| 中文摘要 | 提出一种新的紧急切负荷算法,以确保校正控制的安全性同时兼顾经济性。算法由恢复潮流方程可解性算法和满足电压稳定裕度算法两部分组合而成。前者利用电压稳定域边界的切平面方程辨识电压弱节点集,进而将该集的节点负荷量作为优化变量,并综合考虑切负荷量最小、有利于系统暂态稳定性提高和计算速度快等三项目标, 提出了逐次优化算法以恢复潮流方程的可解性；后者利用故障后电压稳定域边界的切平面方程,调整可控参数变量以达到最小电压稳定裕度的要求。IEEE-39节点系统的算例证明了该算法的有效性。; A novel emergency load shedding algorithm is presented to assure security of correct control taking account its economy,which is consisted of two stages.The first stage is to restore solvability of power flow equation and the second stage is to achieve requested load margin of voltage stability.Voltage weak node set is decided by tangent plane equation of voltage stability region's boundary.Successive optimization algorithm is presented to restore solvability of power flow equation,whose objective are minimum load shedding,beneficial to transient stability and having calculation speediness with load of voltage weak node set as optimal variables.Controllable variables are adjusted to achieve requested load margin of voltage stability according to tangent plane equation of voltage stability region's boundary of post fault.The algorithm has been validated by simulation of IEEE-39 system. |
