About Xing'an Power Grid 220kV Front Banner Intelligent Substation Preliminary Design Of The New Project

Since the 21 st century,the economic globalization has gradually deepened,emerging technologies such as big data,artificial intelligence and the Internet of Things have gradually appeared,and the level of productivity has continued to increase.With the prosperity of the core area of the urban area of Ulanhot,Xing'an League,Kerqin Right-wing Qianqi has gradually developed Corresponding industrial and commercial areas and core residential areas,many urban residents and enterprises,institutions,shops,hospitals,schools,factories,etc.take Kerqin Youyiqianqi area as the best choice for relocation,large shopping malls in Kerqin Youyiqianqi area,There are more and more high-end communities,residents' income is gradually increasing,and the quality of life has improved significantly.In addition,the demand for stable and reliable power supply in Horqin Youyi Qianqi area is increasing.In addition,in order to alleviate the pressure of long-distance transmission between 220 kV substations in the Xing'an League region and strengthen the 220 kV backbone grid structure,the related work of designing a new project for the 220 kV Qianqi smart substation in Keyouqianqi of Xing'an Power Grid was carried out,which is designed for Korqin The right-wing Qianqi area provides more stable,safe and reliable power supply.At the beginning of this thesis,the significance and background of the research work on the construction of the new 220 kV pre-substation project are elaborated in detail,the research direction and core content of this paper are put forward,and the theoretical basis for the research and design of the new construction of 220 kV Qianqi substation is introduced in detail.Next,this paper analyzes the power demand,power supply load and current power supply status of the Kerqin Right-wing Qianqi area and Xing'an League in an objective manner,and elaborates the new construction of 220 kV Qianqi Substation from the perspective of importance and necessity.Demonstrated the systematic scheme of this study.Finally,the paper analyzes and calculates the parameters of relay protection design,reactive power compensation,total capacity and short circuit current amplitude,and selects the primary and secondary equipment reasonably and arranges the concrete contents of power system design reasonably.
