因正、负序功率分量之和可由通常采用的“二瓦特表法”获得，于是正、负序功率分量即可析离开来。
Since the sum of these two power components can be obtained by the usually used "two Wattmeter method" , then the components can be Separated.
在三相系统中，以正序基波功率的积分作为计量标准，同样可以消除这两方面的不利影响。
These disadvantages could be eliminated in three-phase systems if the energy account based on the integral of the active power of the positive sequence component with the fundamental harmonic.
论述了利用瞬时无功功率理论从三相不对称电流中正确检测出三相正序有功电流，并用计算出的指令电流对系统进行补偿的原理。
Based on the instantaneous reactive power theory the method correctly detects the active positive-ord current from unsymmetrical currents and applies calculated command current to compensate system.
