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.

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.
