直流纹波对直流电能表的影响分析
Analysis on Influence of Direct Current Ripple Wave on Direct Current Electric Energy Meter
摘要
Abstract
For measuring direct current (DC)electric energy,one method is to use a DC voltage meter and a DC current me-ter to measure its effective values respectively and then work out the electric energy value after multiplying the two effective values and getting its DC power. Another method is to carry on synchronous sampling for voltage and current and use instan-taneous power integration to calculate the electric energy value. Because DC signals overlay ripple signals,it is able to ana-lyze influence by DC ripple wave on measuring errors by means of theoretical analysis and design simulation which may pro-vide theoretical reference for DC tracing to the source and DC measuring.关键词
