基于改进二元语义的配电网工程应急能力评估

Emergency Capacity Evaluation of Distribution Network Engineering Based on Improved Two-tuple Linguistic Information

为实现对配电网工程应急能力的科学评估,提高电力系统应对突发事件的能力,建立了基于改进二元语义的配电网工程应急能力评估模型。首先,在借鉴相关研究成果的基础上,结合配电网应急业务的特点,从四个方面构建了配电网工程应急能力评估指标体系;然后,采用区间数特征根法(IEM)确定评价指标的权重;最后,利用改进二元语义的配电网工程应急能力评估模型对某配电网工程的应急能力进行计算与评估。结果表明:该模型的评估结果与实际情况基本相符,能够快速、真实地反映配电网工程的应急能力水平,可为配电网工程的应急管理提供依据。

In order to evaluate the emergency response capability of distribution network engineering and improve the emergency response capability of power system,this paper establishes a model of emergency response capability evaluation of distribution network engineering based on improved two-tuple linguistic information.Firstly,on the basic of referring to relevant research and combining with the characteristics of distribution network emergency services,the paper constructs an evaluation index system of distribution network engineering emergency capacity from four aspects.Secondly,the paper applies interval number characteristic root method (IEM) to determining the index weight.Finally,the paper applies the emergency capacity evaluation analysis model of improved two-tuple linguistic information to calculating and evaluating the emergency response capability of a distribution network project.The results show that the evaluation results of the model are basically consistent with the actual situation,and can quickly and effectively reflect the emergency capacity level of distribution network engineering.The results also can provide the basis for emergency management of distribution network engineering.
