EKRA opened the first digital electric motor drive training laboratory in Volga Region at the I. N. Ulianov Chuvash State University.
The laboratory is designed to study operation modes and control algorithms for electric motors used both in electric transport and elevators, as well as in industrial equipment: large mainline pumps that provide continuous water supply to cities or transport oil, or are even used to cool nuclear reactors.
Employees of the Medium-Voltage Converter Technology Department of EKRA have developed and assembled a unique “Integrated bench to study soft start and regulation modes of electric motors using the converter technology.” It consists of cabinets with various control principles, so that students can not only control electric motors during their studies, but also get inside knowledge of different devices and their implementation. There are several ways to monitor and control the cabinets: by various control panels built into the cabinets, by switches and lights on the outside panel, and by personal computers in the classroom.
The equipment performs the continuous intelligent protection function: electrical – from current overloads, supply voltage deviation, and technological – temperature, vibration, etc.
The control cabinet, control and switching cabinet, digital exciter for synchronous motors, frequency converter, and soft starter presented in the laboratory were fully tested and designed for operating voltage of industrial facilities.
“The laboratory equipment is designed to control electric motors, which are widely used in oil and gas, processing, chemical, mining, nuclear power, housing and utilities industries, etc. The integrated bench installed in the laboratory allows to study features, operation principle, and adjustment of modern soft start and frequency control systems. This is an example of modern digital converter technology designed to control electric machines,” Vladimir Vishnevsky, Director of the Medium-Voltage Converter Technology Department, summarized.
The new training laboratory is named after the honored inventor of the Chuvash ASSR, Nikolay Malyuk, who from 1983 to 2001 taught at the Department of Automatic Control Systems of Electric Drives of the Chuvash State University and trained many talented engineers.
