摘要
通过对实际可调分接头变压器的短路阻抗特性分析,指出了变压器模型中存在的缺陷,并提出了具体的修正方法。以华东电网为例,评估了修正前可能给潮流计算和短路电流计算结果带来的影响,分析了其影响机理,据此,对工程实际中的仿真计算提出了建议。
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.
