The Application of the Double Domain Simulation by Different Harmonic Filtering Methods of 25 kV Electric Traction Systems

The paper shows the present results of along term research work The authors are working on the modeling of penetration and elimination of harmonic disturbance. originating from the high power railways. This paper presents the application of the so called double domain simulation method, which is a combination of frequency and time dependent model. This novel method is used to improve the accuracy of the frequency domain simulation. The double. domain simulation is suitable for studying the different filtering methods, both the passive, active and hybrid filtering. This paper would like to give an overview about the application of filtering possibilities using the. double domain simulation method.
