| 中文摘要 | 可信域是电力系统暂态稳定域近似边界的有效范围,位于稳定域边界上的特征不变流形是确定可信域的重要工具。计算特征不变流形与近似边界的偏差是确定可信域的关键步骤。该文给出一种实用的可信域计算方法。该方法定义特征不变流形上一点和穿过该点沿某一坐标方向与近似边界交点间的距离为偏差。通过WSCC4机11节点系统和IEEE10机39节点系统仿真,结果表明该偏差与严格意义下的偏差具有一致性,可用于提高电力系统暂态稳定近似边界可信域计算的速度。; The credible region is the valid range on the approximate stability boundary of power systems. The errors of the points on the characteristic invariant manifolds for the approximate boundary are used to estimate the credible region. This paper presents a practical algorithm to calculate the credible region with the error defined as the distance between a point on the characteristic invariant manifold and its projection point on the approximate boundary along a specified coordinate direction. Simulations with the WSCC 4-machine and the IEEE 10-machine systems show that the error distribution calculated by the algorithm is quite similar to more accurate results with a much shorter calculation time.; 国家“九七三”重点基础研究基金项目(2004CB217904) |
