Abstract: The main electrical wiring of 220 kV substations has been designed. Based on the general power supply situation, load calculation, reactive power compensation capacity and other factors, this paper analyzed the specific form of the wiring, the selection of main transformer and gave the calculation of short-circuit current, electrical equipment and bus selection criteria. The results show that the design has high practicability in actual power transmission process.
Key words: substation; main wiring; load calculation; short-circuit current
