Abstract (EN):
This chapter presents a rail power conditioner (RPC) system based on
an indirect AC/DC/AC modular multilevel converter (MMC) where a V/V power
transformer is used to feed the main catenary line and the locomotives. The proposed
control strategy for this system has been introduced to guarantee a good compensating
performance of negative sequence currents (NSCs) and harmonics on the public
grid side. This control strategy has also the ability to achieve balanced and equal
voltage between the MMC’s submodules (SMs) capacitors. Simulation results for
this RPC based on an indirect MMC are presented in this chapter to show the main
advantages of using this topology. The results show how the proposed system is able
to compensate NSCs and harmonics on the public grid side when the V/V power
transformer feeds two unequal load sections.
