| Abstract: | The necessity to govern the harmonic wave is analyzed from the aspects of the definition,national standards,procreant reasons and the harms of harmonic wave to various equipments in subway power supply system.According to the government plan of harmonic wave in Xi’an subway supply system,the application of low pressure active electric power filter in the harmonic wave government is introduced.Through a simulation and the theoretical analysis,the feasibility of the government plan is confirmed,which will guarantee the guide line of electrical energy to satisfy national standards. |
