摘要
为解决现有电能计量表稳定性不足问题,采用时间频率领域守时系统中的AT1算法,建立类似于原子钟组的标准电能表组,通过对该标准电能表组中各电能表读数进行加权处理,得出最终的电能量值.研究结果表明:经过AT1算法处理得到的电能量值和单独的电能表相比具有更小的误差方差;通过偏移纠正可以降低误差造成的影响,提高目前电能计量标准装置的准确度.研究结论验证了AT1算法在电能量值计算中的有效性和指标选取的合理性,为相关电能计量技术的推广应用提供了理论基础.
In order to solve the problem of insufficient stability of the existing electric power meter,a standard electric power meter group similar to the atomic clock group is established by using the AT1 algorithm in the time-frequency domain punctual system,and the final electric power meter value is obtained by the weighted standard energy meter group values.The research results show that the electric power value obtained by the AT1 algorithm has a smaller error variance than that of the individual electric power meter,and the offset correction can reduce the influence of the error as well as improve the accuracy of the current power meter.The research verifies the validity of the AT1 algorithm in the calculation of electric power value and the rationality of index selection,which provides a theoretical basis for the popularization and application of related power measurement technology.
