailang 66KV Substation In Aershan City Of Xing'an City

Substation refers to the place where the voltage and current are transformed,the electric energy is received and distributed in the power system.The substation in the power plant is a boost substation,the function of which is to boost the power generated by the generator and feed it to the high-voltage power grid.In this paper,aiming at the research and in Xingan Aershan City,the Bailang66 kV substation in Xingan Aershan City is located in Bailang Town,Aershan City,Xing'an City,and is an important power supply in this area.Bailang 66 kV substation is designed according to unattended conventional substation.The experiental data were used to verify the proposed cross-sectional size model.Based on the basic requirements of the research and design of Bailang 66 kV substation capacity enhancement project in Xingan Aershan City,according to the relevant basic rules of power system on substation design,starting from the actual conditions of the project,A detailed analysis of the actual situation of Bailang 66 kV substation.According to the local natural situation and economic development of Bailang area,and the prediction of power load growth,and on the basis of detailed understanding of substation load characteristics,specific location coordinates and internal structure with substation designers,this paper analyzes the natural situation and economic development of Bailang area,and forecasts the increase of power load.Combined with the actual situation,this paper puts forward an economical,reasonable and easy to construct scheme design for Bailang Substation.This paper mainly studies the load characteristics of substation,the particularity of power supply line and the configuration of secondary protection system.on the basis of field investigation,data collection and modern power science theory,The design scheme of substation capacity enhancement project with high power supply reliability,safety and stability,economy and application is studied and designed.According to the research scheme to the field investigation of the project,master the most accurate field data,according to the current operation of Xingan power grid and long-term planning conditions,engineering design scope and design basis,put forward an overview of engineering design.By consulting the relevant literature and related theoretical calculation,the load characteristics of substation can be accurately located.By calculating the electronics,we could obtain the relevant parameters about electron,and the main wiring form are determined,and the primarypart of the power system design is completed.According to the relay protection mode of the system and the present situation of dispatching automation,the design scheme of the secondary system is determined.
