摘要
基于电力系统实时数字仿真系统RTDS提供的自定义建模环境CBuilder,本文提出了电力系统元件的自定义模型设计方法,开发了C语言描述的算法、可视化的图形外观、组件化的功能的自定义元件模型,通过编译和封装,生成与RTDS自带模型相同执行效率的动态链接库。本文以IEEE型EXST1静止励磁系统为例建立起自定义模型,并通过搭建特定的电网场景对自定义元件和RTDS自带的模型分别进行闭环测试,测试结果表明系统在初始化过程、机端电压参考值阶跃过程、系统在大扰动情况等条件下两者外特性基本一致,验证了本文方法的正确性。
Based on the user define modeling environment CBuilder that power system real-time digital simulation system RTDS provides, this paper puts forward the method to design the user defined component. This paper develops the user defined component model which has the algorithm described by C language, visual graphics appearance, and the componential function, through the compilation and packaging, it generates the dynamic link library which has the same efficiency in the implementation of the own model of RTDS. This paper takes the IEEE type EXST1 static excitation system for example to build the User Define Component, and builds some specific grid scenes to test the user define component and the original component respectively. By comparison, the test results show that the external characteristics of the user define component and the original component are basically the same in the system initialization process, the terminal voltage reference value step process and in the conditions of the large disturbance, it verified the correctness of use defined control component based on CBuilder.
