Power grid accident alarm method and system based on three-risk linkage

The invention provides a power grid accident alarm method and system based on three-risk linkage, and belongs to the field of accident prediction. According to the technical scheme of the invention, the power grid accident is alarmed by integrating the equipment risk, the power grid risk and the operation risk, and the equipment risk index is predicted from five dimensions and the importance degree of the equipment. The method comprises the following steps: predicting an operation risk value from the perspective of an individual portrait of an operator and a basic risk value and complexity of an operated device, predicting a power grid accident and an occurrence probability based on a historical power grid data sequence, and training and extracting rules of various risks by adopting a machine learning model in the prediction process, and the power grid accident is predicted by integrating three aspects, so that the prediction result is more accurate. 本申请提出的一种基于三险联动的电网事故报警方法及系统，属于事故预测领域。本申请的技术方案综合设备风险、电网风险和操作风
