Abstract

Describes a system involving a hardware interface, a PC, and advanced software to measure, analyze, and report the condition of harmonics on the power system. The results showed that the harmonic content of the load waveform affects power measurement significantly. It is possible with sample data techniques to determine true real power consumed by the power distribution system, or to resolve poor power factor questions. It is noted that the system developed for the measurement and analysis of harmonic effects on power metering has greatly reduced the effort needed to study and solve the problem of power measurement in the presence of harmonic distortion.<>

数字微处理器技术在谐波环境下电力计量中的应用
描述了一个系统,包括硬件接口、PC机和先进的软件来测量、分析和报告电力系统的谐波状况。结果表明,负载波形的谐波含量对功率测量有显著影响。使用样本数据技术可以确定配电系统所消耗的真实功率,或者解决功率因数差的问题。文中指出,为测量和分析谐波对电力计量的影响而开发的系统,大大减少了研究和解决存在谐波失真的电力计量问题所需要的努力。
