摘要
针对电力参数测量中因附加相位引起的功率测量误差,提出了一种简单易行的功率算法的修正方法。通过对有功、无功的测量原理和测量系统中的硬件条件,分析了相位误差产生的原因,重点介绍了功率算法的修正原理,实验表明修正后的功率精度优于校正前。
This paper presented a easy correction method of power as to the additional phase caused by power measurement error.the reasons caused by additional phase was analyed through power measurement theory and hardware structure in this system.Detailed on the powercorrection theory.Experiments shows the corrected powerprecision than before.
