本文介绍了在实时数字电力系统仿真器中实现频变线路模型（FD-Line）。这样的发展的主要目标是描述一个通用的程序，将新的现实模型的电力系统组件在现代实时仿真器的基础上的电磁暂态程序（EMTP）。在这个过程中，首先，步骤，以获得时域解的微分方程，模拟电磁行为的多相传输线与频率相关的参数。之后，在Simulink环境中实现了FD-Line模型的算法解决方案，通过C语言编程的S函数，用于运行电磁暂态的离线仿真。该实现允许FD线路模型与电力系统模块集库的任何元素自由组装，并且还可以用于构建任何网络拓扑。在Simulink中构建电力网络的主要优势是可以通过商业eMEGAsim仿真器实时执行。最后通过仿真实例验证了FD-Line模型的准确性和实时性。
In this paper is described the implementation of the frequency-dependent line model (FD-Line) in a real-time digital power system simulator. The main goal with such development is to describe a general procedure to incorporate new realistic models of power system components in modern real-time simulators based on the Electromagnetic Transients Program (EMTP). In this procedure are described, firstly, the steps to obtain the time domain solution of the differential equations that models the electromagnetic behavior in multi-phase transmission lines with frequency dependent parameters. After, the algorithmic solution of the FD-Line model is implemented in Simulink environment, through an S-function programmed in C language, for running off-line simulations of electromagnetic transients. This implementation allows the free assembling of the FD Line model with any element of the Power System Blockset library and also, it can be used to build any network topology. The main advantage of having a power network built in Simulink is that can be executed in real-time by means of the commercial eMEGAsim simulator. Finally, several simulation cases are presented to validate the accuracy and the real-time performance of the FD-Line model.
