数字化变电站合并单元插值误差对于电能计量的影响
The influence of merging unit interpolation error in digital substation on electric energy measurement
摘要
Abstract
As a link between the electronic transducer and the secondary device, the merging unit is responsible for providing a unified voltage and current data source for the substation.However, the sampling value in data sampling, processing and transmission links generated in large data, communication delay and packet loss and other issues will be on the merging unit interpolation processing effects, and ultimately affects the measurement of electric energy.Based on the above typical issues of merging unit of interpolation algorithm, the impact of electrical power measurement error is analyzed, and the simulation results were verified by building the error test system of electric energy metering device in digital substation.The results show that the typical problems of interpolation play significant impact on the merging unit and the measurement error of electric energy, and the different interpolation algorithms have different effects results.This paper provides a quantitative reference for the design and optimization of interpolation algorithm for merging unit in digital substation.关键词
