Transformation design of 110kV substation in Xi'an petrochemical plant 1

Abstract:This paper mainly written for the reforming and design of the 110kV substation of Xi'an Petrochemical General Factory. First of all, According to the system and the route of the task book and the parameters of all the load, through the design of substation and the analysis of load data . We determined the main wiring form of 110kV and 10.5kV. On the basis to meet the national standard of design, the design as far as possible to consider the local actual situation. In this design, including the substation overall analysis and load analysis,main transformer selecting, Electrical main wiring, Electrical equipment selecting , The calculation of Short-circuit current and Lightning protection design. This design is pided into two parts, Design specification and Design calculation specification. Design specification include Transformer selection description, Electrical equipment selection instructions, Design of power distribution system, Lightning protection design. Design calculation specification include Transformer selection, calculation of short-circuit current, Electrical equipment selection and calibration. With electrical wiring diagram and other related drawings.
