摘要
对雷达图法进行了改进,并应用于电能质量的综合评估中。改进的雷达图法首先对各指标的权值进行排序,进而依据该排序结果对雷达图中指标对应的扇形区域进行排序和分配扇形的角度,利用各指标对应的扇形区域的对角线作为指标轴绘制雷达图,不仅最大限度地反映了各指标的独立权重,而且也反映了各指标之间的相互影响和作用。改进了评估算法,利用所绘制雷达图的面积和周长2个变量完成对电能质量的综合评估。验证结果表明,所提方法具有较好的可行性。
The radar chart method is improved and applied to the synthetic evaluation of power quality.The index weights are ranked,and based on which,the corresponding sector areas are ranked and their angles are distributed.The diagonal of the sector area is taken as the corresponding index axes to draw the radar chart,which reflects both the unattached weight of every index and the influences among each other.The evaluation algorithm is also improved,which applies the area and girth of radar chart to synthetically evaluate the power quality.Verification results show its better applicability.
