基于 IEC 61850标准的数字化电能表丢帧误差分析
Frame loss error analysis of digital Watt-hour meter based on IEC 61850
摘要
Abstract
As a key device of digital power metering system , the error of digital watt-hour meter directly determines the accuracy of the digital power metering system , the digital Watt-hour meter has a lot of differences from traditional Watt-hour meters in the form of signal input , the input signal of traditional Watt-hour meter is three-phase analog volt-age/current and the digital Watt-hour meter is data frame that follows the IEC 61850 protocol , so compared With tra-ditional Watt-hour meter , the digital Watt-hour meter has an important error source-frame loss error .This paper ana-lyzed the frame loss error of digital Watt-hour meter in theory , and derived the maximum allowed frame loss rate to digital Watt-hour meter that determined level , at last, through experiment and simulation verification , it is found that the frame loss error of digital Watt-hour meter changes with the number of lost frame , and the maximum loss error has nothing to do with the sampling frequency .It is concluded that to ignore the digital power metering system loss error , the maximum allowable frame loss rate of digital Watt-hour meter should below 5% of accuracy level , and it has an important significance to set up relevant surveillance project for digital Watt-hour meter .关键词
