electric power measurement meaning in English
电功率测量
Examples
- Dft - based analysis of harmonic influence on the electric power measurement
基于离散傅立叶算法谐波对电能计量影响 - When there are harmonics on the power system , influences of measurement process of reactive power caused by harmonic are analyzed , for example the influences of inductor and electric power measurement
电网有谐波存在时，分析了谐波对于无功测量过程的影响，如对互感器的影响，对电能计量的影响。 - In this paper , the application of dsp technology in electric power measurement meter has been studied , meanwhile analysed the error of the electronic energy meter , put forward the measure to compensate error with software method . it not only changes the precision degree of electric power measurement meter , but also avoids the disadvantage from error compensate with hardware method , it is unnecessary to adjust the sample value of voltage and electric current in circuitry
对dsp技术在电度表中的应用进行了研究,对电度表系统的误差进行了分析,提出了采用软件方法来补偿误差的措施,使电度表的精度达到了设计要求,又避免了利用硬件进行误差补偿所带来的弊端,不用在线路中调整电压、电流采样值,有利于生产。 - It is deduced theoretically that non - linear load , rather than linear load , generates harmonics , which translates part of fundamental reactive power absorbed from power system into harmonic reactive power injected into the power system . the rationality of electric power measurement for linear and non - linear load is studied , and as a result some rational advices are addressed here
从理论上推导了线性负载不产生谐波，非线性负载将吸收的部分基波功率转化为谐波功率注入系统，并对电能计量准确性和合理性做了一些探讨，最后提了一些无功的收费意见。
