基于PSASP的电力系统机辅分析软件的开发及其可视化实现

可视化技术可以将电力系统运行状态的大量信息以直观、简捷的方式显示给系统运行人员。电力系统综合分析程序(PSASP)以强大的计算仿真功能被广大研究人员所采用。以PSASP的计算功能为内核,开发了包含建模可视化、输出分析可视化的电力系统机辅分析软件(CAA)。本软件的仿真计算结果更符合分析人员的思维习惯,实现了基于轨迹分析法的暂态稳定可视化评估;同时具备元件模型参数自动循环调整的功能,可利用差分形式研究参数的轨迹灵敏度;可视化表现方式不仅具有三维显示,同时还可与MATLAB相链接实现多样化的表现方式。算例验证了各项功能的正确性和有效性,为电力系统的运行分析及根据实测轨迹调整参数提供有力的工具。

Development of a power system CAA software and its visualization based on PSASP

The vast amounts of information about the power system operation state can be present in an intuitive and quick manner by the visualization technology. The power system analysis software package (PSASP) is adopted by the operators for the powerful calculation function. A computer assistant analysis (CAA) software is developed based on the kernel calculating function of the PASAP, which incncludes the visual modelling, visual output analysis.The calculation and simulation output are coincident with the researchers' thinking habits. The transient stability evaluation is realized by the trajectory analysis method. At the same time it has the function of modifying the components model and their parameter automatic circulation, then the trajectory sensitivity can be got by the difference form. The test is shown that every function is correct and effective. It is a powerful tool for power system analysis and correcting parameters according the measured trajectory.
