静态电压稳定域的三维可视化技术

近年来对静态电压稳定域的研究表明其边界可在较大范围内以超平面的形式近似拟合,在三维空间中体现为一个空间平面,该结论降低了实现静态电压稳定域可视化的难度.文章利用上述研究成果依据同一断面上不同线路的电压稳定严重程度对其进行排序,以OpenGL为图形开发工具开发了静态电压稳定域的三维可视化系统.该系统已在河南电网投入使用,可帮助调度人员在线监视与评估不同运行工况和不同负荷增长方式下的电网电压稳定裕度.

VISUALIZATION TECHNIQUE OF STATIC VOLTAGE STABILITY REGION IN THREE-DIMENSIONAL SPACE

In recent years the achievement of the research on static voltage stability region shows that its boundary can be approximately fitted by hyperplanes in a larger range and in a three-dimensional space the intersections of the boundary appear as a plane. This achievement reduced the difficulty to implement the visualization of static voltage stability region. Using above-mentioned achievement the authors collate the voltage stability of different transmission lines at same cross-section according to their orders of severity. Using OpenGL as the development tool of graphics, a three-dimensional visual system of static voltage stability region is developed. This visual system is applied in Henan provincial power network and can help the dispatchers on-line monitoring and evaluating of the voltage stability margins of Henan power network under different operating conditions and different load increasing modes.
