本文提出了一种计算三相变压器相坐标节点导纳矩阵的对称分量法，其中每个接线由三个单相单元或一个三相单元组成。该方法是基于组装成不同的三相连接的对称分量电路，它可以直接处理不对称的Transformer银行与不同的相位电气特性或缺相，接地阻抗。所提出的方法很容易占引用的各种时钟数在英国标准（BS）和国际电工委员会（IEC）标准的电力变压器，这提出了一个优势相比，经典的相位坐标的方法，需要定义一个不同的连接矩阵对应于每个Transformer矢量组。
This paper presents a symmetrical components approach for computing the phase-coordinates nodal admittance matrices of three-phase transformers, where each connection is comprised either of three single-phase units or one three-phase unit. The approach is based on assembling the symmetrical component circuits into the different three-phase connections; it can straightforwardly handle unsymmetrical transformer banks with different phase electrical characteristics or missing phases, and grounding impedances. The proposed approach easily accounts for the various clock numbers quoted in the British Standard (BS) and the International Electrotechnical Commission (IEC) Standard on power transformers; this presents an advantage as compared to classical phase-coordinates approaches that require defining a distinct connection matrix corresponding to each transformer vector group.
