具有非标准变比变压器的参数计算

文章论述了电网分析计算中变压器参数的计算方法。变压器的等值电路在一般计算程序中的三种表示法，同一台变压器三种等值电路中需给出不同的参数。按常规方法计算的同一参数提供给不同等值电路的计算程序，有时会带来一定的误差，文章分析了产生误差的同时，可供计算分析人员参考。

PARAMETER COMPUTATION OF TRANSFORMER WITH NON-STANDARD VOLTAGE RATIO

There are three expression modes of equivalent circuit of transformer in common computation programs. Distinct parameters are needed in those three equivalent circuits describing an identical transformer in order to obtain correct results. Some errors will occur if the data from the common computation method described in textbooks are input into the program with different equivalent circuit. The reason which brings about the errors is analyzed in this paper by given examples.
