Abstract
With the development of high-speed railway, harmonic amplification and resonance problems of traction network caused by high-speed locomotive are getting more serious. In order to study the harmonic transmission characteristic of the traction network, the equivalent circuit model of traction network was built in this paper. The suppression method of harmonica current amplification by installing a LC filter branch in the auxiliary winding of traction transformer was proposed in this paper. The parameter selection method of the LC filter branch was also given. At the end of this paper, results from theoretical calculations and simulations are presented, demonstrating the validity and practicality of the proposed suppression method. And this research has reference value for reducing and avoiding the harm of traction resonance.
