Traction Machines and Propulsion Systems
Normally a propulsion system for Rail vehicles in a DC traction power supply is simpler and slightly cheaper than the propulsion system for a AC traction power supply. Also, there is another comparison between AC propulsion versus DC propulsion. At the moment, a broad range of various propulsion systems operates in Australia and similarly all around the world. AC and DC propulsion for every type of power system , Diesel locomotive, AC traction power supply and DC traction power supply is performing under service.
My Practice Areas
There are lots of sample/reference packages and documents accomplished by me in my previous works and projects, you welcome to download and check them.
Key power components of a Propulsion System
No matter what type the propulsion system is, key components shall be identified according to the following itemised groups:
Types of Components in a typical Propulsion System
So, abstracting from above table, there are two main types of equipment in all groups of propulsion systems.
Power electronic equipment such as converter and inverter in order to convert different forms of electrical power and control it
Rotating electric machines such as alternator and traction motor to convert electrical-mechanical power and provide movement.
