Upgrading of the remote monitoring and control system of the medium voltage network in the distribution area of Elektrosrbija Kraljevo

The upgrade of the remote monitoring and control system of the medium voltage network in the distribution area of Elektrosrbija Kraljevo was carried out from January 2018 to January 2020 across the area of ED Kraljevo, Kruševac, Jagodina, Loznica, Čačak and Užice, under investor IMP Automatika. The goal of this project was to provide monitoring of the situation in the medium voltage power network of certain branches in the area of ODS Distribucija – Elektrosrbija Kraljevo by installing modern control, communication, and energy equipment.

It is ensured that the competent dispatch centers have an insight into the condition of the complete equipment in the network at all times (e.g. the condition of disconnectors, reclosers, SF6 switches, etc.).

Images of single-pole diagrams, signals and alarm status, measurements, command keys, are displayed on the monitor of the dispatcher’s workstation. It is possible for the dispatcher to be able to control the system remotely, by giving the appropriate command. Some of the functions of the system are:

• display of equipment status 24 hours a day throughout the year via SCADA system
• possibility of fast reaction by remote means
• returning the system to normal operation, i.e. turning on parts of the system that are out of operation
• time savings due to almost instantaneous reaction, without going to the facility and intervention of technical persons
• the possibility of timely interventions in case of accidents
