摘要(Abstract)：
变压器模型是潮流计算程序中的重要模型之一,为保证潮流计算的精度,必须正确填写变压器的模型参数。从变压器物理模型出发,分析了BPA及PSS/E潮流计算程序的变压器计算模型,说明了计算模型如何自动适应变压器分接头的调整,指明了BPA及PSS/E变压器模型参数的正确填法,并对误填参数可能带来的潮流误差进行了评估。最后,用两个算例对结论进行了验证。
Transformer is one of the basic elements of electric power system,it's model parameters must be input correctly to power system analysis programs.This paper analyses the transformer models of PSS/E and BPA,illustrates how these models can adapt to the transformer's tap_changing automatically,demonˉstrates how to input model parameters correctly.Possible power flow error was estimated if imprecise data was given to the analysis programs.The authors evify their conclusions by two examples.
