Spectral analysis of input current and voltage of an O'Z-ELR series alternating current electric locomotive 4q-s converter using a computer simulation model

Study of the traction converter control system of the uzelr series of electric locomotives

“…Unlike the first series of electric locomotives with asynchronous traction motors, in which the electrical equipment of the Siemens company was installed [2,3,8], the new electric locomotives have a different realisation of the motor power system. Thanks to the use of the above-mentioned IGBT modules (Toshiba), which provide reliable power at a relatively low cost, there are separate power lines for each of the motors.…”

“…In 1958, the prototype of the JuLong diesel-electric locomotive was built, based on the Russian TE10 diesel locomotive and the Fairbanks Morse FM38D. with an opposed piston engine, and in 1964 the production of DF class diesel-electric locomotives began [2][3][4][5][6][7][8][9].…”

“…The locomotive control and monitoring system mainly consists of the power supply module, the logical operation control section, the digital I/O section, the analogue signal acquisition section and the communication section in terms of hardware. The main control unit uses a 32-bit CPU and is configured with redundancy and dual hot standby to improve system reliability [8]. The schematic diagram of the system is shown in Fig.…”
