中文摘要:
      针对目前无功功率计量算法在非正弦不平衡条件下的无功功率计量方面准确性的不足,本文在Fryze时域无功定义的基础上提出了一种适用于非正弦不平衡三相三线制系统的无功功率计量理论。根据Fryze时域无功定义将三相瞬时电流分解为有功电流分量和无功电流分量,并对三相瞬时电压和无功电流分量进行快速傅里叶变换,得到各次谐波无功功率的大小和方向,从而实现对非正弦不平衡三相三线制系统无功电能的准确计量。该方法将无功功率分为正向无功功率和反向无功功率,避免了同一谐波源产生的不同次数谐波的感性无功与容性无功相互抵消的情况。最后通过Matlab仿真验证了这一结论,为非正弦不平衡条件下系统无功电能的准确计量提供了理论依据。
英文摘要:
      In allusion to the lack of accuracy of reactive power measurement methods at present under the condition of non-sinusoidal and asymmetry, this paper puts forward a reactive power measurement theory which is applicable to three-phase three-line system under the condition of non-sinusoidal and asymmetry based on Fryze’s reactive power theory in time-domain. According to Fryze’s reactive power theory in time-domain, three-phase instantaneous current can be decomposed into active current component and reactive current component. Then the value and direction of reactive power of each harmonic can be achieved by FFT analysis on three-phase instantaneous voltage and reactive current component so as to realize the accurate measurement of reactive power of three-phase three-line system under the condition of non-sinusoidal and asymmetry. In this method, the reactive power are divided into positive reactive power and negative reactive power to avoid the offset of inductive reactive power and capacitive reactive power under different harmonic frequency generated by the same harmonic source which is finally verified by Matlab simulation and provides theory basis for accurate measurement of reactive power under the condition of non-sinusoidal and asymmetry.
