模糊综合评价方法在变电站通信网络状态检修中的应用

针对变电站通信网络系统的复杂性,并难以进行精确的状态评价这一问题,应用模糊数学理论,结合变电站的实际情况和发展趋势将通信评价系统根据需要分成若干个指标,建立了因素集、评价集,在此基础上,采用岭形分布作为隶属函数,并利用层次分析方法量化权重,提出了采用模糊综合评价方法来实现对变电站通信网络状态的综合评价.实例表明:模糊综合评价方法可操作性强,效果较好,可在变电站二次设备状态检修中广泛应用.

Application of fuzzy comprehensive evaluation to substations communications network state evaluation

In view of the substation communications network system for complex and difficult problem of precise evaluation of the state,and based on fuzzy mathematics theory,the fuzzy comprehensive evaluation is applied to the state maintenance of transformer substation communications network,combining the actual situation list to evaluate the general level of transformer substation communications network by fuzzy comprehensive evaluation.By setting up the factor sets,the evaluation sets,and on the basis,by using the ridge-shaped distribution as membership functions,and using AHP to quantify the weight,a fuzzy comprehensive evaluation method is put forward to achieve the status of substation communication network evaluation.Example shows that fuzzy comprehensive evaluation method can be widely used in the state of maintenance of substation equipments.
