摘　　要：常规的电网全景式运行状态评估,主要采用电网状态量数值建立评估矩阵得到评估结果,忽略了电网数据差异度对于评估结果的影响,导致评估结果的可靠度较低。因此,提出基于多图层模型的电网全景式运行状态评估方法。先清洗数据,计算有序区间,判定其一致性,降低差异度影响,构建评估模型,分别计算基础指标并确定权重,得出结果。实验显示,该模型的可靠性较高(均值0.92),满足电网运维工作的需求。The conventional panoramic operation status evaluation of the power grid mainly uses the numerical values of power grid state variables to establish an evaluation matrix to obtain evaluation results,ignoring the influence of power grid data differences on the evaluation results,resulting in low reliability of the evaluation results.Therefore,a panoramic operation status evaluation method for power grids based on multi-layer models is proposed.First,clean the data,calculate the ordered interval,determine its consistency,reduce the influence of dissimilarity,construct an evaluation model,calculate the basic indicators separately and determine the weights,and obtain the results.The experiment shows that the reliability of the model is high(mean 0.92),which meets the needs of power grid operation and maintenance work.
