项目摘要

Visualization technique of dynamic phenomena and steady-state condition in large-scale power system has been studied in this research.1.P-delta map, V-dalta map, Q-delta map and Q-V-delta map are proposed and their 2D animations are developed, where P and Q are active and reactive power through transmission line respectively and V and delta are magnitude and phase angle of node voltage respectively.2.3D animations of unstable and poorly damped swing phenomena in large-scale power system are developed as shown bellow(1) animation with vertical pole, height of which represents phase angle or angle speed, and horizontal pipe representing transmission line, diameter, color or moving stripe of which represents active power flow(2) animation with balloon, diameter and vertical position of which represent stored energy and phase angle of generator respectively, and pipe between balloon and load node representing active power flow through transmission line(3) animation with vertical pole, height and diameter of which represent node and transmission line respectively and horizontal position of which represents phase angle(4) animation with disk, diameter and rotation of which show magnitude and phase angle of voltage respectively, and elastic strings representing synchronizing power.3.Some oscillatory modes of swing phenomena analized through FFT are represented as 3D animations to help us understand physical meanings of complicated power swing phenomena. As a result, it has been made clear that it becomes easy to understand intuitively where what kinds of oscillatory mode appear by looking at the above 3D animation.4.2D animation is developed to show how coherent generators behave during the period of oscillation in large-scale power system.5.3D animation are developed for voltage instability phenomena in small model system.

本研究对大规模电力系统动态现象和稳态工况的可视化技术进行了研究。1.提出了P-delta图、V-dalta图、Q-delta图和Q-V-delta图及其二维动画。等式，其中 P 和 Q 分别是通过传输线的有功功率和无功功率，V 和 delta 分别是节点电压的幅度和相位角。 2.3D 大型电力系统中不稳定和弱阻尼摆动现象的动画如图所示波纹管(1) 带有垂直杆的动画，其高度代表相角或角速度，水平管道代表传输线，其直径、颜色或移动条纹代表有功功率流(2) 带有气球、直径和垂直位置的动画分别代表发电机的存储能量和相位角，气球和负载节点之间的管道代表通过传输线的有功功率流(3) 动画，其中垂直极点，其高度和直径分别代表节点和传输线，其水平位置代表相角(4) 动画，带有圆盘、直径和旋转，显示其大小分别为电压和相位角，以及代表同步功率的弹力绳。3.通过FFT分析的一些摆动现象的振荡模式被表示为3D动画，以帮助我们理解复杂的功率摆动现象的物理意义。因此，很明显，通过查看上述 3D 动画，可以很容易直观地理解什么类型的振荡模式出现在哪里。开发 4.2D 动画是为了显示相干发生器在大范围振荡期间的行为。规模电力系统。针对小模型系统中的电压不稳定现象开发了5.3D动画。
