MPEI at International Electric Engineering Expo “Electro-2021”
From 7 until 10 June, 2021, MPEI took part in the 29th
International Exposition "Electro-2021" dedicated to electric equipment, light
engineering and automation of constructions and buildings. The Exposition Has
been carried out annually by the Expo-center under the aegis of the Russian
Chamber of Commerce and Industry since 1972 and has been the largest exposition
project in Russia and CIS States of the Electric Engineering industry.
In the framework of the Exposition, the departments
and scientific centers of MPEI presented their innovations in devices and
solutions in Electric Engineering, Electronics and Automation.
The Department of High Voltage Engineering and
Electrophysics demonstrated a conductor with solid screened insulation of a
generator voltage of 10 kV with a compensated external electromagnetic field
for a rated current of up to 6000 A, which can be used for electrical
connections at power plants, in three-phase alternating current circuits with a
frequency of 50 and 60 Hz of turbine generators with a capacity of up to 1500
MW with power step-up transformers, auxiliary transformers, converter
transformers and thyristor excitation transformers of generators. The generator
voltage conductor can also be used for other energy facilities, industry,
transport, and agriculture.
The Department of Industrial Electronics presented a
semiconductor device for regulating the voltage of a transformer under load.
The device is designed to regulate the output voltage of dry power transformers
with off-circuit tap-changers at transformer substations of 6-10 / 0.4 kV class
with a rated power of up to 1 MVA in manual or automatic mode and is a modern
analogue of mechanical devices that provide voltage regulation on the Low
Voltage side. The use of semiconductor valves provides the average speed of 10
ms, which is a significant advantage. Also, the device does not require disconnecting
the transformer from the mains and the load during operation, as in traditional
regulation using off-circuit tap-changers.
The Department of Power Supply of Industrial
Enterprises demonstrated a HSAT terminal working sample. The microprocessor
terminal for high-speed automatic transfer switch of the BE1002.032 series is a
multi-element emergency control device for operation in the guaranteed power
supply systems of the first and second categories of consumers.
The Department of Electrotechnical Complexes of
Autonomous Objects presented a breakthrough technology for autonomous heat and
electricity supply based on innovative steam turbine generators, and
demonstrated high-speed turbine generators for autonomous power plants of low
power and units with variable speed for the intelligent power system of Russia.
MPEI Center for Training and Retraining and Scientific
and Educational Center "Ecology of Energy" offered visitors
information about educational centers for training and retraining of our
university in the fields concerned by the "ELECTRO" exhibition.
The MPEI exposition captivated the attention of the
visitors as usual.
