摘　　要：[目的]随着电力电子器件在船舶上的广泛应用和船舶电力系统容量的不断增加,船舶电能质量问题日益突出。为此,设计一种电能质量实时评估系统。[方法]首先,基于电力推进船舶电力系统的特点和船舶电能质量的研究现状,分析主流电能质量评估算法的优缺点与可行性;然后,根据最新评估标准,筛选可以反映船舶电力系统运行特点的8个电能质量指标,构建多层次评估体系,提出基于层次分析法(A HP)模糊综合评估(F CE)法的船舶电能质量实时评估系统;最后,基于电力推进船舶实验装置进行可行性验证,并通过Matlab软件设计相应的图形用户界面(G UI)。[结结果]该评估系统可以实现船舶电能质量的1 s级实时评估打分,同时生成定性与定量2种形式的评估结果。[结论]A HP模糊综合评估法可以成功应用于船舶电能质量的实时评估系统,有利于船舶电力系统设备的集中监测管理,并为其他评估方法在船舶领域的应用提供一种新的设计思路。[Objectives]With the wide application of power electronic devices in electric propulsion ships and the increasing capacity of marine electric power systems,the problem of ship power quality has become increasingly prominent.In view of the issues above,a realtime power quality evaluation system is designed.[Methods]Firstly,the advantages,disadvantages and feasibility of the mainstream power quality assessment algorithms were analyzed based on the characteristics of the electric power system the ships and the research status of the ship power quality.Then,a ccording to the latest evaluation criteria,a multi-level evaluation system containing eight power quality indexes which can reflect the operating characteristics of marine electric power system was constructed and the ship's power quality realtime evaluation system based on the Analytic Hierarchy Process(A HP)-Fuzzy Comprehensive Evaluation(F CE)method was proposed.Finally,the feasibility test based on the electric propulsion ship experimental device was carried out and the corresponding Graphic User Interface(GUI)was designed by Matlab software.[Results]The evaluation system can realize the realtime evaluation and scoring of the ship's power quality at 1 s level and generate qualitative and quantitative results at the same time.[Conclusions]AHP-FCE method can be successfully applied to the realtime evaluation system of ship power quality,w hich is conducive to improving the centralized monitoring and management of marine electric power system equipment and provides a new design idea for the application of other evaluation methods in marine fields.
