| Abstract: | In light of the harmonic waves problem in urban rail transit power system,which is harmful to electric power supply,this paper points out that one of the best methods to solve the problem is to utilize 24-pulse system in urban rail transit power system,and explains the relationship between harmonics and rectifiers.Based on the related theory of harmonics,if there are more pulses,there will be low harmonics and less harms to the power grid.The same is with the theory of rectifiers: more pulses,more high fact... |
