NTC-07.25 “Basic electric drive and converting equipment with MPCS”

Br0.00

The educational laboratory stand is designed for studying automated electric drives, power conversion techniques, drive control systems, and automatic control systems. Laboratory work enables researchers to investigate and experimentally determine the characteristics of various electric motors (including direct current and asynchronous motors), as well as control systems and converters, such as pulse-width modulation schemes, rectifiers, inverters, and broad-bandwidth pulse converters based on IGBT transistors. The exercises cover methods for identifying dynamic and static machine parameters, startup, braking, speed and current regulation processes, and automatic and positional control systems utilizing various controllers and sensors. Special emphasis is placed on experimental testing of system characteristics under different operating modes, along with analyzing how control signals and system parameters influence overall behavior.

Category: Electric drive and converting technology

Structurally, the training system consists of two parts:

case with installed part of electric equipment, electric circuit boards, countertop of integrated desktop;
machine equipment.

Laboratory experiment may be conducted in manual mode and in the mode of the dialogue with PC.

The laboratory stand is supplied with:

a set of teaching materials and technical documentation intended for the teaching staff;
software which gives opportunity to:
- repeat basic theoretical principles studied in lab;
- check students’ knowledge before conducting laboratory experiments (theoretical questions, correct circuit assembly, knowledge of hardware, step by step control of understanding the selection of the experiment circuit and measuring instruments for the implementation of specific learning objectives);
- carry out laboratory work with displaying the measured values on a computer monitor;
- implement real-time mathematical calculations of measured electrical quantities and their graphic display;
- save the data obtained and work with them when the bench is off;
- export the data obtained (graphs, oscillograms, estimates) to Office programs in order to provide convenience of subsequent reporting.
