基于“互联网+大数据”的危控区可视化管理思路分享

随着电力系统复杂性的增加、极端自然灾害的频发以及社会对电能依赖程度的增长,停电风险也越来越大。台风、雷电、覆冰等极端自然灾害在短时间内会造成电网的多个设备故障,加上潮流的转移、保护装置拒/误动的推波助澜,进一步加剧相继开断,甚至造成大面积停电。此外,因设备规划、布点限制,部分设备运行环境较差,受到洪涝灾害、冰冻灾害、地质灾害、树线矛盾等影响,将会导致电力设备直接或者间接受到影响和破坏。本文主要从“互联网+大数据”的危控区可视化管理进行研究分析。

Study on dangerous collision area of ships out of control in Sutong Bridge area

Motion state of ship out of control in bridge area was analyzed.Motion procedure after losing control was divided into two steps.One is drift step within stopping period.The other is drift step without inertia,which is induced by wind and current.Mathematical model for motion of ship out of control,considering wind-induced drift,current-induced drift,stopping ability,etc.,was established.Dangerous collision areas for main pier and auxiliary piers were analyzed according to different calculation conditions.
