摘要
首先对电能质量指标实测数据进行了区间估计;其次对电能质量指标进行了熵权系数确定;最后建立了区间数逼近评估模型对电能质量进行客观的评估。通过实例表明,基于熵权区间数逼近的算法能够对不同时段的电能质量进行整体评估。
Firstly,it made an interval number approximation for the real-time measured data of power quality indicators.Secondly,it carried out an entropy weight determination for the power quality indicators.Thirdly,it established an interval number approximation assessment model to take an objective assessment for the power quality.The test showed that the algorithm based on the method of entropy weight and interval number approximation could carry out an entire assessment for the power quality in different periods.
