New power sources for traction electric drive of dump trucks

Article preview

Deteriorating environmental conditions in the places of operation of dump trucks make it necessary to look for an alternative to traditional thermal engines. Widespread use of hybrid electric propulsion systems with the use of electric energy storage devices allows to partially solve environmental problems without loss of autonomy of vehicles.

Algorithm and information processing hardware of the DC drive laboratory bench

Article preview

Virtual instruments are widely used in almost all fields of human activity. The main advantages of such systems are flexibility and versatility. At present such devices are used in the laboratory of the Department of Electrical Engineering and Electromechanics of SPGGI(TU) as a part of the SMVS-1 laboratory bench. Transients in thyristor drive are displayed on PC screen. A multifunctional device NVL 33 is the device which is designed for operation as a part of IBM PC. NVL 33 device performs the following functions: analog-to-digital conversion; digital-to-analog conversion; digital input-output; counting the number of external pulses; formation of time intervals. ADC programming includes the following operations: input switch control; gain control; ADC startup; waiting for readiness after ADC conversion cycle; ADC code readout. To observe the signal in real time, high computing power of a computer is required. Digital signal processors (DSPs) are used to solve this problem. Despite certain limitations, they are still one of the most promising means of signal processing.
