| Abstract: | Through the analysis of system harmonics for the mass transit system, it is proposed to calculate the harmonics in a way ofmathematical resolution. The hypothesis conditions of the current source calculation method are given. Equivalent circuit diagram is producedin diagrams for the harmonic power supply. Mathematical modal is built for the harmonics with mathematical resolution to calculate theharmonic contents and distortion rate of harmonic voltage. |
