摘 要:针对现有电力系统机电暂态仿真软件中SVG固有模型难以适应工程应用的情况,以PSCAD/EMTDC中基于实际工程案例的SVG模型为参考,利用电力系统分析综合程序(PSASP)的用户自定义模型功能,开发具有易调试、易观察、可灵活调整的SVG自定义模型,并结合仿真算例,与PSCAD/EMTDC软件建立的SVG模型进行对比。结果表明,自定义的SVG模型动态响应与PSCAD/EMTDC软件仿真结果趋势基本一致,SVG自定义模型能满足实际工程的仿真需求。Since the inherent SVG model in the existing power system electromechanical transient simulation software is difficult to adapt to its engineering application, this paper firstly takes the SVG model as a reference, which is based on actual engineering cases in PSCAD/EMTDC. Then a self-defined SVG model has been developed by using the user-defined model function of PSASP software. This model is easy to debug and monitor, and it is also flexibly adjustable. This paper also compared the self-defined SVG model with the SVG model under PSCAD/EMTDC software, by simulating the same project. The results show that the dynamic response of the self-defined SVG model is basically the same as the simulation results of PSCAD/EMTDC software. Therefore, this self-defined SVG model can well meet the engineering simulation needs for the real applications.
