| Abstract: | Aiming at the problem of influence of electrified railway operation on the power quality ofGuyuan power grid, analyzes deep the influence factors, puts forward the method of installing static vargenerator(SVG)and high voltage filter capacitor (FC), solves the problems of negative sequencecurrent, harmonic wave, reactive power and load fluctuation produced by the operation of electrifiedrailway. The application result shows that using the method of installing SVG + FC can effectivelyimprove the power quality of power system in the operation of electrified railway. |
