Abstract
A modeling method of designing parameter of passive power device is presented. The work conditions of passive power device were modeled and analyzed according to Thevenin theorem and Norton theorem, respectively. Under the perturbation of source impedance and frequency of the power system, changes in fundamental current of inject into every filter of passive power device was analyzed based on numerical method. Expressions of harmonic current of inject into every filter of passive power device were given through character calculation. The numerical analysis and practice measure show that, the harmonic currents of inject into power system accord with national criterion GB/T-14549-93 and its power factor is increased to 0.94 from before 0.82.
