| 摘 要： | 为了能够准确地理解和计算非正弦电路的无功功率,分析非正弦无功对无功电能计量的影响.本文采用傅立叶分析方法,导出非正弦电路的无功功率的计算公式,分析了公式中每一项的物理意义,并就非正弦无功对目前主要的两种无功电能计量技术(电磁感应式无功电能计量技术,电子式无功电能计量技术)的影响进行了理论分析,得出在IEEE100-1996标准给出的无功功率定义下,用两种无功电能计量技术测量无功均会产生较大偏差的结论.

| Abstract: | In order to understand and calculate the reactive power of the nonsinusoidal electric circuit accurately and analyses the the influence of the reactive power in the nonsinusoidal electric circuit on reactive energy measurement .The calculation formula of the reactive power is concluded by means of the Fourier analysis method. The physical meaning of every item in formulaes is nalysed. Finally the article analyses the influence of the reactive power in the nonsinusoidal condition on two primary reactive energy measurement technology. The analysis show that reactive power definition produces which in the standard IEEE 100-1996, having a bigger deviation with two kind of reactive energy measurement technology to measure reactive energy. |
