摘要
为了解决传统方法中未考虑多参量指标对电能质量的影响、电能质量计量结果准确度较低等问题,提出基于射频识别技术的电能质量计量评估模型。利用射频识别技术采集电能质量EPC码,获取电能质量计量评估数据,并以电流总谐波畸变率、三相不平衡和频率偏差等为计量评估指标进行权重计算,获取各项指标综合权重值;引入雷达图分析方法,比较电能质量的多变量,定义综合性的评估函数,反映电能质量情况,实现电能质量综合性评估。以评估稳定性和评估准确性为实验指标的实验结果显示,该模型可实现电能质量的高精度评估,实际应用的可靠性较强。
In order to solve the problems of traditional methods,which do not consider the influence of multi parameter indexes on power quality and low accuracy of power quality measurement results,a power quality measurement and evaluation model based on RFID technology is proposed.The power quality EPC code is collected by using RFID technology to obtain the power quality measurement and evaluation data,and the total harmonic distortion rate of current,three-phase imbalance and frequency deviation are taken as the measurement and evaluation indexes to calculate the weight and obtain the comprehensive weight value of each index;the radar chart analysis method is introduced to compare the multi variables of power quality,and the comprehensive evaluation function is defined to reflect the power quality to achieve comprehensive power quality assessment.The experimental results,which take the evaluation stability and accuracy as the experimental indicators,show that the model can achieve high-precision evaluation of power quality.The reliability of practical application is strong.
