以通用的同步电机派克方程为研究对象，对在EMTDC／Pscad中编制电机模型子程序及其与主程序接口问题开展研究。采用隐式梯形迭代算法对电机模型进行处理，利用Fortran语言完成电机子程序的编制。重点对仿真软件中电机模型的离散算法处理和模型的接口方式开展仿真验证，提出了采用不解耦的数值算法在EMTDC／Pscad电磁暂态计算软件中实现电机建模的方法。通过与软件自带模型库模型的比对，证明了建模方法的正确性及应用于多相同步电机仿真建模的可行性。

Taking the synchronous machine Park equation as research object; writing machine model subroutine and interfacing it with EMTDC, using trapezoidal iteration method to deal with synchronous machine equation in d-q coordinates system and programming the model subroutine in FORTRAN numerical machine model based on discrete algorithm, this paper presents an un-coupled math algorithm and interface method of synchronous machine model with EMTDC, and the interface processes to EMTDC electric network solution are specially deduced and tested via a simulation case..By comparing with the demos of a three-phase synchronous machine in the PSCAD master library, the validity and applicability suit for multi-phase synchronous machine model design are verified.
