Power Management – Introduction (1)
What ? Why?The control of electrical switchgear and equipment
To optimise electricity generation and usage and to prevent major disturbances & plant outages (blackouts)
Where is it required ?
In the context of a green-field installation
a major extension or modification of a brown-field plant
In plants with a substantial electrical load
In plants with major electricity generation facilities
In cases where there is no or a poor grid supply or the need to limit imported power

Reduce investment costs
Maintaining a good Power Factor
The total accumulated switched-off shortcurrents by a circuitbreaker or
the number of generator starts are a trigger for maintenanceNo need for big oversizing of primary equipment
Power Control, Standby Optimization, n+1 Criteria, SCADA, etc. are performed by
the system and not by the operators
The Human Machine Interfaces for all the electrical sub-systems can be integrated in
the Energy Management SystemSerial interfaces with protection & control units avoid spaghetti wiring & cable ducts
