摘要
随着测量技术进步和电力系统管理水平的提高,无功电能计量理论技术得到了很大发展,一方面针对电力系统特性的变化提出了新的无功电能计量理论,另一方面随着微电子技术的进步形成了多种无功电能计量新技术。本文在阐述正弦无功功率理论与正弦无功电能计量技术的基础上,介绍了非正弦无功功率理论和非正弦电能计量技术,并探讨了无功功率理论和无功电能计量技术的发展。
Along with the progress of measuring techniques and increase in the rnanagement levels of power systems, the theories and techniques foe reactive energy measurement have a great development.On the one hand, some new reactive energy measurement theories are presented according to characteristic changes of power systems.On the other hand, many advanced reactive energy measure techniques are developed with the progress d mlcro-electronic technologies.In this paper, after the sinusoidal, reactive power theory and the sinusoidal reactive energy measuring techniques are expatiated, an emphasis was given upon the investigation of non-sinuaoidal reactive power theories and non-sinusoidal reactive energy measuring techniques. Finally, the developments d reactive power theories and reactive energy measuring techniques are discussed.
