基于态势感知的电网台风预警防御框架研究综述

鉴于态势感知在电力系统的应用和发展,对基于态势感知技术的电网台风预警防御框架进行研究,以应对近年来频发的台风灾害。基于态势感知的3个阶段对台风预警防御框架的主要研究内容和关键技术进行归纳。在态势要素采集环节对台风预警防御系统需采集的信息进行了拓展和总结。基于所获取的数据,在态势理解环节对电力设备的静态故障率和电网的韧性进行实时评估,以实时感知电网的运行状态。在未来态势预测环节,在预测和修正台风的路径及风速的基础上,对台风灾害下电网的运行风险评估方法进行归纳分析,包括单个故障、群发性故障和连锁故障的风险预测。最后,总结了基于态势感知的电网台风预警防御的整体框架,并对台风预警防御框架的未来发展方向进行展望。

Research on typhoon early warning and defense framework of power grid based on situation awareness

In view of the application and development of situation awareness in power system, the typhoon early warning and defense framework based on situation awareness technology is studied in order to cope with the typhoon disaster frequently happened in recent years. This paper summarizes the main research contents and key technologies of the typhoon early warning and defense framework based on the three stages of situation awareness. Firstly, the information needed to be collected in typhoon warning and defense system is summarized and developed in the situation elements collection stage. Secondly, based on the data obtained, the static failure rate of power equipment and the resilience of the grid are assessed real-timely to sense the operating status of the power system in the situation understanding stage. Thirdly, based on the prediction and correction of the typhoon path and wind speed, the risk assessment method of the grid under the typhoon disaster is summarized in the future trend prediction stage, including the risk prediction of the single fault, the mass fault and the chain fault. Finally, the overall framework of typhoon early warning and defense based on situation awareness is summarized, and the future trend of typhoon warning and defense framework is forecasted.
