基于自主式决策的综合评价方法在电能质量领域的分析与运用

An Autonomous Decision-Making Based Method for Comprehensive Evaluation of Power Quality and Its Application

提出一种基于自主式决策思想的区域电能质量综合评估方法,在解决了指标权重主观性的同时,实现了对于同一区域不同评估对象电能质量综合评价结果的相互比较。首先,该算法对各评估对象采取了"突出自身优势,弱化对手优势"的竞争原则;接着以自主式决策方法分析了电能质量评估对象的竞争区间以及竞争视野,构建了具有竞争特点的评价模型;最后得出了各评估对象合理的评估排序结果。具体算例表明,该方法体现了评估对象的自主性作用,保证了评价结果的公正性、有效性。

It is the first time that an autonomous decision-making based method for comprehensive evaluation of power quality in regional power network is proposed. Using the proposed method, the intercomparsion between comprehensive power quality evaluation results of different objects to be evaluated in the same region can be implemented while the problem of the subjectivity of index weights is solved. Firstly, a competition principle of strengthening self-advantage and weakening rival＇s advantage for the objects to be evaluated is adopted in the proposed algorithm; then by use of autonomous decision-making, the competitive interval and view of power quality evaluation objects are analyzed and an evaluation model with the property of competition is built; finally rational sorting results of evaluated objects are obtained. Results of concrete calculation example show that the proposed method can incarnate the autonomous action of evaluated objects and both faimess and effectiveness of evaluation results can be ensured.
