摘要
本文讨论了一种新的非正弦波周期电信号的有功功率采样法测量的误差计算法。利用这种新的误差计算，能计算同步误差、采样点数等对测量误差的影响，计算机实验表明，测量误差与同步误差成线性关系。本方法适应于各种非正弦周期信号的误差估算，和其它方法相比，本方法具有更大的实用价值。
A new sampling error counting for measuring active power of nonsinusoidal periodic electricsignal is discussed in the paper,With this new error counting,we can calculate the effects ofsynchronization error and the number of sample the error of measurement. Experiments on acomputer proved that the results of measurement have linear relation to synchronisation error. Themethod is suitable for error counting to various nonsinusoidal periodic sisnal. Compared with othermethods,the new method has more value,in practice.
