| Abstract: | Based on the characteristic analysis of short-circuit impedance for adjustable tap transformers,the defects of the transformer model is pointed out,and the detailed correction method is proposed.Taking the East China Power Grid as an example,the bad influence that the defects may exert on power flow calculation and short-circuit current calculation is assessed,and the influence mechanism is analyzed.Suggestions on the simulation calculation in practice are put forward based on the assessment. |
