INTEGRATED SOLUTION OF THE SYSTEM OF RELAY PROTECTION AND AUTOMATIC EQUIPMENT OF
6–110 kV SUBSTATIONS ON THE BASIS OF SERIES MP DEVICES
The line of microprocessor protection devices and automatic equipment (МР3хх, МР5хх, МР600, МР7хх, МР8хх, МР90х), manufactured
by Belelektromontazhnaladka Open Joint Stock Company, completely supplies the need of 6–110 kV distribution substations. The МР
devices combine the functions of protection, automatic equipment, signalling, control, local and remote control. All МР devices have
an open line control discipline МР-СЕТЬ (Modbus analogue) and may be integrated with computer-aided control systems. On request
IEC 870-5-103 protocol may be installed (IEC 61850 — for МР76х, МР8хх, МР90х).
МР series devices have been successfully operated on the facilities of electric power systems of the Republic of Belarus and the Russian
