Study And Design Of Main Transformer Expansion Project For Dashizhai 66kV Substation Right Front Banner Of Xingan

With the continuous development and progress of production and economic,right wing front banner has gradually become the focus of the docking Hinggan League core area residential areas,many urban residents living more and more to the right wing front banner region,more and more high-grade village built in the right wing front banner region,improve people’s living standard,the requirement to the quality of life increases,at the same time,the requirement of power supply reliability and stability of power system will gradually increase.In this context and in need,the design work of the expansion project of the main substation of dashizhai 66 kV substation in keyouqian banner of xingan power grid was carried out to further improve the reliability,safety and stability of the power supply system.In this paper,the background and significance of the research and design of the expansion project of the main substation of dashizhai 66 kV substation are firstly elaborated,and the theoretical basis of the design and research as well as the main research content of this paper are clarified.By analyzing the status quo,power load and demand of the power system of Hinggan League and keyouqian banner,the necessity and importance of expanding the 66 kV substation in dashizhai are pointed out,and the system scheme is demonstrated.Through the calculation and analysis of the circuit current and capacity,reactive power compensation,relay protection design and other related indicators,the reasonable intelligent configuration and arrangement of the primary design and secondary design of the power system are carried out.
