摘要:
针对电网的连锁跳闸问题，提出了基于危险度的分析方法。首先根据电网连锁跳闸事件的实际表现，结合连锁跳闸中距离Ⅲ段保护的动作行为，以电网当前运行状态下的节点注入功率与临界状态下的节点注入功率之间的欧式距离作为衡量连锁跳闸事件危险程度的指标。接着，建立了计算危险度指标的优化模型。最后，结合基本遗传算法，计算危险度指标，并在IEEE-39节点系统上进行了算例分析。结果表明，基于危险度分析电网连锁跳闸是合理的。
Abstract:
In view of the cascading tripping problem of the power grid, an analysis method based on the danger level was proposed. Firstly, according to the actual performance of cascading trips and the action of distance protection of Section III in the cascading trip, the Euclidean distance between the nodal injection power of the current operation state and that of the critical state was taken as an index for measuring the danger level of cascading trips. Secondly, an optimization modal for caculating the index was built. Finally, combined with the basic genetic algorithm, the index of the danger level was calculated and an example analysis was conducted on the IEEE39 node system. Results show that it is reasonable to analyze the cascading tripping of the power grid on the basis of the danger level.
