摘　　要：由于变频输油电路中,存在谐波电流,并产生畸变功率N,为此以电工理论为基础,确定了畸变功率N、有功功率P、无功功率Q和视在功率S构成的功率四边形,得出了计算畸变功率N、谐波电流、功率因数、畸变角等物理量的方法。并运用功率四边形理论,对现场工程实例进行了有关计算。In oil transferring system with frequency variation,existing harmonics current may result in distortion power N.For this,based on the electro technology theory,determined are the power quadrangle constituted by the distortion power N,active power P,reactive power Q and apparent power S,obtained is the calculation method of the distortion power N,harmonics current,power factor and distortion angel,and relevant technical data from an example are calculated by the power quadrangle theory.
