研究分析結果表明:感應式電能表的誤差頻率特性曲線呈迅速下降趨勢,因此在電能計量中,不管是以全能量為計量標準還是以基波能量為計量標準,當諧波含量較大時對感應式電能表的電能計量將會產生較大的影響。Compared with the induction meter, the electronic meter ' s measurement error is affected diminutively by the change of the frequency, that is to say, the electronic meter has a wide frequency respond characteristic and its error - frequency characteristic curve is flat. therefore, taking the whole energy as measurement standard, the measurement error of electronic meter is less than that of induction meter very much ; while the measurement error of electronic meter is bigger than that of induction meter when taking the basic energy as measurement standard
和感應式電能表相比,電子式電能表的計量誤差受頻率變化影響較小,具有較寬的頻率響應,誤差頻率特性曲線較為平坦,因此,在諧波存在下以全能量為計量標準時,電子式電能表的計量誤差遠遠小於感應式電能表的電能計量誤差,而以基波能量為計量標準時,電子式電能表的計量誤差比感應式電能表的計量誤差大。Due to temperature performance of fbg, a reference fbg is adopted to compensate temperature and the compensation principle is expounded. moreover, this scheme not only realizes temperature compensation but also reduces repeatability error of ffptf and errors from power fluctuation of light source, noise of pd and noise of electro - circuit. in the end, temperature and strain performance of fbg is tested and
