摘　　要：用PSS/E BKDY短路电流计算模块对上海电网短路电流的周期分量和直流分量进行了计算,用PSS/E机电暂态仿真结果对周期分量计算的准确性进行了校核,用EMTP电磁暂态仿真结果对非周期分量计算的准确性进行了校核。结果表明PSS/E BKDY模块能够较准确地计算短路电流周期分量衰减和直流分量衰减,其兼有应用简便性而有很好的工程应用前景。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.
