| 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. |
