： 10/0.4kV choice of main transformer substation;
substation main electrical wiring design; short-circuit current calculation; load calculation;
reactive power compensation; electrical equipment selection. According to the main line
should be designed to meet the electrical reliability, flexibility, economy requirements, the
substation high voltage side of main power line connection using a single bus, single bus
low-voltage side of the main electrical connection in the form section; on the low side of the
load Statistics calculated using the required coefficient; in order to reduce reactive loss and
improve energy utilization, the design of reactive power compensation design, the power
factor from 0.69 to 0.9; short circuit short circuit current calculation, including the choice of
specific numerical calculation; and electrical equipment to choose from a selection at rated
current, according to the results of short-circuit current calculation method of verification....2
