文章探讨了电力系统实际工作中变压器的并列判别问题。通过变压器并列运行分析，提出变压器并列运行的理论依据。根据一般的计算两双绕组变压器并列运行变比差、阻抗电压差公式，推导出三绕组与三绕组、三绕组与两绕组并列运行的变比差、阻抗电压差计算公式以及产生的环流。解决针对不同型号、不同绕组变压器并列运行计算分析难的问题，根据并列运行约束条件以及相关计算公式，用 C#语言设计开发了一款变压器并列运行程序计算器，最终打包形成软件，实现变压器并列运行自动计算分析功能。此变压器并列运行程序计算器最终能够实现变压器并列运行由手算转变为软件计算的目标，既提高了工作效率又保证了准确性，也实现了变压器并列运行计算分析的标准化。

The paper discusses transformer paralleling operation problem in the practical work of power system. Through the analysis of transformer paralleling operation,the paper puts forward its theoretical basis.According to the commonly used calculating formula of ratio difference and impedance voltage difference of double winding transformer paral-leling operation,the calculating formula of ratio difference and impedance voltage difference of paralleling operation of three-winding and three-winding or three-winding and double winding transformer is derived and the corresponding circulat-ing current is presented.To clear up difficulties in analyzing paralleling operation of different kinds of transformers with different windings,based on the constraint conditions of paralleling operation and related calculating formula,a kind of cal-culator program for transformer paralleling operation is developed by C# language.It is packaged as software which reali-zes functions of automatic calculation and analysis of transformer paralleling operation.It will improve the work efficiency and ensure accuracy.At the same time,it also realizes the standardization of calculation and analysis of transformer paralle-ling operation.
