ABB improves grid reliability in Algeria

ABB Automation Technologies : 26 June, 2006  (Company News)
An ABB Network Manager solution will improve grid reliability in one of Algeria's three power distribution networks by pinpointing and isolating network faults, work that is currently done by service teams traveling in difficult mountainous terrain.
An ABB Network Manager solution will improve grid reliability in one of Algeria's three power distribution networks by pinpointing and isolating network faults, work that is currently done by service teams traveling in difficult mountainous terrain.

The solution is being installed on behalf of Sonelgaz, the Algerian state utility, and will significantly improve reliability and quality in one of Sonelgaz's three power distribution networks, the area in and around Constantine, the country's third largest city.

A significant part of the network covers towns and villages in the Atlas mountains, many of which are 1,000 meters or more above sea level, difficult to access and with limited telecommunications infrastructure. If a fault occurs, a service team has to search for its location in the field, a time-consuming process that can lead to lengthy power outages.

Real-time monitoring and network control
When the new ABB Network Manager system goes online in Spring 2007, it will resolve these challenges and give Sonelgaz real-time monitoring and control of the entire network. Operators will be able to pinpoint faults immediately, make the best use of network capacity and loading, and better manage service crews and work scheduling.

The system will be run by one primary and three secondary control centers, each equipped with ABB's Network Manager SCADA/Distribution Management System.

As part of the solution, ABB is upgrading 31 key substations with UniGear medium-voltage switchgear panels, REF542plus protection and switchbay control units, and substation automation systems based on MicroSCADA and RTU560 remote terminal units. A further 533 substations and 355 overhead isolators will be equipped with REC523 control, protection and monitoring units.
