本指南包含在直轴和交轴等效电路中对同步电机建模的说明，以及从稳定性研究的角度考虑的基本瞬态和亚瞬态电抗/时间常数模型。它讨论了在使用各种模型时所做的假设，并介绍了发电机/系统接口所涉及的基本方程和概念。讨论了在网络研究中，无论是在初始化过程中，还是在大扰动或小扰动稳定性分析过程中，发电机饱和的处理方式。确定了提高磁场和励磁系统量精度的方法，并给出了将磁场参数从一个基座传递到另一个基座的转换系数，以便正确地进行发电机/励磁系统接口建模。包括参数确定以及从等效电路到工作阻抗或从等效电路到工作阻抗的转换。通过现场测试或有限元分析获得这些参数的数据分析方法- 用大量的发生器和测试数据解释和说明了元素计算。然而，本指南参考了安排此类测试的适用标准（如IEEE Std 115）或合同规范。此外，本指南并不试图为非标准或非典型情况下的机器表示推荐具体程序，如发电机跳闸和超速运行，或谐波或不平衡运行模型。

This guide contains instructions for modeling synchronous machines in direct- and quadrature-axis equivalent circuits, along with the basic transient and subtransient reactance/time-constants model in view of stability studies. It discusses assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. The manner in which generator saturation is treated in network studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Approaches for improving the accuracy of field and excitation system quantities are identified and conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Parameter determination and translation from equivalent-circuits to operational impedances or vice-versa is covered. Data analysis methods for obtaining these parameters using measurements from field tests or finite-element computations are explained and illustrated with a wide range of generator and test data. However, this guide refers to applicable standards (such as IEEE Std 115) or contract specification for scheduling such tests. Also, this guide does not attempt to recommend specific procedures for machine representation in non-standard or atypical cases such as generator tripping and overspeed operation or models for harmonics or unbalanced operation.
