摘要
目前普遍采用的三角形连接绕组变压器的三相数学模型，可以导致电力系统三相基波与谐波节点的导纳矩阵奇异性，从而不能得到准确的基波与谐波潮流的计算结果。本文提出了一种改进的变压器模型可以避免出现以上缺点，且通过算例证明此模型是可行有效的。
The currently used threephase mathematical models of transformers with deltaconnected windings may lead to admittance matrices singularity at the threephase fundamental and harmonic nodes of power systems, which may result in incorrect ourcomes or inability to carry out threephase f undamental and/or harmonic load flow solutions. A modified model was presented i n this paper to keep the admittance matrices away from singularity. Examples hav e proved the correctness and efficiency of the proposed model.
