电压静态稳定性分析及对策

THE ANALYSIS AND COUNTERMEASURE FOR VOLTACE STATIC STABILITY

基于电力系统ＰＱ节点可控性理论，提出了一种降阶的雅可比矩阵，并在单恒定功率负荷－∞系统上进行了论证，在多机系统上进行了计算，结果表明此模型是可靠的。最后通过对Ｗａｒｄ－Ｈａｌｅ６节点系统的计算，对减负荷点的选择进行了探讨。

The paper proposes a reduced Jacobi matrix based on the theory of the PQ node controllability.t is verified at a single constant power load-infinite system , the result shows that the model is reliable. At last, the author investigate the optimal load-shedding node through the calculation on the Ward-Hale 6-node system.
