| 摘 要： | 目前对非正弦无功电能计量的研究还很不完善。为了能够准确地理解和计算非正弦电路的无功功率,导出了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,并提出了一种基于低通滤波器的含有非线性无功功率的计量方法。依据IEC1268标准的技术条件给出了两种无功测试方法测量误差的试验数据,从而得出了低通滤波器方法测量无功功率是一种较好的方法的结论。

| Abstract: | At present the research of influence of the reactive power in the nonsinusoidal electric circuit on reactive energy measurement is still imperfect.In order to understand and calculate the reactive power of the nonsinusoidal electric circuit accurately and analyse 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.The physical meaning of every item in formulae is analysed.A new method of Reactive Energy Measurement including nonsinusoidal reactive power based on low pass filter is presented.And it presents the measurement error experimental data of two kinds of reactive power measurement method based on the IEC1268 standard technology condition,consequently has concluded the low pass filter reactive power measurement method is a better one. |
