摘　　要：传统基于多Agent的电力系统抗震脆弱性评估模型,对电力系统抗震脆弱性实施分析时,未考虑节点权重的分配情况,评估效果不理想。因此,设计基于层次分析法的电力系统抗震脆弱性评估模型,基于电力系统节点服务类型和拓扑位置,构建抗震脆弱性评价指标的层次分析模型,基于该模型设置节点权值分配方案,依据该方案采用层次分析法获取风险综合指标,对节点脆弱性指标实施运算,采集不同状态下的各节点脆弱性权值并进行平均运算,获节点脆弱性指标值。基于节点脆弱性指标值,通过层次分析法实现电力系统抗震脆弱性评估。实验结果说明,所设计模型的抗震脆弱性评估结果精度和效率高。Traditional multi Agent based seismic vulnerability assessment model of power system does not consider the distribution of node weight when analyzing the seismic vulnerability of power system, and the evaluation result is not ideal. Therefore, the seismic design of power system based on AHP model of vulnerability assessment, service node type and location based on power system topology, construct the vulnerability evaluation index AHP model for seismic, node weight distribution scheme set based on the model, according to the scheme, using the analytic hierarchy process to obtain comprehensive risk index, vulnerability index of nodeimplementation operation, acquisition of each node under different conditions of vulnerability and average weight, won the node vulnerability index value. Based on the index value of node vulnerability, the seismic vulnerability assessment of power system is realized by analytic hierarchy process（ AHP）. The experimental results show that the seismic vulnerability assessment results of the designed model are of high accuracy and efficiency.
