Abstract
All state-of-the-art Power Electronic Traction transformers (PETT) were developed for the existent Medium Voltage (MV) AC Electric Railway Systems (ERS). This work, however, presents a PETT for a novel MVDC-ERS. We studied and evaluated various state-of-the-art PETT topologies in two previous articles to determine which is best for this application, and we presented an 8-module Input Series Output Parallel (ISOP) MVDC PETT with a total power exceeding 1.2 MW. The converter topology used in the modules is the Dual Active Bridge (DAB). In this paper, the complete mathematical model of the converter, the deduction of controller parameters and the decoupling method, and the simulation model are presented in detail. Simulations show how the system works and interacts with a traction motor, as well as its response to input voltage variation and load steps. The results and theoretical notions obtained in this project will lay the foundation of a novel smart MVDC-ERS, meanwhile an experimental prototype is under development. |
