| Abstract: | The paper presents an analogue digital composite sampling method,gives two kinds of algorithms and analyzes the errors of the algorithms.At the same time,the paper analyzes the effects of quantizing error on the two kinds of algorithms,linear error on the power and voltage measurement.Compared with the old sampling algorithm,the new sampling algorithm has made measurement accuracy significantly improved and makes power measurement accuracy as high as 0.03% |
