Through tothesubstation design inpower supply system ,itcan deepen understanding ofthe substation inpower system and the role ofthe power system equipment function and selection principles. This design given bythe factory workshop substation load tables for load calculation,and then follow putational load oftransformer substation main transformer and the workshop are selected models .According tocalculation oftransmission line cross-sectional area selects models ofoverhead the wiring diagram ofthe power supply then the short-circuit point set for the calculation of short-circuit current,and select different variable pressure side ofthe electrical equipment and last,set relay protection device and setting calculation. This design isthe main basis ofthe provisions of the relevant design manual, through calculation and analysis, reasonable selection ofall kinds ofequipment. Key words load calculation short-circuit calculation electrical equipment choice relay protection 本科毕业设计说明书( 论文) 第Ⅰ页共Ⅰ页目次 1引言...................................................................................................................................
