Hey,
So I'v been working on my final year project for electrical engineering and my topic is electric railway (ER) systems. I'm simulating a newer model train (EMU) on a train line in Perth Western Australia in MATLAB. I am coming close to the finishing the simulation...just having some difficulty coming up with a power conditioning system for the EMU motors.
Here is my stuff so far:
The red blocks are the EMUs, the orange blocks are measurement and control sub systems for turning on the EMU loads as they move away from the supply. The blue blocks are the traction line equivalent impedance.
This is the subsystem blocks for the B-series EMU
Here is my issues
(1) I don't know how to make a load that draws current
(2) Using IGBT inverters seems unnecessarily complex for my simulation. Could I use a uncontrolled type inverter?
(3) I am having some serious difficulty trying to calculate and imagine the waveform as it goes through the conditioning stages. From what I understand, with the given system. it should be a positive cycle full wave after the four quadrant rectifier then smoothed to DC, then converted to 3 phased AC...
What do you think?
