摘　　要：为了探寻由于数据问题给计算结果带来的误差,本文以襄阳电网为例,将110kV线路、变电站以及10kV配电网络布在襄阳电网数据包中,并且采用将整个10kV站配电网络阻抗等效的方法来进行建模,通过襄阳电网算例计算对比分析,表明考虑110kV以及10kV网络数据对于220kV站短路电流计算有影响,但是影响程度基本维持在5%以内,因此目前PSASP中220kV层面的网络数据可以用于计算短路电流。To research the error caused by the data of line and transformer below 110 kV in Power System Analysis Software Package(PSASP),this article takes the Xiangyang power grid as example.The data of line and transformer of 110 kV and 10 kV is included in the calculating package.The distribution network of 10 kV is adopted the method of equivalent impedance to establish the model.Through the calculating results of Xiangyang grid,it is proved that 110 kV and 10 kV data will affect the 220 kV short circuit current calculating results,but the influence is limited in 5%.So the 220 kV data in the package can meet the need of short circuit current calculating.
