摘　　要：当前风险自动预警系统通常采用基于经验值的人工方法设置自动预警阈值,给出的是统一阈值,导致系统虚警率较高。因此,提出基于模糊聚类特性的电网运营风险自动预警系统。设计信息采集器和显示器,应用决策级融合原理和神经网络模型,整合实时采集的电网运营多源异构数据。从购电维度、输配电维度和售电维度入手,确定电网运营风险度量指标,得到风险度量结果。依托模糊聚类特性建立动态聚类图,对风险预警对象进行分类,分析电网运营风险的内容,作为自动预警阈值。根据预警阈值定义风险自动预警线,对比风险度量结果生成包含预警等级的自动预警信息。实验结果表明,所提系统的虚警率为2.67%,满足了电网运营风险自动预警要求。The current risk automatic warning system usually uses manual methods based on empirical values to set automatic warning thresholds,which provide a unified threshold,resulting in a high false alarm rate in the system.Therefore,a power grid operation risk automatic warning system based on fuzzy clustering characteristics is proposed.Design information collectors and displays,apply decision level fusion principles and neural network models,and integrate real⁃time collected multi⁃source heterogeneous data of power grid operations.Starting from the dimensions of power purchase,transmission and distribution,and sales,determine the risk measurement indicators for power grid operation and obtain the risk measurement results.Based on the fuzzy clustering characteristics,establish a dynamic clustering graph to classify risk warning objects,analyze the content of power grid operation risks,and use it as an automatic warning threshold.Define the risk automatic warning line based on the warning threshold,and generate automatic warning information containing warning levels by comparing the risk measurement results.The experimental results show that the false alarm rate of the proposed system is 2.67%,which meets the requirements of automatic risk warning for power grid operation.
