本文基于PSS/E电力系统仿真软件,采用Fortran语言对电力系统励磁系统进行了自定义建模。首先介绍了PSS/E用户自定义建模的基本原理及主要难点,其次对励磁系统中常见环节进行等价变换以方便选取状态变量;然后利用Fortran自定义了SEXS型和Vco Type 16型励磁系统;最后在WSCC 9节点测试系统上进行仿真验证,仿真结果验证了本文自定义模型的可行性和合理性。

In this paper,the basic principle and main difficulties of user-defined modeling have been introduced firstly.Secondly,with an appropriate equivalent transformation between ordinary links in excitation system,state variables can be extracted.And the excitation system of user-defined SEXS type and Vco Type16 are realized with FORTRAN language.The simulation of WSCC 9 bus system shows that the two types are reasonable.The user-defined modeling method proposed in this particle is also suitable for other electric elements,especially for the new control elements.
