Controlling a doubly-fed induction machine for propulsion and charging of wireless powered rail transportation

Traditional trains, with steel rails and wheels, have been around for centuries. The very good energy efficiency of steel-wheeled trains is one of the reasons that they are one of the more promising transportation modes in the future, where energy conservation becomes more and more important. Furthermore, electric trains are able to efficiently...

Testing of Fast Transfer Relay by an EMTP-based Approach

Industries such as chemical companies need a continuous power supply and the fast transfer relay Siemens 7uv68 is designed to transfer frompresent feederwhich encounters a fault to an auxiliary feeder and minimizes the transient torque of the induction motors during transfer. The relay will be installed in a DOW power plant in South Tarragona,...
