The main electrical wiring of 220 kV substations has been designed. Based on the general power supply situation, load calcula-tion, reactive power compensation capacity and other factors, this paper analyzed the speciifc form of the wiring, the selection of main trans-former 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.
