| 摘 要： | 系统运行过程中,以消除运行约束越限为目标的校正控制策略可能导致系统的静态电压稳定裕度不满足要求。提出一种直接消除系统运行约束越限,间接提高静态电压稳定裕度的校正控制算法。该方法首先消除系统运行约束越限现象,然后通过潮流方程的切向量识别系统的薄弱节点,并利用电压幅值优化来间接地提高系统的静态电压稳定裕度。IEEE24节点和我国西北682节点系统的仿真算例表明,方法简单有效,计算速度快。

| Abstract: | Voltage security might worsen when alleviating operation constraint violation. A methodology for corrective control to alleviate operation constraint violation was presented while maintaining static voltage stability margin. Firstly, operation constraint violations were relieved without considering static voltage stability margin. Secondly, weak buses were provided by tangent vector and voltage magnitudes at weak buses were maximized to increase static voltage stability margin indirectly. Results of IEEE 24-bus system and a real 682 bus system show that the methodology is simple and efficient. |
