摘要：

为了实现对高压直流继电器性能的评估,提出基于云物元理论的模糊综合评估方法。建立高压直流继电器性能指标评估体系,考虑指标参数的随机性和其等级边界值的模糊性,利用云物元理论确定继电器性能指标的隶属度,并将改进的层次分析法和CRITIC法相结合确定组合权重;根据隶属度和组合权重,得到模糊综合评估模型。最后,通过高压直流继电器性能评估实例分析,验证了方法的有效性。

Abstract:

In order to evaluate the performance of HVDC relays,a fuzzy comprehensive evaluation method based on cloud matter-element theory was proposed.Firstly,the evaluation system of the performance index of HVDC relay is established.Due to the randomness of the index parameters and the fuzziness of its rank boundary value,the cloud matter element theory is used to determine the membership degree of the relay performance index,and the improved analytic hierarchy process (AHP) and the CRITIC method are combined to determine the combination weight,then according to the membership degree and the combination weight,the fuzzy comprehensive evaluation model is obtained.Finally,the effectiveness of the method is verified by an example of performance evaluation of HVDC relay.

Key words: fuzzy comprehensive evaluation method, HVDC relay, cloud matter-element theory, AHP, CRITIC method
