摘要
为提高继电保护设备状态评价的精度,基于保护屏本体、保护回路和保护通道构建了多层次继电保护设备状态评价指标体系,设计了基于模糊层次分析法的继电保护设备运行状态评价模型。实验结果表明,与层次分析法和模糊评价法相比,模糊层次分析法具有更高的评价准确率。
In order to improve the accuracy of the evaluation of the status of the relay protection equipment,this paper constructs a multi-level evaluation index system for the status of the protection equipment based on the protection screen body,and designs the protection circuit and the protection channel,and the evaluation model of the operation status of the protection equipment based on the fuzzy analytic hierarchy process.The experimental results show that,compared with analytic hierarchy process and fuzzy evaluation method,fuzzy analytic hierarchy process has higher evaluation accuracy.
