Design Of Lianyungang Xing Chen 110kV Standard Assembly Type Intelligent Substation

With the promotion of the national grid proposed "standardized design,industrial production,assembly-type building",the construction of new substation concept of smart substation standard assembly came into being.Combined with the actual situation of Lianyungang regional power grid,in practical engineering background,for standard fabricated 110 k V substation intelligent design,the article is divided into the following sections:First,according to the status of Lianyungang regional power grid,to det ermine the scale of construction 110 k V substation Xing Chen,and then the system short-circuit current calculations to determine the portion of the main wiring electrical substation and key electrical parameters,lay the foundation for intelligent substation design.Based on electrical calculation results,this paper proposes a smart substation electrical system design.Respectively,from a smart device solutions,mainly electrical equipment selection,general layout and electrical distribution equipment type and other aspects of the 110 k V electrical substation Xing Chen intelligent primary system design.It should be noted that the substation building structures are used in factory processing,assembly structure with hanging site installation,greatly shorten the construction period.Subsequently,on the basis of a system of electrical solutions,the paper proposes an intelligent substation secondary electrical system design.Respectively,from the establishment of integrated substation automation system,component protection and automatic devices,intelligent control systems and auxiliary equipment group secondary cabinets and layout and other aspects of the 110 k V electrical substation secondary Xing Chen intelligent system design.Finally,through the engineering design stage construction of the prefabricated cabin technology application to achieve a compact arrangement of centralized secondary equipment,through the use of prefabricated cable,secondary equipment interfaces were standardized design,to achieve the second device "plug and play" spot reduce secondary wiring workload and improve the quality of the construction process of the cable,easy on-site commissioning,thereby further shorten the construction period.
