【Abstract】 This paper attempts to calculate AC and DC component of short-circuit current in Shanghai Grid by means of PSS/E BKDY short-circuit current calculation module.DC and AC component calculation are checked with the results of transient simulation by use of PSS/E and EMTP power system analysis software respectively.The calculation of decaying short-circuit current AC and DC component with PSS/E BKDY module is verified to be accurate,convenient and therefore quite promising for engineering application.更多还原
