基于区块链技术的电网灾害预警决策系统
摘要：为了进行电网自然灾害风险预警，减少自然灾害对电网的影响，研究了基于区块链(block chain，BC)技术的电网灾害预警决策系统。首先，根据电网与自然灾害之间的耦合作用关系，挖掘电网智能设备采集数据及自然气象等信息资源，搭建了区块链支持的电网灾害预警决策系统的总体架构。然后，以电网冰灾为例，根据气象预报和微地形等信息，利用模型预测控制(model prediction control，MPC)算法修正了电网输电线路覆冰模型，建立了由线路覆冰过重、舞动以及绝缘子闪络引发的线路故障概率模型。最后，通过MPC算法求解输电线路覆冰预警模型，实现了线路故障预警。以某市西北部和中部几条220kV线路为例进行覆冰预测分析，验证了提出的基于区块链的电网灾害预警决策系统对覆冰厚度进行预测的可行性和有效性。
Abstract:To effectively implement early warning of natural disaster risk for power grid and furthest reduce the affect of natural disaster on power grid, a block chain technology based power grid disaster early warning and decision making system was researched. Firstly, according to the coupling relationship between power grid and natural disaster, the information resource such as the data collected by power grid intelligent devices and natural meteorological information and so on were mined to construct the overall architecture of power grid disaster early warning and decision making system supported by block chain. Secondly, taking the ice disaster occurred in power grid for example, according to weather forecast, microtopography information and so on and by use of model prediction control (MPC) algorithm the ice-coated model of power network transmission line was revised, and the probabilistic model of transmission line fault caused by overweight of ice-coating, transmission lines galloping and insulator flashover was established. Finally, the early warning model of ice-coated transmission line was solved by MPC algorithm to realize the early warning of transmission line. Taking several 220 kV transmission lines located in the central and north-west regions of a certain city for example, the predicted analysis on ice-coating was carried out, and the feasibility and effectiveness of utilizing the proposed block chain based power grid disaster early warning and decision making system for the forecasting of the ice-coated thickness on transmission line are verified.
