| 摘 要： | 提出一个辨识同步电机数学模型结构的新方法。利用奇异值分解（ＳｉｎｇｕｌａｒＶａｌｕｅＤｅｃｏｍｐｏｓｉｔｉｏｎ，即ＳＶＤ）理论，提出一个判据，据此检查从电机实际运行过程中测得的输入输出数据矩阵的奇异值，确定电机电路模型中的等效阻尼支路的数目。仿真计算和电机实际测算结果表明本方法具有好的准确性和实用性。

| Abstract: | A method of model structure identification for synchronous machines is developed, which uses the singular value decomposition (SVD) theory and presents a criterion for determining the number of equivalent damper circuits of synchronous machines directly from the input/output data of the machines under operation conditions. The results of simulations and real measurements show the effectiveness of the method. |
