忻长110kV户外GIS变电站电气一次设计

Electrical Primary Design of Xinchang 110kV Outdoor GISSubstationAbstractDesign quality is the determining factor for the smooth construction,safe,economical,and stable operation of engineering construction projects,as well as the implementation ofthe principle of minimum cost management throughout their entire lifespan.The design of substations is guided by the principles of safety and reliability,advancedtechnology,economic flexibility,ease of maintenance and repair,and reasonable selection ofequipment and layout plans.Based on the comprehensive application of the implementationrules for substation design and construction,combined with practical situations,innovativedesign concepts,and improved design and deep design are carried out.A design schemewith advanced technology,safety and reliability,excellent indicators,and equal emphasis oneconomy has been proposed.On the basis of summarizing its development achievements,the main electrical wiringmode and selection of main electrical equipment in the substation were designed.When ashort circuit fault occurs,it can effectively damage the system,ensure the safety andstability of the substation during operation,and calculate the corresponding short circuitcurrent.Relevant standards should be followed in the selection of substation,transformermodel,and electrical main equipment.Finally,carry out lightning protection and groundingdesign.Finally,the feasibility of the design was verified technically.At the same time,summarize the design scheme and electrical equipment selectionKeywords:Substation design;Electrical main wiring;Equipment selection;
