摘要
针对目前智能变电站通信网络状态评估难、网络复杂等问题,在智能变电站体系结构的基础上,提出了一种模糊理论用于智能变电站通信网络状态综合评价.采用隶属函数将元素转化为隶属度,并结合层次分析法和斯皮尔曼相关系数法确定权值,根据隶属度和权值得到综合评价结果.通过算例对不同情况进行对比分析,验证了该方法的优越性.结果表明,该方法可以反应整个通信网络的状态,也可以进一步反映负荷状态、报文传输效果等,为系统状态的维护提供一定的依据.
Abstract
Aiming at the problems of difficult and complex communication network state evaluation of intelligent substation,based on the architecture of intelligent substation,a fuzzy theory is proposed for the comprehensive evaluation of communication network state of intelligent substation.The elements are transformed into membership degree by membership function,combined with analytic hierarchy process and Spearman correlation coefficient method to determine the weight,the comprehensive evalua-tion results are obtained according to the membership degree and weight.Through the comparative analysis of different cases,the superiority of this method is verified.The results show that this method can not only reflect the state of the whole communication network,but also further reflect the load state and message transmission effect,which provides a certain basis for the maintenance of system state.
